The history of American tracking dogs goes back to the shameful days of slavery and the hunting of escaped slaves. I did not know until I read an article from 1920 written by a West Virginia judge that bloodhounds were first imported not just for their tracking skills, but also for their strength in apprehending the slaves. The first trackers were fox hounds, but these dogs were not enough of a threat. Judge McWhorter's words, in "The Bloodhound as a Witness," are worth quoting at length:
"During the slavery days of America, the slave-holders of the south conceived the idea of employing dogs in tracking slaves who attempted to escape. There were then no bloodhounds in America, and none were imported. But the common fox hound was trained to trail the slaves, and for the purpose of keeping the slaves awed and intimidated, the reports were generally circulated that these dogs were bloodhounds, with great accent on the word 'blood,' and that they were infallible, and when put on the trail of a negro would never abandon it until the fugitive was run down and torn to shreds, and that there was no escape from such ferocious dogs. This naturally appealed to the imaginative slave, and helped to give credence and circulation to these reports.
"But by and by the slaves began to learn that these hounds were harmless, and that all the reports concerning their viciousness were false, and the 'bloodhound' began to lose his terror. To offset this trouble, the common hound was then crossed with the Great Dane, or the Cuban Mastiff, both savage and vicious breeds of dogs, and a new strain produced called the 'Cuban Bloodhound,' and later and more appropriately called the “N---r Hound.” These dogs were vicious, and the former reports of the viciousness of the so-called 'bloodhounds' were renewed and fully credited, not only by the negroes but by the whites of both North and South as well. The vivid stories about these dogs in `Uncle Tom's Cabin' had their counterparts in every slave-holding section of the country. These dogs could, with ease, track barefooted negroes through the swamps and low damp grounds of the South, and it was utterly immaterial whether the dog left an older trail for a fresher trail of another negro. Just so the dog 'treed a n---r,' the moral effect was the same. The slaves were kept intimidated, and these dogs were doing their work effectively, regardless of their accuracy.
"Thus this 'common knowledge' of the work of the 'bloodhounds' grew. These reports were exaggerated, and, without scruple, falsified and the sagacity, discriminating powers and deadly precision of these dogs magnified for the very purpose of keeping the slave terrified. In this there was eminent success. The following poem expresses this 'Common Knowledge:'
"'O’er all, the bloodhound boasts superior skill,
To scent, to view, to turn and boldly kill—
His fellows’ vain alarms rejects with scorn,
True to the master’s voices and learned horn;—
His nostrils oft, if ancient fame sings true,
Traced the sly felon thro’ the tainted dew;
Once snuff’d, he follows with unaltered aim,
Nor odours lure him from the chosen game;
Deep-mouthed, he thunders and inflamed he views,
Springs on relentless, and to death pursues.'
"But who would have dreamed at that time that these false and highly colored reports would become the basis for the promulgation of a doctrine by the courts of America that would put in deadly peril the lives and sacred liberties of American citizens? It will be observed that these dogs, from whose work this 'Common Knowledge' largely arose, or at least took its coloring, were not bloodhounds at all. They were, at best, only quarter bloods; and all these reports of the vicious character and deadly precision of the so-called 'bloodhounds' had their foundation in fact only to the extent that the blood of the Cuban Mastiff or the Great Dane had been infused into the strain. Such reports were not true of the English Bloodhound, and never were. If these facts had been thoroughly understood, I do not believe this insidiously dangerous 'bloodhound doctrine' would ever have been adopted by any of the American courts, and that when once fully understood, it will either be repudiated in toto, or so emasculated by precautionary restrictions as to render it harmless."
McWhorter's entire article is available online through GoogleBooks.

Throwing Whiskey from the Negro Coach: Racism in a 1926 Tracking Case?
Perhaps half of police dog cases in the last twenty years involve canine sniffs, often of vehicles pulled over for traffic violations. The officer becomes suspicious and calls in a canine unit to see if the dog will alert to drugs (occasionally explosives). Before World War II, however, police dog cases most often involved tracking. Some cases are worth reading for the pictures of America that they give. Consider the following description of a crime from a 1926 case in Mississippi.
