Had to do the same back in December with my Invicto II bitch. She came down with milk fever, took the babies off of her so she could stabilize, took her to work with me so I could keep an eye on her and even with me applying cold compresses to her teats to try and prevent the let down of more milk, she developed mastitis in literally under five hours. Sigh. Clavamox + hot compresses, and she was healed up in a couple of days. I had actually taken pictures of the before and after and was going to make a post about how to handle ruptured mammary glands, but you beat me to it with your article on hot compresses, haha.
