I think this is normal behavior. Yorkies love to have playmates to socialize with especially if it is another yorkie. Teeka is 6 months and loves to play with her yorkie cousins! They will rough house for hours or until they tire. Then she seeks me out for cuddle time. I love that she is so sociable and happy to play with others. My first yorkie did not socialize with other dogs or people and she did not like any one but me to pick her up of hold her. She would growl at other dogs, too. So with Teeka, I have made every possible time to get her to socialize with other pups, people and even a bunny, who loves to play! They learn so much from playing with other pups! Give them time to bond with each other and they will always come a running when they want some snuggle time with their mom!
