I got my first yorkie in August. He is now 5 months old. Right now, my boyfriend's border collie is staying with us. Shes been here the entire time we've had my yorkie. Riley and Shady play everyday and they are so happy. The only problem is Shady is going back to my boyfriend's parents. She was only staying here for a few months. I'm worried about Riley getting lonely, especially since my boyfriend and I both work and go to school. I thought about getting a new Yorkie around March, but I'm not sure if thats too early since Riley won't even be a year old yet.
