Why does my dog keep throwing up hours after eating for weeks?

Updated On September 23rd, 2025

Pet's info: Dog | Doberman Pinscher | Male | unneutered | 2 years and 3 months old | 30 lbs

Hi, My dog keeps being sick 1 1/2 to 2 1/2 hours after meals... Tried boiled chicken and rice, but he's still being sick... This has been going on for 8 weeks... He's not regurgitating, he's vomiting... He's had an anti vomit injection, but it didn't work... X rays didn't show anything, other than gas... Could he have an infection? Thanks

Hi, sorry to hear your dog is having this problem. I would recommend an ultrasound to make sure he does not have Inflammatory bowel disorder or a foreign body that does not show up on x ray. Some foreign objects can migrate throughout the GI tract so they can sometimes cause problems and sometimes be fine. An infection would not cause this problem. The anti vomiting injection only lasts 24 hours so if he did not vomit on that, you can try oral tablet of it. But if he did vomit through the injection, it is more likely he has a foreign body. If your vet cannot do an abdominal ultrasound, I would go to a specialist who has an ultrasound and is good at them to find out what is wrong Good luck, I hope this helps!

    Poor Erik! What a frustrating problem. An infection could certainly be possible. Some other possible causes would include a foreign body causing a partial GI obstruction, gastric ulcers, a food allergy or intolerance to something in his diet, a systemic illness like liver or kidney disease, or even a tumor in the stomach. I'm not sure if any diagnostic testing has been done apart from x-rays, but some tests that may be helpful at this point would include general blood work (CBC/chemistry panel), abdominal ultrasound, endoscopy, or even exploratory surgery. I would suggest talking with your veterinarian about these options, to see what he/she recommends as the next step for Erik from here. You could also request referral to an internal medicine specialist for further work-up, if needed.
