My wife and I are contemplating retirement this year after working for 46 years. We have a large, beautiful home where we raised two kids. Our daughter bought a pit bull puppy years ago while living with friends. Then she had a kid and the dog eventually moved in with my wife and I. She stayed with her friends and married the father of her child. They stay in an apartment. We've had Cassius for 4 years and he now weights 100 pounds. I've fallen several times at our house on the stairs so we're looking for a smaller, one story place or apartment. Apartments are difficult to find with big dogs. As time went on, Cassius gradually got closer to my wife and I. He doesn't seem connected to my daugher. He's a wonderful dog, friendly to people and loves to go for walks. However, he's a tough looking pit bull. Everybody who sees him comments on his large, muscular build. I'm really torn about what to do at this point. How difficult would it be to find another owner for a big dog who is 5 years old?
