Poor Noah! Puppies can get blood in their poop for a number of reasons but the most common causes are from infection (like parvovirus) and intestinal parasites. Noah should be seen by a veterinarian right away as that is a lot of blood in his stool. I'm concerned that he needs to be tested for parvovirus and intestinal parasites. Puppies can easily get very sick very quickly so the sooner he receives treatment the better chance for a good outcome for Noah. Left untreated he may become dehydrated or anemic so again, the sooner he receives veterinary care the better. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Noah is feeling better soon!
