I will be moving with my father until i can get on my feet and get a place of my own. he has a intact male rott, female rott/beagle cross, a female chow/wolf hybrid, and a female giant schnauzer puppy. Ruckus has played with the male rott, no problems there. and the female rott mix is VERY old. The wolf hybrid barks at Ruckus then pretty well ignores him. and he has never met the puppy. Ruckus plays rough. he pinches, shows teeth, jumps off of other dogs, and runs around like a mad man. i am scared of him doing this with so many new dogs around. shouldnt i keep him on leash until the dogs get to know him, and of course always supervise? any tip?
