[fabioadams]

I was just wondering. I don't know alot about yorkies. We adopted fabio from the pound. I had always wanted a yorkie so when I saw him I had to have him. To me he looked like a yorkie. The vet said he couldn't tell. I read books on yorkies before I got him. But still have unanswered questions. So my questions are, What is the difference between my tan colored yorkie and the dark haired yorkies? Also, how can I tell if he is full bred yorkie? What are the most common inherited sicknesses yorkies get? Besides the collapsing trachea the vet told me about. Thanks guys!
