Bearded Collie Club Summary of the Kershaw,E., Wilkins, A. and McBride E.Anne
(2015) Report of the UK Bearded Collie Breed Liaison Committee Health Survey 20072012 by Elizabeth Ayrton
Introduction
The Bearded Collie was a working breed used for droving and herding which originated in Scotland.
By the beginning of the twentieth century breed numbers were very low and it was in the 1940s that
Mrs G.O.Willison founded the Bothkennar Kennels to which most Kennel Club registered Beardies
can trace their ancestry. The breed is now kept predominantly as a pet.

This therefore means that the original gene pool of the present day dogs was small. This has
implications for breed health as inbreeding was inevitable in the early days due to the small
population size.
In 2006 the Companion Animal Welfare Council reported on welfare problems in pedigree animals.
This report was the subject of the 2008 BBC documentary (Pedigree Dogs Exposed) which
highlighted health problems in many pedigree dog breeds. Following on from this the Bateson inquiry
in 2010 looked at this issue in depth and made recommendations regarding inbreeding, inherited
disease, selection for extreme morphologies, welfare and buying and selling of dogs. One aspect that
became increasingly apparent over this time was the lack of data in individual breeds. The Kennel
club did carry out a survey in 2004 which provided some data and they have repeated this at the end
on 2014. The Bearded Collie Breed Liaison Committee therefore decided to run a survey in 2012, in
collaboration with the University of Southampton to collect data in order to build up a picture of
health in the present day UK Bearded Collie.

This survey was an ambitious project with data collected in 2012 on UK owned dogs in the period of
Jan 2007 to Jan 2012. Data was obtained and analysed on 700 dogs, 511 alive, 188 dead and one
respondent did not say whether her dog was alive or dead. I will briefly summarise and comment on
the main aspects but refer interested readers to the whole survey which contains more in depth
information and statistical analysis. ( see reference at the end of this report to access the survey.)
These 700 dogs can be broken down into 319 males (211 entire and 108 neutered) and 379 females
(192 entire and 186 neutered.)
Dead dogs
Age of death varied from 1 year 5 months to 19 years 11 months with the average being 13 years 2
months. It is encouraging to see that many of these dogs lived into their teens.
Living dogs
These varied in age from 2 months to 17 years 2 months. Data was collected looking at neutering,
breeding, colour, management, exercise, mental activities and vaccination.
Disease
75.29% of the sample reported at least one illness (not including parasites). Dogs could be recorded
as
having
more
than
one
illness.

Sensory Issues
Sight
The biggest issue reported here was old age cataracts. This may or may not be correct. A normal
aging process in the canine eye involves a loss of elasticity of the lens called nuclear sclerosis this
appears as a bluish cast to the eye which to the untutored eye looks like a cataract.
Hearing
40 dogs were reported as deaf and 93 had temporary ear infections. The auditory nerve does
deteriorate with age so some of this deafness could be related to older dogs and also how deafness
was confirmed, hard of hearing is not the same as deaf. There was mention of deafness in relation to
white and merle coats but neither of these colours is recognised in the UK breed standard. Temporary
ear infections are of concern as are more chronic ear infections as they can be painful and debilitating.
Management has a part to play here as Beardies are prone to hair growth in the ears which can
predispose to ear infections unless kept under control.
Dental
A range of problems were reported but all at low levels.
Musculoskeletal problems
A range of problems were reported the largest of which was osteoarthritis, this is not totally surprising
in a breed which lives to an old age. The age of onset of osteoarthritis is a factor that is useful to
monitor as osteoarthritis in young dogs would be an area that would certainly be worthy of further
investigation.
Cancers and Tumours
The incidence of individual cancers and tumours were too low to perform any analysis. 11 dogs were
reported with liver cancer and 13 bitches with mammary tumours.

Conclusions
This was a very ambitious survey which provided some good data to try and look at health in the UK
Bearded Collie population. Hip scoring is currently the one health test required for the Bearded Collie,
however 20 dogs bred from that were not hip scored which is disconcerting. All animals intended for
breeding should be hip scored before mating. There were 2 incidents of elbow dysplasia and this
needs to be monitored as there is a scoring system for elbows available. There are a huge number of
DNA tests also becoming available for various diseases so we need constant information to be able to
choose the most appropriate tests to ensure breed health.
Eye testing of all breeding stock would monitor for inherited eye problems and could be combined
with litter screening for CEA (Collie eye anomaly) where the CEA status of parents is not known.
Levels of autoimmune disease are worrying and at present there is still much research in this area that
needs carrying out. It would have to be strongly recommended, however, that any mating that
produces puppies with AI should not be repeated. In addition any dogs suffering from AI should not
be bred from. Breeders should also avoid close inbreeding and overuse of popular sires to avoid
inheritance of homozygous genes that could contribute to AI problems and also to slow down the loss
of genetic diversity within the breed.
There is a need for continual health surveillance within the breed and therefore it has to be a strong
recommendation that Bearded Collie Clubs promote and work with the Vetcompass project which
collects data continually from participating vet practices. This could be combined with our own
surveys and Kennel Club Surveys to try and monitor breed health on a continual basis and advise on
any appropriate action to take
