Re: what age did your femail go into heat
As a vet tech, we hold to the general suggestion that you spay at 6 months. This is because the "average" pet owner isn't up to dealing with the heat cycle. It can be messy, and it's amazing how many male dogs end up showing themselves when they think the time is right.
On that note, if the owners are compentant, it is now belived that allowing a dog to reach sexual maturity is better for their growth, especially in large breed dogs. If you leave them intact, they tend to grow slower, and form a bit more muscle.
I own a pet Gsd with an ortho problem. After discussing it over with several specialist in my field, I have decided to let him remain intact until he is at least 2, so that his muscles and body can develope fully.
If he was sound, I might have neutered him already.
