answered question 2/28/2010 What Can You Feed A One Month Old Puppy If Momma Dog Won't Nurse Pups Very Much Since She Is Getting Cut Up And Scratched Too Often? The best thing to do is get puppy sized dog food. I prefer Purina. Put it in a small deep plate and fill it with water and let it sit for a minute. It's soft and wont hurt the puppies teeth. Trust me, ive raised 7 litters of puppies.
