My husband and I are thinking about adding a new yorkie baby to our family. We have a few concerns though. Butters is 1 1/2. If we got another puppy would it effect Butters personality? Do they tend to get jealous? We have a Great Dane and we got him when butters was about 4 months. They have always gotten along great and there has never been any jealousy problems. I would just like some input. Butters has the best personality of any dog I have ever seen and I would hate to see that change.
