My 11-week-old puppy has diarrhea but is still playing and eating.
Thanks for the question. I'm glad to hear that Fenris is still playing and eating, but I am concerned that the stool is so watery. Yes, it is always possible that this is just a dietary issue, however because it has been going on for 4 days, and is so watery, I'm concerned that this is something infectious. At 11 weeks my main concern is parvovirus, however most of these pups act really sick, but it is still possible. Other possibilities are things like giardia, coccidia, or a viral infection. I recommend collecting a sample of the diarrhea in a bag or container and bringing it to a veterinarian for testing. They will be able to determine if there is a specific medication that is needed to fix the problem. Puppies this age don't have a lot of reserves, and can become dehydrated quickly. I'm happy that Fenris seems to be otherwise feeling okay so far, but I would feel better getting the diarrhea under control before it becomes a more serious problem. I hope Fenris is back to normal soon.
