Why is my puppy exhausted with bloody diarrhea and trouble breathing?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 5 lbs

Im fostering two pups and one has symptoms which in the beginning included almost liquid poop and blood in his poop. We took him to the vet and they tested him for parovirus but it came back negative so they gave us some antibiotics to give him because they suspect he may have worms. However I have been noticing so troubling signs from him, such as he is constantly exhausted, he seems to have trouble breathung and a very intense stomach contraction when he tries to breath. please let me know!!!

Having severe diarrhea like Beckett seems to be having can be very painful and uncomfortable. This may be why he is more lethargic than normal and why his stomach seems tense/contracted. It is great news that he doesn't have Parvo! Hopefully in addition to the antibiotics your vet also dewormed Beckett, as puppies often have intestinal parasites. If Beckett stops eating, begins vomiting, or the diarrhea isn't improving after about 48 hours of being on the medication I would recommend bringing him back to the vet to be reevaluated. Sometimes with severe diarrhea these little puppies can become dehydrated and need additional treatment like fluid therapy. Good luck!
