While neutering a dog will have *some* behavioral effects, I would not rely on this procedure to magically 'calm' a dog. Farley is just as energetic as ever after being neutered. If you're having problems with your pup obeying you, take an obedience class, but don't assume that neutering will make him all of a sudden a different dog.
Boxers have alot of energy, and especially if your dog is a puppy, which I have to assume he is, he can't be expected to just lie around on the floor all the time!
