I recently got a 2nd yorkie male, he was 10mo when I got him and although I paid decent $ on him the lady lied to me about many things- so he needed extra tlc like a somewhat rescue yorkie would need. I don't really regret getting him, I just wish I would have known that he needed alot of TLC and rehabilitation on behavioral probs but other than that, Lucy gets along great with him and she is definately the apple of his eye. He loves her and has adjusted to us gals very well. It is somewhat different if you are getting a new pup though I think..but I do have 2 and it really isn't any harder than having one. We still have the same routines..like potty together in the morn, going together in the car and bathing on same days. The only thing I notice is sometimes I will feel bad having them take turns if I do not take them together on everything like a walk with a stroller and 2 dogs without a coupler yet. It is just that Milo is not as well behaved as Lucy is..but they both get equal turns.