"Two police officers, Parnell and Danner, and several constables had repaired to a point about two miles southwardly from the city of Meridian, where they had information that whisky had been thrown from a train before, and would be on that night thrown from train No. 2, going northwardly, toward Meridian. So arranging themselves in two groups, the two police officers, Parnell and Danner, being together, they stationed themselves on the right of way 40 or 50 feet from the railroad track, to await the coming of the train about 11 o'clock on the night of the 20th of June, 1924; that when the train passed, they saw a negro named Hezekiah Clay throw three kegs of whisky off of the front vestibule of the negro coach, and immediately after the train had passed, which was running about 20 or 25 miles an hour, the defendant appeared upon the scene, passing on to where one keg of whisky was, which was farther away from them; that the defendant took up the keg of whisky and carried it away on his shoulder, and was gone seven or eight minutes; that the two officers then moved down in close proximity to the second keg, and when the defendant came back he came toward where the second keg had landed, and stopped. The officers, thinking he had discovered them, arose, flashed their flashlights upon him, and ordered him to throw up his hands and consider himself under arrest. To this order of the officers the negro responded by firing several shots at the officers. Officer Danner claimed that he was shooting at him (Danner). The officers responded to the negro's shots with a volley, each of them discharging his gun. No one was wounded. The negro ran off toward the mountains."
Bloodhounds were placed on the trail.
"The bloodhounds trailed toward the mountains in the direction which the officers said their assailant had gone, and finally, at 4 o'clock in the morning, they trailed to the home of defendant's mother, about a block and a half from Thelma Walker's house, where the defendant says he was living with Thelma Walker in concubinage."
The defendant, Boatwright, provided witnesses that gave him an alibi, and sought a continuance to produce more, which was not granted. The kegs of whisky were introduced in evidence, but do not seem to have connected the defendant with the crime, though viewing them may have incensed the jury. The only evidence connecting Boatwright to the crime appears to have been that the dogs tracked to a house where he was living. Was there racism here? Probably. It was well settled by this time in cases that considered tracking evidence that bloodhound testimony alone was not sufficient to convict. It could only be corroborative. It may be that the appellate opinion failed to review some uncontested evidence, but anything particularly probative would likely have been mentioned since it would have provided additional support for the decision to affirm. Boatwright v. State, 143 Miss. 676, 109 So. 710 (Sup. Ct. 1926).

Scott and Fuller's 1965 Treatise Still a Gold Mine
In reading modern authors on dog evolution and behavior, such as Coppinger and Miklosi, one finds many references to a book published long before modern genome technologies, Genetics and the Social Behavior of the Dog, by John Paul Scott and John L. Fuller (U. Chicago Press, frequently reprinted). I had avoided reading the book because I feared that its relative antiquity would mean that I would constantly be reminded how far science has come in understanding the genetics of dogs. To the contrary, once I picked the book up, I found it hard to put down. The authors may not have had all the modern tools of molecular biology, but their discoveries are phenomenal and every page is full of valuable observations, some of which have never been stated better. It’s such a brilliant work that I have no doubt I will be reading it again soon. Just two passages will be quoted here. The first concerns the evolution of dogs:
Then there’s the following on the overbreeding of champions, an issue I’ve discussed here before:
Adaptive radiation on a smaller scale [i.e., smaller than what happened with mammals once reptiles (dinosaurs) had been eliminated as major rivals] seems to have taken place soon after the dog became domesticated. Within the various human societies, dogs found a whole new habitat. The dog, as one of the first domestic animals, was a remarkable social invention, both for protection and as an aid to hunting, and every tribe must have wanted to get hold of one. In this way dogs spread rapidly over the world, differentiating as they moved, and so produced the southern short-haired varieties like the dingo and, at the opposite extreme of their range, the northern Eskimo dogs which are almost like wolves. A further multiplication of habitats was provided when the herd animals were domesticated. Now dogs were needed to protect those herds against their own close relatives, the wolves, which found the domestic beasts easy prey.
