That question is answered differently by many people. It is universally recommended to wait until at least the second heat cycle, and after they are a year old. The American Boxer Club recommends that you wait until your female is 2 or older. Boxers, as with all large breed dogs, don't age as fast as smaller breeds. They are not considered adult until they are 2. It is every breeders discretion, as to when they choose to start breeding their female, but I recommend waiting as long as you can. I didn't breed mine until she was over 2. I hope this helps. Good luck!
