BeaCon Voluntary Open Health Registry
Year 7 General Report
March, 2008
Welcome to BeaCons Open Health Registry Report for year 7. It is amazing how many years have
passed since the concept of an open registry was mulled over by the BCCA health committee in fall 1998.
After BeaCon incorporated in April 1999, the open health registry was initiated and this is our seventh
year of recording wellness and potentially genetic
health conditions for the breed.
Resistance to entering dogs persists due to fears that a breeder and his/her kennel will be maligned. That
is a very real fear and it demonstrates how far the Beardie community has yet to travel before the breeds
health becomes the highest priority for everyone.
This dilemma needs to be addressed because breed numbers have declined in recent years (at least in the
USA; see a later section for the figures). Consider the factors listed below and you should grasp the
concern:
Lack of widespread participation in the open registry by breeders and the related restriction of
openly available information,
A 5.4 point higher average coefficient of inbreeding (10 generations) of USA registry dogs
compared with original USA foundation stock
The phenomenon of the popular sire use which lowers genetic diversity over generations
(
http://www.beaconforhealth.org/Popular_Sire.html
Particularly new breeders face limited amounts of information when trying to make the most informed
decisions that should include known health concerns.
Thus, the directors of BeaCon want to thank each and every Beardie owner and breeder who has made
their information publicly available through this open health registry. You are a treasure for current and
future breeders as you create an important legacy. For those who only put in their healthy dogs and dont
report those with health problems, please reconsider for the sake of future generations.
Who May Participate?
ALL BEARDED COLLIES of known parentage
Deceased or living
Healthy or with a health problem
From any country
The primary owner, a co-owner, or a breeder (as of spring 07) may submit information, but written consent
is always required from all the owners.
Why Are Healthy as Well as Those with Health Problems Important?
The largest number possible is needed to give a complete picture of the extent of wellness or health
problems.
To allow calculation of disease incidence. There need to be enough dogs to calculate disease frequencies
that are applicable to the general population of Beardies, not just those in the open registry.
o
For example, if there are 57 dogs with Addisons in 916 dogs, the frequency of Addisons is 5.9%.
If the total number of dogs is 1800 dogs, the frequency is significantly lower, 3.1%.
To provide whole family information which breeders can use for relative-risk pedigree analysis in diseases
that are autosomal recessive.
To provide data for researchers.
To allow prospective puppy buyers data on health of Bearded Collies which may enable them to make
more informed choices, or at least know what questions to ask breeders.
Who May Submit Information
Owners with whom the dog lives.
Year 7 Report for BeaCon Open Health Registry, March 2008. Page - 2
-
A co-owner. The primary owner (defined as the person with whom the dog lives) must send in a signed
consent.
A breeder. Starting in the spring of 07, a breeder may also submit information. The primary owner must
send in a signed consent. In the case of a breeder entering pups in a litter prior to sale, if their contract
notes the pup is in BeaCons open registry that suffices as consent.
Breeders who enter a sire or dam into the registry can indicate if the dog has produced a disease in
offspring. This policy was started in year 3 because breeders are not always able to convince their puppy
buyers to participate in the open registry. It is vital to know about certain health conditions in offspring.
Specific diseases of interest are Addisons, symmetrical lupoid onychodystrophy, systemic lupus
erythematosus, and hypothyroidism. Any disease can be noted in the other category; e.g., autoimmune
hemolytic anemia or immune-mediated thrombocytopenia, or polyarthritis, or a heart condition. Dams
producing a disease can have the number of cases and the litter (s) indicated. Sires producing a disease
may have the number of cases indicated. The name of a dog with the specific disease produced cannot be
listed.
A dogs information is not publicly available if entered by a co-owner or a breeder until the primary
owners consent is received.
How To Submit Information.
This may be done either by hard copy form or on-line at
www.beaconforhealth.org/sqlweb.
Documentation.
No changes have been made from previous years. Copies of health screening test results are
requested. This is especially important for dogs from countries other than the USA. We attempt to validate the
information for USA dogs through the on-line registry databases (OFA or CERF). When that is not possible, it is so
noted in the dogs report.
Health screening tests that have not been submitted to another registry can be included in the registry. Preferably, a
copy of the documentation form is sent to BeaCon; e.g., a copy of the CERF ophthalmologists exam for an eye
exam.
Updating.
Reminders are sent late each calendar year to owners of all living dogs in the registry as of the most
recent data entry. Updating should be done yearly, even if the dog has had no changes. You can also update
whenever there has been a change in your dogs health or new health screens done at any time.
If you have entered a diagnosis which is later changed, contact
beaconbb@bellsouth.net
with the new information,
or log in to your account and make the change yourself.
Pedigrees and Coefficient of Inbreeding (COI).
Every effort is made to be accurate in the pedigrees. As
new dogs are entered into the database, a five generation pedigree is generated offline and posted. Owners are
notified and asked to confirm accuracy of the pedigree. Data for pedigrees come from many sources including
pedigrees submitted by owners, the Kennel Club Breed System Bearded Collie database updates, and online
databases. With the advent of the on-line registry system, fewer hard copy pedigrees were submitted; thus the
dependence on other sources. Pedigrees are generated with Breeders Assistant, starting in January 2006. If an error
is found in a pedigree, please notify E. Sell (
beaconbb@bellsouth.net
) with the correct information.
A COI is the mathematical definition that elucidates closeness of relationship in a pedigree. It is usually expressed
as a percentage and it was developed by Sewall Wright (Coefficients of inbreeding and relationship. Am Nat.
56:330-8, 1922). Basic principles are that inbreeding only exists if the ancestor appears on both sires and dams
side of the pedigree.
COIs can be calculated, but it is complex, and various online sources describe how to do this. It isnt complex if
one uses a pedigree software program with the built in calculation. The Breeders Assistant software was used to
calculate 10 generation COIs as reported further on.