Then there’s the following on the overbreeding of champions, an issue I’ve discussed here before:
The desirability of multiple standards makes the practice of breeding a champion to a large number of females within a breed a questionable one. Almost every animal carries some sort of injurious recessive genes, and this practice insures that they will be spread throughout the whole breed, with resulting disappointment as the descendants of these champions are eventually bred together and the recessive traits begin to show up in large numbers. The breed objectives should not be the development of a single, fixed type—something which is only possible by strict inbreeding—but rather for the development of a population varying within desirable limits and within which new and more valuable combinations of genes will always be possible.

Court Would Not Pick Up Bill of Drug Dog Expert for Defendant
When charged with a narcotics offense, the chain of evidence often includes an alert of a drug dog. A significant proportion of traffic stops that balloon into drug busts involve a canine sniff of the vehicle. The sniff justifies a further search, uncovering drugs, paraphernalia, and/or large amounts of cash. The defendant may attack the alert of the drug dog, though this will seldom work unless there has been a very long delay before the dog was produced, or perhaps if the only thing uncovered in the subsequent search is a large amount of cash. In moving to suppress the drug dog evidence or the fruits of that evidence, the accused may request funds from the court to retain his own expert when he cannot afford one. Such a request was made by Willard Wayne Howard in a case arising in Tennessee.
The facts of U.S. v. Howard are as follows. On December 12, 2005, officers of the Bradley County, Tennessee, Sheriff’s Department pulled over Antonio Benitez, who was driving a Volkswagen Passat. Five kilograms of cocaine were discovered in a secret compartment in the car, but this search was not at issue in the case. Benitez was taken to the sheriff’s office where one of the cell phones that had been found in the car rang and was answered by a deputy. The deputy told the caller that he worked for a towing company and that the Passat had been wrecked. He gave the caller the cell phone number of another deputy, but said that the number was that of the towing company. Amy Cornwell, Benitez’s girlfriend, called that number and said that she and her stepfather would drive to Tennessee to pick up the Passat. Two days later she arrived with Willard Howard in a Chevrolet Suburban. She went to the wrecking company where a deputy named Renner was impersonating an employee. Renner said that he had found a secret compartment in the Passat but that he would not tell the police if she gave him $500. She said she did not know what he was talking about. Renner arrested her anyway, Other officers arrested Howard and led a drug detection dog named Titan around the Suburban. Titan alerted at the rear door of the car. A search revealed nearly $100,000 in cash.
A magistrate determined that the arrest of defendant was illegal, and denied Howard’s motion for an appointment of an expert. The federal district court for the Eastern District of Tennessee held that the evidence from the search of the Suburban could still be admissible if Titan’s alert was an independent source for the search of the vehicle, i.e., was not dependent on the illegal arrest. Based on this conclusion, Howard moved for reconsideration of the denial of the motion for appointment of an expert. The expert Howard wanted was Robert Gonzalez, who had for five years been the Branch Manager of the 37th Security Forces on Lackland Air Force Base in Texas. In this capacity, Gonzalez managed all military working dogs on the base. He was also selected by the Air Force Headquarters Security Police to be the Team Leader, trainer, and coordinator of the U.S. Customs Canine Drug Interdiction Force for Puerto Rico. Gonzalez was clearly qualified, but the issue was whether the court should pay for him since Howard apparently could not. (It is not explained whose cash the $100,000 was or why Howard was in need of funds.)
Howard argued that an expert was needed to determine if the National Narcotic Detector Dog Association (NNDDA) had an acceptable certification process, to determine the dog’s performance and training records, and to determine if Titan had reliable alerts. Titan was certified by the NNDDA. The court then considered what use Gonzalez could be to Howard in this regard and said that there was no evidence that Gonzalez had experience with this particular organization, though he had considerable experience with detection dogs. Implicitly the district court signaled that it saw no point in a dispute between a large national organization and an expert with a different background. Nor could Gonzalez describe the alerts of Titan, a dog with which he had never worked.
