I rescued a dog from the shelter almost two years ago. He was just a pup and we were not sure what he was. We no there is definitely some pointer because he is tall, slim, has black spots on legs and back and points at birds but as he matures he looks more and more like a rottweiler. He lives with my grandparents and they are conserned. My grandmother is scared of pitt bulls, german shepherds and rotties. When she was a child they had a horrible reputation. He also is showing aggresion towards my uncle who lives with my grandparents and he got snapped the other day. I was wondering if you could tell me how to handle this dog since I never owned a rottie mix before. I'm scared that we won't train him correctly and he will become wicked. Please tell me how to handle this dog and how to avoid aggresion. I love the breed and I believe there are not bad dogs just bad owners. Please help me.
