i had to ween the puppies at three and half weeks .i am having problems with the mothers breast ,they are hugh please help ! pups have been off two days.
Take the mother to a vet. They can prescribe pills or give her an injection to dry up her milk. Do it straight away as she will get very uncomfortable indeed.
and in the meantime...be careful that she doesn't feed the pups as it sounds like she has mastitis (an infection) in her milk ducts. If she has pus & infection in her milk, you don't want the pups to drink it.
