Rottweiler, German shepherd, pitbull, bulldog???? Of course your dogs are growling and fighting. Why are you picking aggressive breeds? Sometimes a dog can be sweet and be a rottweiler or pitbull, but you are rolling the dice. If all you choose are aggressive breeds, you're loading the dice.

Choose a nice, cute beagle. How about a St. Bernard, or a collie. A Labrador retriever? Or, how about a collie/shepherd mix. Get a nice mixed breed with maybe a little rottweiler in it. Why though? I've had mixes that were part shepherd and they work out find. I'd never adopt a pure shepherd, rottweiler, bulldog, pitbull. Love dogs but don't need that time bomb in my house.
