It depends how old the puppy is. If your dog is 6 months to new born their stomachs are very fragile and can not handle it. They will usually barf. But if your dog is older it might just upset their stomach but you won't be able to tell.
When the puppies start eating solid food, they suckle less and the mother's milk will dry up.
the dogs puppies will be premature
Until they are about 6 months of age, then they can go onto adult food.
Get some dry dog food at the store that were made specially for puppies.
NOTHING
they die?
Food grade DE will not hurt puppies.
i usually feed them twice a day and i think they're pretty happy with that.
The mother might die unless the puppies are surgically removed.
yes they can
no
Standard dog food would be difficult for puppies to eat and digest but it is not 'bad' for them in the sense that it is poison.
