Unless you are planning to breed your female dog, it is not a question whether you should spay her or not. Beyond saving you from unwanted litters, spaying your female dog is proven to decrease the chances of developing mammary cancer and other lethal diseases as this article points out.
The question is rather when is the best time to spay your dog? According to the above mentioned article and most veterinarians, the answer is before sexual maturity. It is easy to admit that if your dog is spayed before her first heat cycle (usually 6 months of age), the chances of accidental pregnancy and unwanted litters are zero, which is great, because the problem of overpopulation shouldn’t be ignored by any responsible pet owner. So the simple answer may seem to be: the sooner the better.
“Would castration solve the behavioral problems of my dog? Would it stop the wandering? Would it solve the problem of urine marking? Is it a struggle? Will my dog gain weight after the surgery? Would it reduce its protection ability? What other solutions are there for making my dog infertile?”
Just a few of the frequently asked Questions about neutering male dogs. Although the topic is quite controversial, there are some proven facts that I would like to share a few thoughts about to help you in making this important decision. Let’s see the most common believes and the truth.
Belief #1: Castration will reduce the aggression level of my dog.
Well, in some cases, yes. But only if the dog is trained well. If your dog shows aggression towards people or other dogs due to the lack of training and care, castration is not going to solve the problem. But in most cases it can reduce the sex-related aggression, thanks to the decrease of the hormone level.