The magistrate subsequently determined that the independent source doctrine applied to admit the search of the Suburban. U.S. v. Howard, 448 F.Supp. 889 (ED TN 2006); magistrate’s report and recommendation (2007). The NNDDA website provides certification standards for police dogs, narcotics detection dogs, explosive detection dogs, and cadaver dogs. As of 2006, the NNDDA had between 2,500 and 3,000 handler members.

Cadaver Dogs Help Solve Cold Case
Michelle Dorr was six years old on May 31, 1986 when she disappeared from her father’s house in Silver Spring, Maryland. Carl Dorr, Michelle’s father, reported her missing at 4 o’clock that afternoon. He told the police that he was not exactly sure when he had last seen his daughter, but thought it was shortly after lunch, about 1 o’clock. He seems to have left her unsupervised in the backyard for several hours before noticing that she was no longer there. Carl Dorr was immediately the prime suspect. The police interviewed him aggressively, which did not allay their suspicions. They kept him under surveillance, tapped his phone, reviewed bank and video rental records, questioned his employers, co-workers, friends, neighbors, and family. Dorr had a series of nervous breakdowns. He announced that he was Jesus Christ and said he could bring Michelle back to life. He was hospitalized, but suffered another breakdown on release. He made incriminating statements, saying once that he had suffocated Michelle and put her body in a sewer. He also said he had buried her near his father’s grave. Michelle’s mother appeared on America’s Most Wanted and said her ex-husband had killed their daughter. Carl saw the television program and went to his ex-wife’s house. He demanded to be let in and said he knew where Michelle was and that the truth would burn a hole in his wife’s soul.
Lost in the police files accumulated after Michelle’s disappearance were some other pieces of evidence that did not point to Carl Dorr. Neighbors of Carl Dorr named the Binders had seem something that did not seem so significant at the time. Their neighbor on the other side, Geoffrey Clark, had been allowing a ne’er do well brother named Hadden to stay with him. Hadden was moving out of his brother’s house the day of Michelle’s disappearance, and the Binders, when asked if they had seen anything unusual, said they had seen Hadden loading a duffle bag and a trunk into his white pickup. But this was no later than 12:20, a time fixed by the Binders, because they had left then or before to attend a baptism. Loading a duffle bag was not, however, very suspicious. First, Hadden was moving. Second, this had occurred at least forty minutes before Carl Dorr said he had last seen his daughter.
Hadden was intereviewed twice by the police. The first time was nine days from Michelle’s disappearance and was not informative. The second was three days later. In the second interview, Hadden asked to be excused and went into a bathroom where he cried and vomited. When he returned an officer asked him what he had done to Michelle. “I don’t know,” he replied. “I may have blacked out. I may have done something.” Hadden asked to speak to his psychiatrist. He was permitted to leave the police station. Carl Dorr remained the prime suspect.
In October 1992, over six years later, a 23-year-old woman named Laura Houghteling disappeared. Hadden had worked as a handyman at her family’s residence and Hadden became a suspect in this crime, which revived the memory that he had been interviewed in Michelle Dorr’s disappearance. On October 31, 1992, Hadden arrived at his sister’s home in Rhode Island, where he complained to her that the police were trying to pin a crime on him because he was homeless. That night he went to his family’s plot and camped there for the night. When he returned to Maryland, Hadden Clark was interviewed concerning the disappearance of both Laura and Michelle. Officers went to the cemetery where Hadden had spent the night and found the soil near the family plot had been disturbed. Similar soil was found in Hadden’s truck.
A cadaver dog named Dan came with his handler, Massachusetts State Trooper Kathleen Barrett, to the cemetery. Dan alerted to an area near the headstone. A second cadaver dog named Panzer also alerted to the same spot. Hadden Clark pled guilty to second degree murder in Laura’s death and was sentenced to thirty years in prison. While in prison, Hadden gave two cellmates a description of how he had killed Michelle six years before Laura. He said he had found her playing in his niece’s room (the niece and her parents were not home at the time) and cut her up with a butcher knife. He told his cellmates that he had put her in a trash bag and then in a duffle bag which he had loaded in the back of his truck. This was the event noticed by neighbors, but initially ignored because it was inconsistent with the time frame of Michelle’s disappearance as given by her father.
