The AKC, like the United States, is a governing
body that sets basic policies and “laws.” Parent breed clubs, like
states, pass policies “ laws” valid within their own boundaries or jurisdictions.
Club policies must be consistent with AKC policies.
Traditionally the main functions of the breed
clubs have been to oversee the breed standard of perfection, organize national
and regional specialty shows or competitions, and perhaps offer annual
challenge trophies. Beyond these minimal duties, the quality and
services of parent clubs vary widely among breeds. Many also offer
judging seminars, breed information pamphlets and rescue contacts.
Many if not most breed clubs maintain Internet web pages. Many breed
clubs have a standing health and ethics committees, but again, the quality,
scope and authority of such committees varies.
Parent breed clubs develop breed standards and
maintain stud books and petition AKC for recognition of the breed and the
breed club. Even after agreeing upon a standard, the parent club
may consider amendments to it, and if deemed appropriate, change the standard.
In developing a standard, a parent club exerts tremendous power over the
genetic future of a breed. In some cases, standards require physical
characteristics that are inconsistent with hardiness. For example,
brachycephalic features predispose a dog to breathing difficulties, diamond
shaped eyes to entropion and/or ectropion, excessive wrinkling to moist
dermatitis, and excessive size coupled with deep chests to gastric torsion
(bloat). In most of these cases, the breed standards were drawn up
long before the association of these traits with physical difficulties
was known.
Such traits have become so ingrained as basic
to breed type that breeders and parent clubs choose to retain them despite
their associated problems. Since the parent club has sole discretion
over the breed standard, only the breed club can effect a change in the
standard to change the essence of type and reward healthier, but less traditionally
typey, specimens. In almost every case in which type has been at
odds with health, parent clubs have chosen to give type precedence.
The results are obvious!
Breed standard disqualifying faults also affect the genetic health of a breed. The AKC has several disqualifying faults applicable to all breeds; perhaps the best known of them is unilateral or bilateral cryptorchidism (the failure of one or both of the testicles to descend normally into the scrotum). Since this fault is less detrimental to health than a plethora of other far more serious faults with far greater heritability, the universal disqualification of such dogs is of questionable value to any breed. Several parent clubs impose further disqualifications, usually for traits considered extremely untypical for the breed. Common disqualifying faults are for dogs over or under a certain weight or height, for different eye color, or coat colors or types. Dogs with disqualifying traits cannot be judged at a conformation show, but may compete in other venues. By banning these dogs from conformation competition, parent clubs hope to discourage breeding from them and perpetuating the offensive trait Removal of dogs from the breeding population based upon arbitrary aesthetics can do more harm than help, especially in cases where the breed has a limited gene pool and the banned trait has no strong hereditary component.
Lack of appreciation of genetic aspects of a trait
can result in illogical and detrimental disqualifications. One example
is the “Boston” Great Dane. These dogs are black with typical “Irish
marked” coat pattern, that is, white feet, tail tip, muzzle, and collar,
just like the typical pattern of the Boston Terrier. This color pattern
has been listed as a disqualifying fault since the AKC approved the standard
in 19**. Yet serious breeders of harlequin patterned Great Danes
continued to use Bostons in their breeding programs. Breeding a harlequin
to another harlequin results in, on average, 25% harlequins, 25% merle
(disqualified), 25% white (disqualified) and 25% Boston (disqualified).
In addition, of the harlequins produced, only about half
have show quality markings. Breeding a
harlequin to a Boston, however, results on average in 25% harlequin, 25%.
Thus, a majority of dogs produced from perfectly acceptable colored parents
will be disqualified from breed competition by virtue of the combination
of acceptable genes that together produce an unacceptable color pattern
for this breed. These dogs may be of such high quality otherwise
that they are sought after for breeding back to harlequins, especially
because their use as a breeding partner to a harlequin actually results
in a greater percentage of acceptably colored offspring than would a harlequin
to harlequin
breeding. Unfortunately, because these
Bostons are disqualified form competition, their quality has never been
able to be objectively judged by way of conformation awards or titles.
