What a tough decision to be in...but ultimatly you have to do what is right for the dogs. It isn't fair to keep on dog in jepordary and sometimes rehoming is the right answer.

I was just talking to a friend yesterday about a friend of hers that had 3 dals. All 3 gre up together and got along for many years. Suddenly the no longer did. They tried behavorits, etc, etc, but ultimately had to split the dogs up.
