Always take your pets to a veterinarian when concerned for their health. Here's a video on how to take care of newborn puppies https://www.youtube.com/watch?v=tHpnzOXcAIE.
Hi Jocy 😁 If you still need help let me know. Are you in the San Antonio area?
Take both of them back and have their vet check them out.
I do know that you can use can baby formula. Get the one for new borns
In this case, always consult with a veterinarian. Never used cow's milk based formula. https://pets.webmd.com/dogs/guide/caring-newborn-puppy
Take the puppy to the vet to see what's wrong.
