I have a mini Doxie who will be 11 months old shortly. She is just finishing up her first heat which has been 3 weeks. Her nipples are still swoolen and her bottom as well, but not nearly as much. The blood is gone. I've been told that when they go "clear" that is when they are fertile. How much longer do I need to wait after the "clear" before she can play with her friends? Will her nipples go back to normal?
