A few of my dogs newborn puppies have blisters on their stomachs. They started out small, they were red. Now they're bigger and some of them look like they have maybe busted. The tops of those are now a greenish yellow color. Can someone please tell me what this might be. And how to treat it.
The blister on the belly is probably unrelated to a bloody stool. However, either are normal. Please take a stool sample to the vet because many parasites can cause bloody stool, such as coccidia and giardia. You should also have the "blister"examined.
