Yesterday my two new 7 week old puppies started vomiting watery looking foam stuff and pooping blood. They have lost a lot of weight since yesterday and will not eat. They are drinking water though but not a whole lot. I wormed the less then a week ago. Please help me. I don't know what's wrong...

Watery vomit and pooping blood, you need to get them to the vet right now! Time is not on your side, this sounds like parvo! I can only guess, but, if it's parvo you don't have much time, it's deadly and even when caught early isn't always treatable. Please, vet, 5 minutes ago!

It couls potentially be the deadly parvo virus, and if so your puppies are on borrowed time. You need to get them to the vet ASAP or you could lose them both.
