| Breeders, Owners, and Liver Shunt In some recent research I was doing I came across the results to date of the studies on Liver Shunt done at the University of Tennessee, and have discovered that breeders who happen to come up with Liver Shunt in their lines may not be at fault, at all. This is some of what I read: 1. Bred normal Yorkie to normal Yorkie got LS puppies. 2. Bred normal Yorkie (m,f) to LS Yorkie (m,f) got normal pups. 3. Bred LS Yorkie to LS Yorkie got Normal pups. 4. Bred normal Yorkies past 5 generations and still got LS pups. 5. Some Yorkies do not develop LS until they are older, after they have been BAT tested negative and been bred, so pups sold prior to discovery carry the gene. 6. Recommendation stands to neuter and spay any parents and/or litters that ever test positive for LS until future discovery allows for a more suitable protocol in controlling this inheritable defect. I just wanted to throw this out for all to ponder, and to warn folks not to let your guard down, if your pup is LS negative, still be aware of the symptoms just in case. Maybe something like a stem cell vaccine could be developed to replace the missing step in a LS pup's developement that causes the shunt not to close at birth that could be given to the mom's sometime before delivery. Or given to a dog that develops LS later in life. As it seems LS can rear it's ugly head anywhere, anytime, no matter how conscientious a breeder may be, maybe we can all work together at reporting cases better with a no-fault policy to get to the bottom of this dreaded disease. Just a thought.

| This is certainly true. My baby had a liver shunt, and it was repaired a U. of Tenn. I think it would be a good idea to have your yorkies b a t's checked at least every 2 years. Just to be safe. I have heard of yorkies that 7 years old having liver shunts. But be aware that any dog can have a liver shunt, so it is a good idea for everyone to know the signs of a liver shunt..

| Copied & pasted from U of T Website: INHERITABILITY OF PSS/MVD PER DR. TOBIAS (2/2/04) We feel very confident that it is genetic, but we don't know how it's passed. We know that it can skip generations. Here is the info I've gotten from the literature and our research: In Yorkies we see it when certain lines are bred together. We have breeders that have avoided breeding their lines to another specific line for 4-6 generations, because they got a shunt the first time they bred the two lines together. When they breed the 5-7 generation dogs back to that line, they get a shunt.
