I noticed my Doberman trying to mate my female pitbull, but she has been bred, and I thought she was no longer in heat. If the Doberman gets to the female, can he breed with her even if she has already been bred?

Answer

If your Doberman mates with your Pitbull, you might end up with a litter of mixed pups; some will have one father, some another. This is common in street dogs where breeding is not controlled. The best thing you can do is keep them separated until the female will no longer allow the male to mate.
