Work them Pet Bulls!
Sounds like they love rough housing but it's to much for you not them?? Am I right? :roll: I would take them out for some good walks to tire them out a bit so that they are not so wild in the house. Also, do you crate them at all? I know you take care of Cain for the owner when he works long hours but does your dog and Cain have there own crates? I would separate them when they get to crazy with eachother.
