Spay & Neuter - Just Do It!
I strongly believe in the Save Lives! Spay and Neuter! programs. I have seen far too many unwanted animals come through shelters including lots of uncared for, unwanted, unsold, or accidental puppies. Therefore, I am only willing to train spayed and neutered animals or those under 6 to 8 months of age. They should be fixed by the time they have all of their adult teeth. There are only a few, mostly medical, or pure breed contract, reason that I will forgo my policy. If you choose to be a part of the pet overpopulation problem, then I simply don't want to be your trainer!
Some behavior problems can be attributed to animals being intact. Just like a teenager's hormones running amuck, dogs are strongly influenced by hormones. This can make them prone to wondering and sometimes aggression. I have heard far too many people say that their intact male is "a good dog, there's no reason to fix him" only to have him scale an 6 foot fence to get to an in heat female or two intact males getting into an altercation over territory or access to a female etc. I have heard of far too many cases when an owner is astonished as to how their female got pregnant when she never leaves the yard... and on it goes. This does not mean that fixed animals are perfect, but the odds are more in their favour.
In any case, until every shelter in the country that cares for stray animals is closed and unnecessary, population control is reason enough. Unless you are a professional breeder and your dog has no behavioral issues, you should not be breeding your dog. Not only are you contributing to the overpopulation of animals you may be putting your pet at risk if the pregnancy goes badly, which it can in young females. If you are a responsible, licensed, and registered breeder, you probably don't need my services anyway since you will be well versed in animal behaviour and obedience already.
Plus, please ensure your pets are licensed and registered per the municipal bylaws. For more information on spaying, neutering, and licensing, go to:
