How old dose a male pit-bull have to be before I breed him?

You'll probably get alot of these type answers. First off, if you dont know how old a dog needs to be, then you have no business breeding. Next, if your friends want a dog they should go to a shelter. Plenty of dogs being put to sleep with absoluty nothing wrong with them. All your going to do is add to that population. If you love your dog like a child, then you would never want to see any of her children be put to sleep, so why take that risk??
