Hi Kathleen, Some boys are wimpy after neutering and maybe experience some soreness. While providing him with TLC don't baby him too much, let him rest in quiet and take him for a little leash walk in the garden a few times so he doesn't stiffen up. He may or may not swell a little and if needs be he might appreciate the support a pair of boy's Y-Fronts, just turn them backwards so his tail comes out the Y, this will also help protect his incision. If you notice his incision looking red and angry looking then check in with your vet in case of infection, monitor his temperature (normal is 38.5C) and it may be slightly elevated due to discomfort if it goes too high then again check in with your vet. Do not give him any ASA compound as that encourages bleeding but you might get an alternative painkiller from your vet. Allow him a couple of days to get over the anaesthesia and stress of surgery and keep him leashed for at least ten days and then no rough housing for a while.
