My boy was neutered in June of this year and it was pretty easy going, just make sure he doesn't get his sutures wet. Also I was told not to let him be real active such as running and jumping around for a few days. Other than that I don't know of anything specific to tell you other than to watch for inflamation around the incision. I am sure the vets office will tell you everything you need to know. It seemed like a breeze for Nash. Neutering isn't as invasive as a spay is for a female so males seem to get over it much quicker.
Coco was sooooo annoying when he got neutered! he kept INSISTING to lick his stitches...even with the E collar on! Duchess was an angel and could care less about them. lol just keep an eye on him...make sure he relaxes and doesnt lick or chew on them.