It was obvious to many that the standard with these disqualifications was
senseless. Finally, in 1996, in recognition of the importance of
the dogs to the breeding of harlequins, the Great Dane Club of America
voted to change the breed standard to accept the Boston colored (now renamed
“Mantle”) Great Dane as an acceptable color.
Changing the standard is one of the largest responsibilities
that a parent club traditionally can take, and to do so in recognition
of genetic mechanisms is a progressive step for a parent club. Unfortunately,
not all clubs have shown such an ability to accept genetics over tradition.
In other breeds, disqualifications have been implemented in recognition
of health problems related to certain traits. In 1979, a “white”
Doberman Pinscher named Sheba was AKC registered. She was undeniably
eye-catching, with a light cream coat, translucent blue eyes, and pink
nose and eye rims. Her offspring were crossed to each and produced
more such dogs. These striking animals
aroused much interest, but were apparently tyrosinase positive albinos.
Not only were these dogs considered untypical for the breed, but because
albinism can be associated with health problems, especially those from
ultra violet exposure, the Doberman Pinscher Club of America acted to not
only disqualify these dogs, but worked with the AKC to develop a scheme
whereby dogs possibly carrying the gene for albinism could be identified
by their registration numbers. Such dogs are identified with a “Z”
as part of the litter or individual registration.
Besides overseeing the breed standard, most parent clubs hold national or regional specialty shows for their breed. Most clubs furnish lavish trophies to the winners so that many participants can barely haul their loot back home with them. Winning these events carries such prestige that the trophies are simply icing on the cake. The Saluki Club of America has for years instead opted to award modest momentos of wins at its specialty shows, with trophy donations instead going toward the “Humane Purse.” This money is donated in the Best of Breed winner’s name to a humane or research organization to further the welfare of dogs.
EDUCATION
Specialty shows can be more than a showcase of
dogs. At no other time can so many earnest breeders and owners be
found congregated in one place. Though informal social events are
an integral part of such gatherings, some clubs do little more than schedule
dinners, awards banquets, and parties. While some parent clubs are
taking the opportunity to present educational events to the fancy, most
events are more likely to center around judging issues than health issues,
and are usually restricted to a relatively short seminar that may conflict
with other concurrently scheduled events. These seminars are extremely
important functions, but could be supplemented by additional “poster” sessions
much like those seen at scientific meetings. In these a question or problem
is posed and explained by way of a simple poster presentation, so that
interested persons can study those topics that interest them at their own
pace. Many such posters covering a wide range of topics could be
presented during a day long session, with the poster presenters (the experts
on that subject) available to explain the posters during certain time periods.
At the same time health screenings could be performed
for various genetic problems, including cardiac and ophthalmological screenings,
and DNA samples could be collected. Time must be set aside for these
functions; unfortunately, given the choice of a party or education, too
many exhibitors rend to choose the party.
In recent years, most parent clubs have formed
breed health committees, the success of which depends upon many factors.
Larger clubs have a larger membership from which
to draw educated and dedicated committee members. Some clubs still
operate under closed memberships, however, in which prospective members
must be sponsored by existing members and voted upon by the full membership.
Such clubs too often resemble sororities and their membership reflects
“who likes whom” rather than who can help the breed. Because intellectual
abilities and interests do not always reflect popularity, many qualified
people are discouraged from even applying to such clubs. Unfortunately,
interest in club politics does not appeal to everyone,
and sometimes those in control of the club are
those with greater interest in being a leader than in actual knowledge
of the breed. Political issues are rampant within any breed, and
control of the parent club is control of the breed standard---and ultimately
the future of the breed. Thus, in breed clubs with small membership, because
of either small breed numbers or exclusionary practices, the chance of
forming a strong health committee is considerably lower than in those clubs
with a large membership. There is a concept, somewhat “tongue-in-cheek”
but containing a grain of truth, that some dog club members are
socially inadequate and that by purchasing club
membership (dues) they can have a social experience they would otherwise
not have. Over time, such persons tend to gravitate to club office
progressing through the less desirable offices to their final rewards.
