I didn'get my GSD until he was 8 months old. He absolutely saw my cats as prey &'would have killed them if my husband and I hadn't had him on a leash and even then he almost pulled our arms off. We have a trainer & work with our dog daily but as soon as the trainer was gone Max would be back in cat killing mode. We did use a prong collar. It was a bust.
With our trainer showing us how to use it we switched to an e-collar. Max was cured in one afternoon. Our cats can be out where he is and even run in front of him. He doesn't even look at them. I'd still never leave Max alone with the cats but we can all roam around the house free and I'm comfortable that Max isn't going to kill the cats as long as he knows I'm in the house.
