Early neutering/spaying started a while back only as a means to control pet overpopulation. Prior to that change, it was done after the first heat or when a dog became sexually mature. When neutering/spaying is done, it immediately turns off the hormones in the dog's body, and the hormones are responsible for many, many things that go on during growth. It is also important that it not be done until the pup's growth plates have closed, especially if the pup will be taught any type of agility training or similar activity.
Just because it's being done doesn't mean it's the heathiest thing to do. |
