Yep, the dog I know that has and she is a Yorkie. That article was just something I found. ( must be common in Weatons). I don't know for sure if it's what your dog has but it sounded like the same thing. Mabey copy the articles on the two issues and see what the vet says. I think the Yorkie owners vet knew right away after 1-2 tests. Her food is now ZD (hills). Hope you find out whats up and your baby is feeling better soon. It's so expensive test after test and still no answers.
