Hi Michelle and welcome to YT. I think alot of it has to do with socializing your yorkie pup to little kids in the beginning. Pasquale met my nephew the first day i got him. They are best buddies. In fact, Pasquale can tell the difference between an adults voice and a childs voice...and gets super excited when he see's a child. He absolutely loveeeeeeeeeeeeeeeeeeeeeeeeeeeeeeess kids! Remember, lots of training and socializing!!
