Hello. My wife and I currently have a 1.5 year old black lab. We have had him since puppy. He is the sweetest and most loving dog ever as I'm sure all lab owners can attest to. He loves attention, sleeps with us, sits on the couch with us and is very well trained. My 12 year old daughter has us considering rescuing a second dog. We obviously can manage and accommodate. My question is. What are your opinions about how our one black lab whose is used to having. All the attention will manage.
