We thought it was a bit of dominance playing with the new dog but today we let them off the lead and the new dog had bitten my dog and pinned her down and was going some every day he seems to get more aggressive toward any other dog... we are worried.
Thanks

I can honestly say that the new dog is fine. no injury...my dog is soft and tries to take things to play with him and he just grabs it tosses it aside and pins her down...it is bad in the house but it was uncontrollable in the park and my dog is looking very unhappy...she already has bite marks being treated at the vet.
