With regard to our new male dog (who in case you haven't read his thread is a 2 year old Japanese Mastiff x Bulldog).

I believe he should be neutered. I've always kept dogs that were spayed or neutered and feel it makes for a better pet. Also I think this dog will be an even more balanced, attentive home protection animal if he is not stressed by the drive to breed.

My husband on the other hand, while agreeing somewhat with me, is concerned it will make this male dog lazy and less alert. Mike is also concerned with how hard this might be on a fully mature male dog. I'm not sure on this point since all my previous dogs were fixed as puppies.

So what's your opinion. I have a call into the vet clinic to book his neutering and would like to put my husband's worries to rest about this procedure. I'm especially interested in those of you that do own some of the stronger natured, protective breeds. Did you get your male dogs altered? If so did you see any major change in how they help you care for your home's security?
