awww don't worry about being a over-protective yorkie parent! i think most yorkie parents, esp those on YT are just a little over-protective....BUT its hrad not to be when they are so small right? just be attentive and if something seems odd, don't over-react too much and just go to the vet for a little check-up. b/c yorkies are so little things can progress quickly... but don't worry! there's tons and tons of info on YT so you're off to a good start.
welcome by the way!
yea never buying a dog from a pet store EVER AGAIN! its just a bad idea anywhere in the world i think. kikko is 6 months old now, and just finished his meds last week and so far doing well. what do you feed your coffee by the way? I know some dog food brands available in the states i can't find here. and i heard eukanuba (which kikko ate at the pet store) is really bad, so i've switched to another food already.
