We bought a dog that I believe is a Rottweiler mix. He is about 1 1/2 years old, fixed, and he is a very sweet dog. I would truly love to keep him, and this is not something I want to do, but unfortunately my 5-year-old pit mix is not handling another large male dog very well. After trying to make it work, I honestly do not think the situation is going to work out good and I do not want anything to happen to either dog. The dog is good around people and my kids, seems to be potty trained, hasnt had any accidents and lets me know when he wants to go out, he does have a lot of energy. Unfortunately, I do not know his vaccination history.
