East Anglian Collie Association Logo Health Register for Rough Collies

The Kennel Club maintains a database of recognised health test results for all breeds, which includes clinical eye results and Hip and Elbow Assessments under the KC/BVA Scheme, in addition to DNA test results for a variety of inherited conditions.

To make Rough Collie health statistics more easily accessible to breeders, this Health Register includes KC/BVA Hip and Elbow assessments, clinical eye test results, DNA (genetic) test results for MDR1, CEA/CH, PRArcd2 (the early onset form of PRA) and DM etc. A DNA test provides a more accurate result than the subjective CEA clinical test, which often proves inaccurate.

For the register to work efficiently, test results of affected Collies should also be submitted. When searching for a stud dog, breeders should always consider a dog’s health status alongside its physical qualities. If, in the breeder’s opinion, the overall quality of a dog outweighs a particular health issue, then he/she should consider carefully the benefits
or otherwise of using that dog in his or her
breeding programme.

Key to the Health Register

It can be confusing when faced with the varying terminology used by the different laboratories so, for ease of use and consistency, we are using the Kennel Club’s terminology as follows:


KC/BVA & ECVO Eye schemes: Clinical CEA and CPRA test results
(Centralised PRA, the
form of PRA which affects British-bred Collies, and for which there is no genetic test available) are noted as either Unaffected or Affected.


DNA test results: MDR1, CEA/CH, DM and Generalised PRArcd2 (the early onset form of PRA which affects American-bred Collies) are noted as:


Clear (Normal or +/+) This dog possesses two clear (dominant) genes, one of which is passed to its offspring at conception. A dog DNA tested as ‘clear’ is free of the ‘disease’ and can only pass on a clear gene to its offspring.


Carrier (Clear carrier or +/-) This dog possesses one clear (dominant) gene and one hidden (recessive) gene. Although a carrier is ‘clear’ of the particular ‘disease’ it still ‘carries’ the hidden recessive, mutated, gene. A copy of either the clear or mutated gene is therefore randomly passed on to its offspring at conception.


Affected (-/-) This dog possesses two mutated (recessive) genes and will therefore show symptoms of the disease. The dog can therefore only pass on an affected or mutated gene to its offspring.



The COI for Rough Collies is currently 13.5% and 10.8% for Smooth Collies As more breed health information is processed by the Kennel Club, it will amend these figures annually.


Inbreeding Co-efficients (COI’s). ‘Inbreeding’ is defined as the mating of two either closely or distantly related individuals. The inbreeding coefficient of a particular dog is based on the probability that two copies of the same gene have been inherited from a common ancestor ie one shared by both parents. The lower a dog’s inbreeding coefficient, the less chance that this will happen eg. An inbreeding co-efficient of 12.5% means there is a 1 in 8 chance (ie one pup in a litter of 8) that a puppy will inherit the same version of a gene (either beneficial or deleterious) from a dog or bitch that appears in both the sire and dam’s pedigrees.

Hereditary clear.  When both sire and dam are DNA tested clear for
a specific condition, all their offspring are automatically clear and therefore classified as ‘Hereditary clears’ (occasionally you may find this referred to as ‘clear by parentage’).


Please note:  With regards to the CEA test, the KC will currently only accept DNA test results from Optigen. However, the Pastoral Breeds Health Foundation is hoping that Animal Genetics CEA test will also be acceptable to the KC in the near future - at half the price!


To encourage breeders to DNA test their stock, the EACA accepts DNA test results from any reputable laboratory, providing the web master/Health Coordinator is in receipt of a valid certificate.

N.B. The Register is open to any Rough Collie, from any country.
The dog’s country of residence is stated against its name.



If you wish to include
your collie’s details on the
register, please send the following information to
the eaca’s
health coordinator,
pat hutchinson:


registered name of dog

date of birth

Sex

Colour

Reg’d names of sire and dam

copies of all health test
certificates + a

good quality, high resolution image (preferably profile).



The  register is divided into
nine sections, and dogs
and bitches are combined
in alphabetical order
as follows:


AB - C - DH - IJ -

KL - MR - S - TV - WZ


Although the data has been carefully checked, errors
may occasionally occur so
please inform the
webmaster of any
amendments required. Don’t forget to keep your contact details up to date.


**there are currently 212

rough collies on the
health register**


Knowing the genetic health status of a given dog or bitch is hugely beneficial for breeders as it enables them to estimate the health status of their puppies as follows:


Clear to clear = 100% clears

   Clear to carrier = 50% clears & 50% carriers

Clear to affected = 100% carriers

Carrier to carrier = 25% clears,  50% carriers & 25% affected

Carrier to affected = 50%
carriers & 50% affected

Affected to affected = 100% affected                                                  affected




today’s dog breeders have a number of important aspects to consider when deciding on the suitability of two dogs being mated together. the emphasis that each breeder places on these will vary according to what they are trying to achieve:


Breed type & characteristics

Temperament

Health status

Genetic diversity
