My puppy is still sick and won't eat after vet visit, what's wrong?
Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Hercules. Sounds like you need to have him evaluated again by your vet. Just wondering if any blood work was done and if not I would advise getting some done to evaluate his overall health and internal organ function. Possibilities include intestinal parasites (roundworms, hookworms, whipworms, giardia, coccidia, etc), dietary indiscretion (eating things dogs are not supposed to eat), dietary/nutritional problem, infection/inflammation, foreign body ingestion, toxin exposure, other gastrointestinal diseases, disease in organs outside of the gastrointestinal tract (pancreatitis, kidney/liver disease, etc), among many other causes. The fact that he won't eat is significant since he will get weak and possibly dehydrated also if he is not drinking fluids. Your vet can reevaluate him and see if anything has changed on physical exam and then propose other tests if needed. Good luck with Hercules. I hope he feels better soon.
