I obtained my first pedigreed cat in 1970 and have never looked back. In 1971, I obtained my first Abyssinian which has become my primary breed. In addition, I have bred Manx and Persians. Currently, besides the Abyssinians, I am also breeding Maine Coons.
1 Recently, the American Veterinary Medical Association endorsed Early Age Neutering, which can be done as early as two months or two pounds, but the average age is four months. 2  There may also be laws in your area that require your dog to be spayed or neutered by a certain age.
In order to ascertain for sure when it is safe to neuter, it is best to wait until your dog is at least six months old, and for larger breeds and those that grow and develop more slowly, possibly several months longer.