Use of Data and Caveats.
Viewers of the open health registry data are responsible for interpretation and use of
the information. The purpose of this registry is to give objective data on disease and wellness, not to draw
conclusions about any particular line, sire, or dam.
We caution the reader that a sire or dam cannot be assumed to be a carrier of an undesirable genetic trait simply
because that health problem is reported in a single progeny. Furthermore, some genetic diseases may be influenced
by environmental factors, not yet defined.
Geneticists believe the following circumstances are indicative of heritability:
Relatively frequent occurrence of the disease
When mating a sire and dam several times results in the same health problem in more than one litter.
When a dog or bitch mated with different mates results in the same health problem in several litters.
If several dogs from the same kennel are reported with the same problem, you cannot assume that the problem
occurs with high frequency. You have to know the status of the other dogs from that kennel before making any
assessment regarding prevalence. This means that full participation by a breeder is important, rather than selectively
entering just healthy dogs in the registry.
Many hereditary problems, other than those transmitted by an autosomal dominant mode of inheritance, involve
healthy parents, one or both of whom are carriers of the genes responsible.
Information that a particular dog or bitch has produced a problem is vital to any breeder. This is especially critical
for novice breeders just establishing their programs because they are least likely to have a good network for finding
and verifying such information.
BeaCon encourages breeders to enroll pups in BeaCons Open Health Registry before they go to their new
homes. Having a large number of healthy young dogs to follow over the long term is an optimal resource to
determining frequency of diseases in any breed.
The inclusion of dogs in this registry is by the free choice of the owner/co-owner. Absence of dogs from this registry
is also by the free choice of the owner/co-owner. Notice of the registrys availability is made through resources
available to BeaCon: BeaCons newsletter (Lighting the Way) and web site (
www.beaconforhealth.org
), and
Beardie internet lists.

How Many Beardie Collies are Born in the USA?
This year for the first time we include a table showing several sets of figures about the numbers of Beardies in the
USA. The data start with 1977 when the breed was recognized by the AKC. All data come from AKC reports;
some are standard reports and some are special reports. The decline in number of litters and number of pups in
registered litters from 2002-2006 was statistically significant, as reported in Lighting The Way.
Since the number of dogs registered with AKC in a given year may include imported dogs, as well as USA dogs
born late in the prior year, we also have the number of foreign born, AKC registered dogs. The registration system
in the USA leaves it up to a puppy buyer to register their dog. Unless AKC adopts a procedure similar to the UK
(where breeders register individual pups that is not left to the puppy buyer), the AKC dog registration figures
wont be an indicator of the number of dogs born here.
In 2007 the number of USA born and registered Beardies (405) was very near that in 1977 (397) 30 years
previous. There is some relief to be found in this seemingly distressing decline from two sources:
(1)
AKC dog registrations for a number of breeds have been declining in recent years
(2)
The number of USA born pups increased in 2007, compared with 2006.

