I agree, Mazi's mammary glands do look quite swollen. This can be a sign of mastitis, which is an infection of the mammary glands. Mastitis is very serious. I would take her into a vet asap to get this checked out. As for bottle feeding the puppies, weigh them daily and if they aren't gaining weight, they do need to be bottle fed. The vet can advise on this as well. I hope this helps!

    The swelling of the mammary glands will go down on their own. It is recommended that you don't do anything. This is a normal process. If she still had the puppies eventually they would not be nursing anymore and her milk would dry up on it's own. Same in this scenario. Now, if the glands are infected that is different. If you are not sure if it is normal or infected then please post again with some photos and we can maybe help you better.

    These signs could be due to a mammary gland infection (mastitis). A clinical examination at your local veterinarian is essential to confirm this clinical suspicion and treat appropriately. Antibiotics may be needed.
