My dog is very sick, multiple vets have no diagnosis. What's next?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 4 years and 3 months old | 70 lbs

My dog has had bloody diarrhea for 3 weeks. He's taken flagyl for enteritis which was helping. He now has fluid in his abdomen, weight loss, diarrhea is worse, fever,and lethargy. Bloodwork shows liver and kidneys are fine. Ultrasound and X-ray showed nothing. Fluid was drawn from abdomen and sent to pathologist. Waiting on results for that. My dog may have had a seizure earlier today. We've been to 3 vets and gotten no answers yet. I'm really concerned and desperately seeking any help.

I'm sorry to hear about all that's been going on with Harper! That's frustrating to see your dog feeling so ill and not be able to get a concrete answer. Has your vet discussed the option of referral to a specialist? It sounds like your vet has been very thorough - I would consider the option of seeing someone boarded in internal medicine. Specialists are typically available through university teaching hospitals, but many specialists work in private practice as well. Your vet should be able to help you find the nearest internist. That would be your best bet to try to reach a diagnosis. Not only do specialists often have access to advanced diagnostics that general practice vets may not have, but specialists will also be most knowledgeable when it comes to the rare conditions that a private practice vet may only see once or twice in their career. I'm sorry I'm not able to give you a better idea of what's going on with Harper - but after seeing 3 vets, hopefully this helps provide you with some direction of where to go next.
