Neutering your dog is helpful in getting your male dog to control certain behaviours that are usually seen as unpleasant. It is also necessary to control the pet overpopulation problem that leads to many animals being euthanized in dog pounds every year. Even though neutering is a minor surgery, it is still surgery and it causes a moderate amount of pain for your dog. There are ways that owners can reduce the amount of pain their dogs experience during recovery.
Speak to your veterinarian about pain medication. Your vet can prescribe a number of pain medications, such as Torbugesic or Rimadyl, that will help ease your dog's discomfort after the procedure.
Keep the dog in a crate as much as possible. This will reduce the amount of movement that your dog makes, lowering the chance that he will tear or irritate his sutures.
Purchase a cone for your dog if he chews or licks his stitches excessively. This will reduce the amount of pain he feels and keep him from increasing the length of his rehabilitation.
