My puppy has bloody diarrhea but acts normal. Could it be parvo?

Pet's info: Dog | German Shepherd | Male | unneutered | 2 months and 3 days old | 20 lbs

My dog has has diarrhea for three days now. There was some blood in his poop the first two days and it was watery but there has been no more blood after the second day. He acts playful and normal and drinks lots of water and food himself. If it were parvo, would other signs have been showing by now? I’m worried because my older dogs have also been hanging around him.

Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. Yes, other signs typically would be present with parvo such as vomiting, lethargy and inappetence though in theory it could still be parvo. I recommend that you have Shaggy evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea depending on the results. Good luck! Hoping for a speedy recovery!
