I actually do not have my Yorkie yet...this Tuesday I am going to pick one of 4 out of a litter 1 girl and 3 boys. I never owned a small breed dog, always large mutts! But I have always loved this breed and I'm older now...in an apartment and figured this would be a good breed for me. I have 2 adult Persian cats, who are very mellow and sweet...they were actually brought up with my old dog, and got along quite well the 3 of them. We had to put the ol' guy down a few years back. So any input for my situation would be welcomed....boy versus girl Yorkie...potty training....best food...etc.