Because of the description of Michelle’s death that Hadden gave to his cellmates, the room where he had described killing her was sprayed with luminol, which causes blood to become luminescent. There was a lot of blood, consistent with Hadden’s story. Curiously, DNA testing eliminated Michelle as the source of the blood.
The police theorized that Hadden had removed the body of Michelle the night he spent at the cemetery after he became a suspect in Laura’s death. Although this was not established on the record, Hadden was finally convicted of second degree murder in Michelle’s death. Michelle’s body was later found, alerted to by Panzer. Clark v. State, 140 Md.App. 540, 781 A.2d 913 (Md.Ct.Spec.App. 2001). See Alec Wilkinson, “A Hole in the Ground,” The New Yorker, p. 64 (September 4, 2000).

Are Breeding Programs Reducing Genetic Variability?
There are various conflicts in the dog world. Choke vs. no-choke in dog training. Treats vs. other rewards. One that I’ve encountered more in the last few years are disputes between those who want to keep breeds pure vs. those who believe in crossing in other breeds. Some remarks near the end of Adam Miklosi’s wonderful book, Dog Behavior, Evolution, and Cognition (Oxford University Press 2007) are worth considering:
"Today dogs are subject to a dangerous ‘game’ which involves irresponsible playing with one tiny aspect of their phenotype: the form. This leads to two important problems. Breeders are encouraged to inbreed in order to fulfil the requirements which lead to genetically homozygous populations, and the absence of selection for behaviour leads to the disappearance of breed-specific traits. Thus this trend brings nothing good for dogs in terms of their evolution because genotypes are being lost and genetic variability is decreasing."
Miklosi then cites P.D. McGreevy and F.W. Nicholas, whose article, “Some Practical Solutions to Welfare Problems in Dog Breeding,” 8 Animal Welfare 329-341 (1999), argued that breeds should not be considered closed populations, and dogs from other breeds should be crossed in. This would not change the appearance of the breeds, as breeding programs can create virtual breeds, as was done with the Pharaoh Hound (described by Miklosi, in another section of his book, as “probably a fake ‘look-alike’ recently created from different types of dogs”).
My father, M.E. Ensminger, would have agreed with the notion of breeding in animals from other breeds. In his treatises on Animal Science, Beef Cattle Science, and other books, he placed a high value on “hybrid vigor,” recommending that breeding programs regularly cross in other breeds to improve production. He had the advantage of working with the livestock production field where appearance is important, but other qualities, such as the amount of muscle that becomes hamburger, were even more important. Consequently, I'm not aware that he encountered much resistance to his arguments. (His books are still in print, being revised under a trust arrangement by staff at Iowa State University.)
Those concerned with dogs losing behavioral characteristics as a result of crossing in other breeds should consider the research of Kenth Svartberg, a Swedish scientist, who studied breed differences using tests of over 13,000 dogs in 31 breeds. Svartberg concluded that selection was often being dominated by show dog breeders, and that their programs were producing good show dogs, but that the behaviors correlated with the breed origins, often inconsistent with what is required for a show dog, were disappearing. Kenth Svartberg, “Breed-Typical Behaviour in Dogs—Historical Remnants of Recent Constructs?” 96 Applied Animal Behaviour Science 293-313 (2006).
My aunt, Lee Watts, was a well-known poodle breeder in Canada. She used to say that if you didn't get a purebred dog, "you don't know what you're getting." I still hear it when I go to obedience classes. What she didn't know, and what Svartberg's research indicates, that you may be getting the right form, but as time goes on you're not getting the same complex of behaviors. Domestication does not stay still for other factors, even if the form stays still.
"Today dogs are subject to a dangerous ‘game’ which involves irresponsible playing with one tiny aspect of their phenotype: the form. This leads to two important problems. Breeders are encouraged to inbreed in order to fulfil the requirements which lead to genetically homozygous populations, and the absence of selection for behaviour leads to the disappearance of breed-specific traits. Thus this trend brings nothing good for dogs in terms of their evolution because genotypes are being lost and genetic variability is decreasing."
