Hello Friends! My yellow black mouth cur had puppies 10 days ago and her breast are square shaped, extremely hard, and look very deformed. She is nursing her pups, eating, drinking, and none have any odd marks or obvious problems. They do get much softer and more normal after she nurses, but quickly go back to appearing square and problematic. Has anyone seen this or do you know what this is? If anything with her or the puppies seemed wrong I would take her to the vet. It's just very odd looking.
