Hand feed the puppy for a couple of weeks, then the puppy will be fine like its sister.
My 9 Day Old Yorkie Puppy Has Nasal Congestion After Aspirating Her Mother's Milk. What Can I Do To Help Her? Her Sister Is Fine.
If pups aspirate milk, it's in their lungs and they will get pneumonia and die. Get him to the vet immediately! The same thing happened to my shih-tzu and I lost him.
