Rescued a black lab female from the shelter a month ago, turned out she was pregnant. She's estimated 60 days, She's had milk for two weeks, I'm afraid mastitis may be developing as one of her teets feels hard. This isn't our first dog pregnancy. I've taken her temp everyday twice a day and its getting lower, 99 this morn. I'm hoping puppies will come, nurse and mastitis won't be a issue. Is there anything I can do to speed her pregnancy along?
