thanks for the confirmation (not that it matters by this point)! when i took him to the dog park last weekend, 2 women approached me and insisted that he's a silky. they both own silkies. so that got me thinking...that's all. i guess i truly cannot tell them apart at all. at first (when he was younger), he looked all yorkie to me and now i keep on thinking that i have a silky. so when people ask me what kind of dog he is, i'm totally confused as to what to tell them. they think i'm crazy for being so inconsistent in my answers. =)
he has been neutered. i have tried to socialize him, but i also baby him greatly. so maybe that's why he's so mean towards everyone else (including my boyfriend sometimes)?
either way, i am looking into a behaviorist this weekend. thanks again for all of your help! it is much appreciated.
