WOW! Congratulations on the large litter and wishes of continued good health to them all. Mama's poor belly looks so uncomfortable with the mastitis; my female had just a slight problem with that on her two highest nipples that were not being used when she had her pups. But yes, with the cold compress, just very periodically, it was gone in no time at all.
I'm anxious to stay updated with pics of 7 growing puppies, so keep 'em coming!