Much as in the “Peter Principle[i],” club officers tend to be incompetent.
The first step a breed health committee faces
is identification of health problems. This step is not as simple
as it may seem.
Breeders may have a “feeling” about what may
be a problem based upon personal experience and anecdotal reports.
The problem then becomes one of determining whether these problems are
breed specific or common to all breeds. For example, if a breeder
knows of ten dogs over the past three years that suddenly fell over dead
at a young age, this might raise some suspicion that the breed had a problem.
But perhaps this is no more than would be seen in any breed of dog. The
problem is that 95% of that breeder’s contacts also have the same breed
of dog; it would be very unlikely that the breeder would ever hear about
the same circumstance in another breed simply because of lack of communication.
Thus, a major problem in breed
specific health surveys is one of bias.
While it is unrealistic to expect parent clubs
to have the expertise conduct statistically sound and unbiased health surveys,
they are being forced to shoulder this responsibility. Some have
done a better job of tackling it than others. The greatest barrier
to parent club health surveys is lack of trust on the part of breeders,
since those collecting the information are often that breeder’s competitors.
Though hiding health information may seem petty and dishonest, recall that
many breeders have a lifetime of hard work, study, money, and emotion invested
in their line of dogs. They fear that if they are the only ones to
come forward with
information, they may be the only ones branded
as having unhealthy dogs, effectively terminating the line to which they
have devoted their lives. In popular breeds much of the information
thus comes from individual pet owners In some other breeds efforts
are undertaken to ensure anonymity. For example, the Salukis In Good
Health Committee developed a process in which identifying information and
medical information pertaining to a dog are sent in separate sealed envelopes,
coded by a “middle-man”, and sent on to separate data entry people so that
no person ever sees the medical and identifying information together.
Only in the final step are the two sets of information associated within
a third database that encrypts the information
so that actual identification of animals is still
inaccessible to committee members. It is this information that is
ultimately used for performing analyses.
Code of Ethics
Most parent breed clubs maintain a standing
ethics committee to develop, maintain and enforce some form of code of
ethics.
Such codes are known by various names such as
Guidelines for Responsible Ownership[ii], Guidelines for Breeders[iii],
Guidelines for Ethical Conduct[iv], Ethical Guidelines[v], Mandatory Practices[vi],
Principles of Integrity[vii], Statement of Conduct[viii], Canon of Ethics[ix],
Breeders
Code[x] and Code of Recommended Practices[xi]. There are several
more variations upon this theme, but in general, the parent club codes
of ethics make vague and not very binding statements about genetic health,
ranging from no mention at all, to actually listing the diseases of interest
and the screening required.
Parent clubs have a serious internal political
problem when establishing a standing ethics committee, with the result
that some clubs have yet to progress this far. Other clubs have official
committees, but they are kept out of sight and out of mind. In some
clubs, because of the personalities and beliefs of some of the more successful
members, have severely controlled or thwarted the actions of such committees.
When one of the more successful breeders with more champions bred and shown
refuses to screen for hip dysplasia, the club is often powerless to enforce
screening requirements. In such cases, genetic screening becomes
“recommended,” “encouraged” or “should be considered.”
There are several breed clubs that do in fact list the screening that should be done and say that such screening is mandatory under the code of ethics. A number of codes of ethics mention the Orthopedic Foundation for Animals, but no other registry such as the Canine Eye Registration Foundation. This is a step in the right direction, but we find virtually no evidence that anything has been done to discipline or terminate membership of any successful breeder who fails to follow the club’s screening regimen.