This Year A Quick Look.
The Netherlands has participants for the first time (27 owners and 74 dogs), due to efforts of several people. Also
Hungary and Slovakia are represented for the first time.
There are 491 participating owners, an increase of 81 from the previous year, and 1203 Beardies, an increase of 242.
There is little change in the frequency of the most common health problems; fear issues and autoimmune problems
continue to lead the list. The frequency of health screens is little changed.
Puppy mortality is about 5% stillborn and an additional 7-8% dying by 6 weeks of age.
Participation.

Owners from one new country participated this year, the Netherlands; they provide 74 new dogs to the registry.
This happened because of enthusiasm for the registry and engagement of owners by several leaders.
Health Problems.
A higher percent of dogs were healthy this year, 55.8% vs. 47.7%. This reflects entry of
younger dogs, and some of these were put into the registry as young pups before going to their new owners.
Frequency of specific health problems is reported if there are more than 20 cases. Some owners entered health
problems only into update notes; all effort has been made to also create a health problem record from the update
notes for a more accurate accounting.
A caveat of both the healthy dog and disease frequencies is that they apply to this specific population of Bearded
Collies. It wont be possible to speculate if the findings are applicable to the broad population of Beardies until
several thousand more dogs are in the registry.

diseases.
Autoimmune Problems
(# diseases = 167; # dogs having diseases = 135, or 11.2% of all dogs). Although the
frequencies appear to be unduly high in this population of Bearded Collies (i.e., in the open health registry), it is not
known if the figures are applicable to the general population of Bearded Collies world wide. That will remain
unknown until a much larger number of dogs are in the open registry.

MDR-1 5
The frequency of individual health screening tests and the various combinations were minimally changed from the
previous year. MDR-1 stands for multiple drug resistant disease gene; that gene is mutated in some dogs of some
breeds who have inability to readily clear certain drugs across the blood brain barrier. The result can be
neurological effects, such as seizures in certain Collies after taking excessive doses of ivermectin. All five Beardies
reported in the registry had a normal MDR-1 test.
Of interest, there are several working Beardies in the registry. One breeder has had eye exams done on breeding
stock of working origin and for several generations. This has been done because of concern that breeding standard
registry Beardies to a working Beardie would introduce eye problems in the progeny. To date, all eye exams have
been normal. For a current litter of third generation working Beardies, the great great granddam (KC registered)
was normal 9 years of age. The granddam (first generation working dog) has had four normal exams, the most
recent at 6 years 4 months (a sister not being bred was normal at a younger age). The dam (second generation
working dog) and four littermate sisters are normal at 4 years 1 month. Six 2 month old puppies (3 bitches and 3
dogs) are normal; they are the third generation working dog breeding.
Reproductive Outcome

** Among the problems were 5 puppies with heart problems (3 PDA; 1 persistent right aortic arch); 1 each
produced hyperthyroid, discoid lupus, autoimmune hemolytic anemia, pyelonephritis (early death at 3 wks), kidney
failure (several died as young dogs), exocrine pancreatic insufficiency.
Mortality
. There are 271 (22.7%) deceased dogs. There may be others also deceased but their owners have not
responded to update requests. Autopsies were conducted on 20 (7.4%) deceased dogs. Owners should remember
that autopsies will sometimes be helpful in establishing the cause of death. If more autopsies were done in those
where death is not due to very old age and related maladies, there would certainly be more identifiable causes of
death.
Mode of death was natural in 35, euthanasia in 207, accidental in 10, and not documented in 19.
Causes of death in different age groups are given below.
The leading causes of death before 9 years of age were autoimmune (n=14, 26.9%) and accidental (n=10, 19%) for a
cumulative total of 45.9%. The final report of the BCCA 96-98 health survey found 30% of deaths before age 9
were due to autoimmune causes. This is of concern and focus should be on supporting research to identify cause(s)
of the problems, and hopefully elimination of these problems where feasible.
Cancer was the leading cause of death for 9-14 year olds and old age takes over thereafter.
