My puppy has chronic diarrhea and vomiting. What could it be?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 5 months and 4 days old | 43 lbs

Long story short two months, an unnecessary surgery, and $1400 later, my puppy isn't any better. Diahrrea or loose stool for 2 months. Tested for worms 3 times and parvo. Diahrrea and vomiting for 3 days. 2 xrays. Vet said something was probably in his stomach. Had surgery, but nothing was there. A thick stomach lining, fluid, gas, and an atrophied pancreas. No diagnosis. I thought EPI but feeling better on prescription food without enzymes. Now thinking pancreatitis. German shepherd and pointer

I am sorry that Cable is not well. I know you are frustrated but please keep in mind that all animals "read the book" so sometimes treatment and testing are not straight forward. Just like in human medicine. During the surgery did the vet take any biopsies of the inside of the intestines? That would have been good to do to check for inflammatory bowel disease as well as some other bowel disorders. EPI is a possibility although he is a bit young to already be showing symptoms. Simple blood and fecal tests can accurately detect if the condition is present. Canine trypsinogen-like immunoassay (cTLI) is the preferred diagnostic test for EPI. cTLI in combination with Vitamin B12 and folate level tests give us the best assessment of pancreatic function. So, if those have not been done I would suggest doing that. In the meantime I would do daily Fortiflora probiotic - one packet on food daily.

If you have more questions you can always opt for a private consultation where we can chat back and forth. That way you can ask as many questions as you'd like. Best wishes.