In fairness to breed clubs, it is difficult in a litigious society to attempt to force any sort of genetic testing without that attempt resulting in internal lawsuits. If changing a breed standard to add a comma to correct punctuation is difficult, think of how difficult it might be to establish a genetics committee to interface with an ethics committee and develop a genetic screening regimen appropriate to the breed. Imagine the legal tests when a successful (usually wealthy) breeder is censored by some means for not conducting such screening.
The answer lies in educating the club membership.
Advertisements of top dogs need to include the genetic screening supporting
them. Articles need to be frequently published in the club and breed
magazines/newsletters questioning the folly of purchasing a dog from anyone
that did not have an effective genetic screening regimen. In our
democracy, the free market exerts the force for change that is otherwise
prevented by the costs of litigation. The puppy buying public is
slowly becoming aware of the problems of genetically inferior dogs.
States are rushing to enact puppy lemon laws. AKC is becoming known
as the registry of sick dogs. Any breed club’s attempt to rise above
the mire will serve to differentiate that breed from the “You don’t want
one of those, they have a lot of health problems.” Individual breeders
can enhance the desirability of their puppies by documenting generations
of genetically healthy get.
Money
The development of genetic tests is an expensive
and time consuming process. Often the same disease in two distinct breeds
is the result of a different mutation in the genome. This requires a separate
test for each breed. With the advent of the AKC Canine Health Foundation,
individual clubs are able to raise money for genetic research and have
that money matched by grants from the foundation. Other benefits of using
the AKCCHF are: their ability to screen and evaluate research proposals,
locate qualified research facilities, supervise and assess on-going research
projects, and prevent the duplication of management and
administrative functions, thus saving time and
money.
DNA Sampling
Even more important then money is the raw
material needed to conduct the research and this is where the individual
breeders and breed clubs can make a most necessary and invaluable contribution.
Without blood or bucal swab DNA samples, accompanied by accurate and appropriate
pedigrees, genetic research cannot continue to advance. See Fig.1 for examples
of pedigrees needed and some sampling strategies for isolating disease
genes and determining their mode of inheritance. With this information,
tests can be developed so that breeders will have the tools to make informed
and responsible breeding decisions, and rectify some of the extensive
health problems our dogs suffer.
The authors strongly suggest that breed clubs look at the heritable diseases associated with their breeds, and establish a well-defined screening protocol mandatory for all dogs owned or bred by members of the club. The AKC Canine Health Foundation is there to help you. Furthermore, we suggest that the code of ethics include a statement to the effect: “Members, when advertising any dog, bitch or puppy, in any venue, will include in that advertisement the genetic screening conducted on that animal and its parents.” Such mandates are within the prerogative of breed clubs, and only they have the power to correct the current appalling situation of poor genetic health. It is time to stop bashing the AKC—“we are them and they are us.” The responsibility for requiring genetic screening rests squarely with the parent clubs. The gauntlet is down! Is there a parent club willing and capable of picking it up?
Following are representative extracts from a sample of various breed clubs codes of ethics:
Akita—“I will keep well informed in the
field of genetics and work to eliminate hereditary defects from the breed….I
will participate in a program of hip x-raying and eye examinations by qualified
veterinarians to eliminate hip dysplasia and congenital eye problems. When
an Akita has hereditary faults of such nature as to make his or her use
for breeding detrimental to the furtherance of the breed, that dog shall
be neutered/spayed.”
Basenji—“Ethical breeders should discuss openly
and honestly the genetic and physical problems that have occurred in their
lines. This should include the potential of these problems to be
passed on, especially in cases where testing can indicate only that a dog
is currently free of a problem, but cannot determine that the problem or
the ability to pass it on will not be inherited.
Stud dogs or brood bitches who produce offspring
of consistently poor quality or with genetic problems known to be
inherited in the breed are therefore of no value as breeding stock and
should not be used again.”
