dont worry... my bfs yorkie, Bambi was the same way when i got my baby Nala. Bambi was also 2.5yrs old when i got Nala. she used to love coming over to my house to play, but she just hated to if Nala was there. she would growl at her and try to bite her, not actually biting her... i think she was trying to show she was the boss. we used to not be able to keep them together very long bc my bf was worried bambi would bite baby nala, but i didnt put up with bambis attitude. I scolded her if she would growl or bite. so she stopped that quickly, but she was still not her same self. she kind of acted scared... i did research online and it showed they learn more that they are friends if u take them on lots of walks together. then they learn they are in the same "pack". u let them explore and have fun together, then they will begin to like each other. find something your yorkie loves to do and do that with both yorkies. what worked best for our problem was that his dog bambi loved to play fetch. so we started playing fetch a lot with the 2 of them. then it took her mind off that there was a new dog and started to think it was a fun game. now they are good friends and can sleep next to each othe and share food... i thought that day would never come, but it did. it took a few months though.
dont give up. your baby is stressed initially, but she will learn to love her new friend. ive read one boy and one girl are easier to make friends than two girls. mine were both girls btw... heres a pic of our pups, now best friends.
