Will neutering my 4-yr.old Great Dane help alleviate his new behavior of alpha dog aggression?
Most likely not. The only time neutering affect behavior is when the behavior is hormone driven. If there was a female in season around then I’d say yes, if there wasn’t a female in season around then no. From what you have said it seems much more likely that the change in behavior was somehow driven by your recent move…it is possible that there is a female in season that you don’t know about and he is smelling that and it is the basis for his aggressive behavior but I doubt that is the really problem or you would see fights at every show. If you want to neuter him it won’t harm him I just don’t think it will cure your problem and before considering neutering you should discuss the matter with his breeder so that they don’t decide to harm you for breach of contract….if you offer to have him collected and make the frozen semen available to them they will most likely be agreeable.