Basset Hounds—“Breedings will be directed toward producing Basset Hounds of exceptional quality in breed temperament, Basset Hound type and ability to hunt game. Only healthy and mature dogs and bitches free of congenital defects and of characteristic breed type, sound structure and temperament shall be bred.”
Borzoi—“No animal selected for breeding should
have any serious hereditary defects as determined visually and by veterinary
examination.”
Chesapeake Bay Retriever—“Be aware of genetic defects which can be harmful to the breed. When breeding, endeavor to select animals that will reduce the incidence of genetic problems while enhancing the positive attributes and abilities of the breed. Be open with all persons interested in the welfare of the Chesapeake Bay Retriever and discuss possible physical or temperament defects in your own stock.”
Dachshund—no statement concerning genetic fitness for breeding
Doberman Pinscher—“All dogs offered at stud shall not be bred prior to one (1) year of age nor after twelve (12) years of age and shall be in good health and free from communicable diseases and disqualifying genetic faults.” …Any bitch accepted for stud service must be at least 18 months of age, in good health, and free from communicable diseases and disqualifying genetic faults.”
English Cocker Spaniels—no standing ethics committee.
Statement of Conduct is silent on genetic health.
Field Spaniels—“Breed only healthy and mature
animals who are free from serious congenital and hereditary defects.”
Golden Retrievers-- “Owners of breeding animals shall provide appropriate documentation to all concerned regarding the health of dogs involved in a breeding or sale, including reports of examinations such as those applying to hips and eyes. If any such examinations have not been performed on a dog, this should be stated.”
“Animals selected for breeding should:
(i) be of temperament typical of the Golden Retriever breed; stable, friendly, trainable, and willing to work. Temperament is of utmost importance to the breed and must never be neglected;
(ii) be in good health, including freedom from communicable disease;
(iii) possess the following examination reports in order to verify status concerning possible hip dysplasia, hereditary eye or cardiovascular disease:
Hips: appropriate report from Orthopedic Foundation for Animals; PennHip; Ontario Veterinary College; BVA/KC Hip Score (Great Britain) or at least a written report from a board-certified veterinary radiologist (Diplomat of the American College of Veterinary Radiologists).
Eyes: appropriate report from a Diplomat of the American College of Veterinary Ophthalmology (ACVO), or from a BVA/KC approved ophthalmologist (Great Britain).
Hearts: appropriate report from a Diplomat of the American College of Veterinary Medicine, Cardiology Specialty.
Consideration should be given also to other disorders
that may have a genetic component, including, but not limited to epilepsy,
hypothyroidism, skin disorders (allergies), and orthopedic disorders such
as elbow dysplasia and osteochondritis.”
German Shepherd Dog—no statement of genetic health
in the Breeders’ Guide.
German Wirehaired Pointer—“Only those dogs free
of recognized genetic defects shall be used in a breeding program.”
Italian Greyhound—“If a dog or bitch has produced
any offspring with serious inherited defects detrimental to the animal's
well being, such as but not limited to blindness, luxating patellas, blood
disorders, PRA, cataracts, glaucoma, deafness, lameness or impairment of
the vital functions, and produces like results with a different mating
partner, the owner shall refrain from further use of this animal for breeding.”
Irish Setter—“Make every effort to learn about
the structure, anatomy, action, behavior and other inheritable traits
of the Irish Setter. To use this information to adhere to the breed standard
and produce sound, healthy dogs with good temperament…..To use or give
service only to registered stock that is believed to be free of serious
abnormalities which are considered inheritable….When selling an Irish Setter
known to manifest hereditary defects considered to be detrimental to the
breed, use written contracts or spay/neuter agreements to prevent the dog
from being bred.”
Miniature Pinscher—“Breed only mature animals
in good health, free from communicable diseases and major genetic faults.”
Pekinese—no mention of genetic health in Code
of Ethics
Pointer—“Only animals of quality with characteristic
type, sound structure and temperament, and free of congenital faults should
be bred.”
