The four dogs we had heart examined yesterday and all were heart murmur free (which you can read about on the blog Heart results: Toby gets his over 5 years old clear heart certificate) will be traveling to Bristol the beginning of August to be MRI scanned at The Downs Veterinary Practice on the BVA - CM / SM scheme.
Today I learnt something about the BVA - Eye scheme. I always thought it was just for purebreeds (I think it may of in the past), but read on their website today, "The BVA/KC/ISDS Eye scheme is based on eye examination and is a means of identifying inherited and non-inherited ocular conditions in dogs. The majority of dogs presented for examination under the Eye Scheme are pedigree dogs with known inherited diseases of the eye, but all dogs, including cross breeds, can be examined. This approach reassures breeders that the dogs they are to use for breeding have healthy eyes and the inclusive approach means that new and emerging problems are more likely to be recognised."
So Bumble, Toby, Ernest and Blottie will be traveling to Tavistock at the end of the first week in August to the Westmoor Veterinary Hospital to have their eyes examined by Chris Warren. I've also ordered two DNA sampling kits to see if either or both Bumble and Blottie have inherited the one copy of the mutation for Episodic Falling their Mum Smudge carries.
When we DNA tested all our Cavaliers in 2012 for Episodic Falling and Dry Eye Curly Coat Syndrome. We found no dogs with or carrying Dry Eye Curly Coat Syndrome, but found one of our bitches Smudge to be a carrier of Episodic Falling. A carrier is a dog that has one copy of the mutation and one copy of normal DNA. These dogs will not develop the condition themselves but they will pass the mutation on to around 50% of their offspring. These dogs do not need to be excluded from a breeding program, but will need to be bred to Cavaliers that are not carriers and are either DNA tested CLEAR and have two normal copies of DNA or have had both of their parents if Cavalier DNA tested CLEAR.
If Bumble and Blottie are carriers it is not a real problem, as Toby has been DNA tested CLEAR for this condition and his son Ernest who we hope to use, his mother Treacle a first cross Cavapoo her Cavalier mother Dolly is also DNA tested Clear for this condition and her father Reggie a Miniature Poodle Episodic Falling has never been reported in this breed and seems very breed specific to Cavaliers at this time.
DNA testing Blottie and Bumble to see whether they have inherited this one copy of the mutation from their mum Smudge is firstly so that if either or both carry it I can inform anyone having a puppy from them that if they ever decide to breed from that puppy (Yep, I don't mind people breeding from dogs they get from me. When I sell a dog, I don't think I own it's breeding rights. If healthy and good tempered. Why would I not want that dog to be bred from?) that they should get the puppy either DNA checked for this or if using a Cavalier or part bred Cavalier to breed with that the Cavalier or part bred Cavalier has been tested CLEAR for Episodic Falling. Secondly, it is also for my on going records and I hope that neither have the one copy of the mutation, but realistically it is more likely at least one of them carry it and they possibly could both carry it. As I said before though, "it is not a real problem" but one that I should be keeping an eye on.