Miklosi then cites P.D. McGreevy and F.W. Nicholas, whose article, “Some Practical Solutions to Welfare Problems in Dog Breeding,” 8 Animal Welfare 329-341 (1999), argued that breeds should not be considered closed populations, and dogs from other breeds should be crossed in. This would not change the appearance of the breeds, as breeding programs can create virtual breeds, as was done with the Pharaoh Hound (described by Miklosi, in another section of his book, as “probably a fake ‘look-alike’ recently created from different types of dogs”).
My father, M.E. Ensminger, would have agreed with the notion of breeding in animals from other breeds. In his treatises on Animal Science, Beef Cattle Science, and other books, he placed a high value on “hybrid vigor,” recommending that breeding programs regularly cross in other breeds to improve production. He had the advantage of working with the livestock production field where appearance is important, but other qualities, such as the amount of muscle that becomes hamburger, were even more important. Consequently, I'm not aware that he encountered much resistance to his arguments. (His books are still in print, being revised under a trust arrangement by staff at Iowa State University.)
Those concerned with dogs losing behavioral characteristics as a result of crossing in other breeds should consider the research of Kenth Svartberg, a Swedish scientist, who studied breed differences using tests of over 13,000 dogs in 31 breeds. Svartberg concluded that selection was often being dominated by show dog breeders, and that their programs were producing good show dogs, but that the behaviors correlated with the breed origins, often inconsistent with what is required for a show dog, were disappearing. Kenth Svartberg, “Breed-Typical Behaviour in Dogs—Historical Remnants of Recent Constructs?” 96 Applied Animal Behaviour Science 293-313 (2006).
My aunt, Lee Watts, was a well-known poodle breeder in Canada. She used to say that if you didn't get a purebred dog, "you don't know what you're getting." I still hear it when I go to obedience classes. What she didn't know, and what Svartberg's research indicates, that you may be getting the right form, but as time goes on you're not getting the same complex of behaviors. Domestication does not stay still for other factors, even if the form stays still.
Additional Note. The effect of letting show appearance
dominate the breeding programs of a particular dog was decried long ago.
Captian von Stephanitz, discussing the Scotch shepherd dog or collie in The German Shepherd Dog in Word and Picture
(1923), noted that it is divided into "two varieties, a short smooth haired, and
a long smooth haired kind, from which originated the long haired dogs so prized
by the fancy breeders…. In the Shetland Islands, where the dwarf horse is bred,
there is a dwarf variety of this collie.”
He then says a picture of a long haired dog that was “a prize winner of
some reputation, shows how far one-sided and exaggerated breeding may go till
it becomes unnatural and a caricature.
The collie of the fancy dog breeder is now only bred for beauty and is
kept for luxury and show; with his slender small head and overbred face drawn
out into an overlong nose—(this part from the tip of the nose to the division
in the forehead is much longer than the cranium, while the proportion should be
the reverse). Then there is the carriage of the ears, where only the upper
third of them should tip over; but must only droop over that much, otherwise it
is considered a great fault—(to the fancy breeder the erect eared Scotch dogs
such as are also seen today are villainous rogues, worthy of death), and in
conclusion the hair is everything…. The daily ‘toilet’—here the word must be
understood in the English sense—of a collie beauty takes hours to perform; especially
before an Exhibition.”
After discussing the show preparations that he finds
offensive, Stephanitz then delves into the uselessness of the dog for real
work:
“He lives more on the good reputation built up by the yeoman
services of his ancestors, which he no longer knows how to perform. That is the
meaning of the vacuous appearance of the shallow, unintelligent, ant-eater-like
too elongated head…. The present day fancy Scotch dog with his slender needle
like sharp teeth can tear very savagely and make serious wounds, but these
qualities do not fit him for service with flocks and hers; and further, he
lacks the strength necessary to stop and turn a stubborn sheep.”

