I have a 17 week old Yorkie and his feet are really, really webbed. (and big) I just noticed this. He is also quite large at 4 months he is already 10lbs. I have AKC papers for him and have been told it is possible for them to get this large. What's up with the webbies though? Can he swim? I can find little info online about this for Yorkies. Any help would be appreciated
