I have an 11 yr old lab/pointer that i rescued for my son when he was 10. She slept with him every night and grew up with him and 3 other dogs that were my other kids. I have several problems with her now. MY son joined the marines so she is here with us now and my other kids grew up and I have all 4 dogs. She wants nothing to do with the other dogs and it has gotten so bad we have to keep her completely separate. The 2nd issue is we do foster care and she all of sudden doesn't like little kids and tries to nip at them so we have to keep her away from them. The 3rd problem is she has developed horrible sleep habits. One night she will refuse to sleep alone, the next night she will want to go outside every few minutes for no reason just to want to come back in and will want to move all over the place. MY wife and I are beside ourselves with what to do with her. Please help?