Psychiatric Service Dog Society Gets Transportation Department to Rethink Air Carrier Access Rules
The Department of Transportation has taken the somewhat unusual step of publicizing some criticisms that have been raised concerning its 2008 revision of the air carrier access rules (73 Fed. Reg. 27614, May 13, 2008). The criticisms come from the Psychiatric Service Dog Society (PSDS), which criticized 14 CFR 382.117(e), which reads as follows:
(e) If a passenger seeks to travel with an animal that is used as an emotional support or psychiatric service animal, you are not required to accept the animal for transportation in the cabin unless the passenger provides you current documentation (i.e., no older than one year from the date of the passenger’s scheduled initial flight) on the letterhead of a licensed mental health professional (e.g., psychiatrist, psychologist, licensed clinical social worker) stating the following:
(1) The passenger has a mental or emotional disability recognized in the Diagnostic and Statistical Manual of Mental Disorders—Fourth Edition (DSM IV);
(2) The passenger needs the emotional support or psychiatric service animal as an accommodation for air travel and/or for activity at the passenger’s destination;
(3) The individual providing the assessment is a licensed mental health professional, and the passenger is under his or her professional care; and
(4) The date and type of the mental health professional’s license and the state or other jurisdiction in which it was issued.
The Department of Transportation notes that PSDS criticizes that failure of the regulations to distinguish psychiatric service dogs from emotional support animals. This is a valid objection in my opinion, but in the interest of full disclosure it is appropriate that I acknowledge that I have co-authored with Dr. Joan Esnayra, founder of PSDS, a letter to Treasury and the IRS regarding the deductibility of service dog expenses (published in Tax Notes, August 24, 2009; contact me at jensminger@msn.com for a copy). PSDS argues that by classifying PSAs with ESAs, DOT is effectively distinguishing PSAs from other service animals and imposing additional requirements on handlers of PSAs that it does not impose on handlers of service animals for the physically disabled. PSDS notes that this will encourage users of PSAs to claim physical disabilities in order to avoid the additional requirements of the regulations.
Many people with mental health-related disabilities use general practitioners and do not receive treatment from licensed mental health professionals on a regular basis. The rule lists only psychiatrists, psychologists, and licensed clinical social workers as examples of licensed mental health professionals. Obtaining a letter from a mental health professional would be particularly burdensome for individuals who do not have medical insurance or access to affordable medical care. Providing an airline 48 hours advance notice (14 CFR 382.27(c)(8)) of a passenger’s intention to fly with a PSA is also difficult or impossible in certain short-term situations such as family or medical emergencies, and would exacerbate the mental health professional documentation issue. .
DOT paraphrases one PSDS position as follows:
The rule violates the medical privacy of PSA users by requiring confidential medical information to be provided to airline personnel. Moreover, the rule makes no provision for the confidential treatment of this information once it gets into the airline’s hands, and fails to answer questions concerning the security, storage, or use of the information. PSDS expresses the concern that the Transportation Security Administration could gain access to the information and require additional security measures (e.g., secondary screening) for persons identified as having mental health-related disabilities.
DOT responds that it does “recommend that the carrier take steps to safeguard this information, such as maintaining it in a separate confidential file for the same time it retains the passenger’s reservation record for the flights involved.” DOT specifically asks for comments about this issue, and seems amenable to a more restrictive policy. This should not be a difficult modification, since DOT could require airlines to provide such safeguards as would assure that records are not available for other purposes than to verify a passenger’s status, and not available to staff beyond those needing to access such information.
The release indicates that DOT “has not decided whether to grant the petition by initiating rulemaking action or deny the petition and retain the provisions without change.” Nevertheless, the release concludes with a number of options that the agency might consider, including targeted modification of certain provisions. The issues raised by PSDS are significant. It is to be hoped that DOT will consider some modifications to the final rules. Comments may be submitted online, by mail, fax, or courier. Instructions are contained in the Federal Register, 74 Fed. Reg. 47903, left column. Online is easiest: just go to http://www.regulations.gov and follow instructions using DOT Docket ID # OST-2009-0093. Comments must be received by December 17, 2009.
