How do you fix dogs titts after having puppies?

Your dogs breasts will be enlarged and full of milk for her puppies. You don't 'fix' them, the puppies should be feeding of her until they're 3-5 weeks old, which is when you should start weaning them onto puppy food. You need to wean them gradually so that the bitches milk ducts don't become swollen and hard, sometimes an overflow of milk in the breasts make them detach and become quite hard this is when there is too much milk and you may need to milk them down your self by gently queezing the excess milk away.
