My puppy is still sick and won't eat after vet visit, what's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkipoo | Male | unneutered | 5 months and 8 days old | 6 lbs

My 5 month old Morkie threw up Tuesday & Wednesday, he’s very lethargic. I took him to the vet. She did an X-ray, and found no blockage or significant gas. She gave him an injection to help with vomiting & recommended a bland diet. I can’t get him to eat anything. He’s still lethargic, and seems sad. Any suggestions?

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.

    Poor Hercules! If he's been home for a day and a half now and is not doing any better, I would recommend taking him in for a recheck. It sounds like he may need some additional diagnostic testing to help determine what's wrong. I would likely suggest starting with general blood work, a parvo test, and an abdominal ultrasound if these things have not been done yet.

    I don't understand how you went to the vet and were sent home with no help. Is that because you declined a work-up or because the vet was really no help? If the vet was really no help then you should take Zeus to a different vet. This is serious and he needs to have a work-up so he can get the appropriate treatment. Vomiting and lethargy are not specific symptoms for any one illness or disease process. Testing is needed to find out what the problem is. If he is still sick he needs to go back to the vet. I would be concerned about a gastrointestinal obstruction which is not going to correct without treatment.
