My Shepherds saw my cat in her crate when we brought her home from the vet and wowie they went nuts!! Spice cut her mouth but seems to be fine now. They knocked out a piece of wall trying tp get at her and my mom thinks they are really screwed up. She said they are vicious. I think it's instinct since they weren't raised with her. She lives inside, the live outside. They wouldn't listen to us they were jumping and trying to bite through the cage although I don't believe they were trying to bite us. We got in between it and are all scratched up. Anyone have any ideas on how to prevent this kind of thing happening? and also if we got a new dog would they react the same way?
