Princess is a rescued rottweiler and our cat, Crellie, is a rescued cat. Somehow Crellie seems to understand that I want her and Princess to be friends. Crellie is declawed so she has no defence against an 88-pound rottie. She will lie down and roll over onto her back to show submissiveness to the dog. When she is standing, the dog pushes her with her nose. I think Princess hopes the cat will run, then she would chase her and probably kill her. I cannot let them be alone unsupervised.
