Cookie gets along well with Odie. Odie is calm and submissive. Cookie can not stand dogs who challenge her alpha status. Cookie has to be number ONE. Dodo wants to challenge Cookie, and Cookie wants to eat Dodo. Cookie plays rough with Momo and Momo is submissive.
So far Cookie only allows me to dominate her while she lies on her back and belly up during our play time. Cookie never submit and belly up for any other dogs, ever!
