Maggie was a amish puppy mill rescue. She was initially indifferent to other dogs. My friends dogs would try to play with her and she acted like they were not even there...but over time, with patience, she saw other dogs play and she started to join in! And now she adores my friends dogs, and LOVES my inlaws big sheepdog! None of these other dogs are yorkies but she is not the smallest of the crew. Anyways, we are traveling right now and I was out walking her this morning around the hotel and we ran into a woman with two little yorkies! Maggies little tail was spinning around and she was so happy she was squealing like I never heard before! This is the first time she has seen other yorkies since she was in the mill. Do you think she knows they are her breed?! It was just so interesting to me! Melted my heart. She kept sniffing them and then looking up at me like, "look mommy! yorkies!". Gahhhhh I love her!
