Hello, this is my first post and I need some advice. I have a healthy Doberman female that will turn 8 this June. We have never bread her but after much consideration we want her to experience being a mother at least once. (And you know, she's still a virgin.....) But we worry we have waited too long. I have read some people suggest stop breeding at 6 or 7 bit I wondered if the fact she has never had a litter would make it safer or more dangerous.
