Should breastfeeding continue if dog is sick?

And what will happen to the puppies if they continue to nurse in there mom? The mother dog vomit.

That won’t pass through the breast milk.
They would get sick if she had something contagious and ate the vomit.
If you don’t let them nurse then they will definetly get sick.

*However this is assuming your dog has had a Parvo shot. That is contagious no matter what and usually fatal*
