Puppies should be neutered between 6 and 10 weeks of age. If your male dog is over 4 months old, it may be too late to neuter him without special consideration. Some veterinarians will perform a vasectomy (which can also be performed on females) for males at this point in time; others will simply spay them if they are not already neutered.
What happens during surgery? How do I prepare my pet? What’s aftercare like? Will anything hurt my pup?”
