Just from reading the previous points i would say its not even a question. I can tell you, we too considered not having our boy neutered thinking we might breed him. He was an adorable puppy and every time we went to the park people would comment. We decided to get it done, our vets office encouraged it and offered this "first year of life" program which included the alteration at a discount. At about a year old our boxers face started changing, very slowly. Now at 2.5 years old its very obvious his jaw is deformed. We found out its wry jaw (also known as wry mouth) and basically what happened was his jaw began to twist as he grew. Dogs that have this should never be bred, and apparently his parents should have never been bred either because most likely one of them had it as well. Now we're faced with more problems that we just found out about Tuesday night. These issues all stem from poor breeding. Bottom line is we didnt know these things when our dog was a puppy, so unless your like an expert...you really really dont know what your doing.