Pugs—no mention of genetic health in Code of Ethics.,
Rhodesian Ridgebacks—“Only dogs screened and certified
clear of hip dysplasia shall be bred. Breeders are encouraged to screen
for all appropriate hereditary disorders.”
Rottweilers—“Breed only AKC registered dogs and
bitches which have OFA certified hips (or HD-free hips as certified by
foreign counterparts of the OFA). Imported Rottweilers must have OFA hip
certification within six months after arrival in U.S.A. If semen is used
from an imported Rottweiler, the dog must be x-rayed and certified by the
OFA or foreign counterpart at no less than 24 months of age. Breed only
dogs and bitches of stable temperament with no disqualifying physical faults
according to the AKC Rottweiler Standard (i.e. entropion, ectropion, overshot,
undershot, wry mouth, two or more missing teeth, unilateral cryptorchid
or cryptorchid males, long coat, any base color other than black, absence
of all markings.) Offer at stud with a signed written
contract, only mature (two years of age or older) healthy dogs with OFA
certified normal hips, free of communicable diseases, having none of the
faults listed in Section 2 above. Refuse stud service to any bitch not
meeting the same requirements. Breed only bitches two years of age or older
with OFA certified normal hips, in good health, free of communicable diseases,
having none of the faults listed above in Section 2, to not more than one
stud dog at any one season, and not more than two out of three consecutive
seasons. Plan all litters with the goal of improving the breed.”
Saluki—“All dogs offered at stud and all bitches to be bred shall be free from communicable diseases and serious genetic defects. When evaluating breeding stock each member shall duly weigh the presence or probability of genetic disorders in the Salukis under consideration. Each member shall take every precaution, consistent with the best medical knowledge available at the time of the breeding, to avoid the perpetuation of such disorders.”
Samoyed—“Each litter is the result of conscientious planning, including consideration of the parents’ freedom from hereditary defects, type, soundness, temperament and general conformance to the official standard of the breed. The SCA member must be particularly concerned with the proper placement of puppies, both pet and show potential. The SCA member only breeds healthy, mature Samoyed adults, preferable 24 months of age, but at least 18 months of age. Prior to breeding any Samoyed, the SCA member obtains certification that its hips are normal from the Orthopedic Foundation for Animals, an equivalent foreign registry, or from a board approved radiologist and has its eyes certified free from genetically transmitted defects by a certified Veterinary Ophthalmologist. The SCA member knowingly breeds Samoyeds only to other registered Samoyeds.”
Scottish Deerhounds—“Breeders are urged to breed
only dogs and bitches that are in good health and of such maturity (yet
not past their prime) to demonstrate a degree of freedom from genetic defects
breeders are urged to test for health defects, where possible.”
Shih Tzu—“In my breeding program I will keep alert for and work to control and/or eradicate inherited problems and conditions that are particular to my breed, and breed as closely to the standard of the breed.”
Silky Terriers—“All breeding stock should be of sound temperament, free from congenital defects such as blindness, deafness and dysplasia. Dysplasia of the hips and shoulders may be ascertained by x-rays taken and read by a veterinarian who is familiar with the proper procedure and diagnosis.”
Visla—“Breed only those dogs who are free of serious hereditary defects including epilepsy, progressive retinal atrophy, von Willebrands, entropian and cranial muscular atrophy and who are over two years of age and have been x-rayed nd OFA certified as free from hip dysplasia.”
Weimeraner—“Choose only healthy parents of good
temperament and qualities in relation to the Weimaraner 's AKC-approved
official standard, and whose hips have been X-rayed and certified free
from hip dysplasia by either the Orthopedic Foundation for Animals (OFA)
or any ABVR certified veterinarian . 3.Not use dogs with hereditary defects
or disqualifying faults for breeding.”
Yorkshire Terriers—“Prior to breeding, owners
of stud dogs and bitches will adequately screen for both infectious and
hereditary diseases, using current techniques as well as those developed
in the future.”
