Thanks everyone. She is a joy. Mamagus are your dogs all males or something? I thought about a male pup because Tank is such an awesome boy but didn't want 2 males together.
Tank does fine with other males that come to visit but he knows they are here to only visit. When Heidi was here she
was older than Tank so she let him know who was top dog right off. I think Tank is going to like being top dog now. He did like being the only child too though. Just more spoiling. :-D
