Why is my dog with megaesophagus still vomiting and not eating?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered | 70 lbs

Hi, My 4 yr old labrador is not taking up any food for a week and also vomits thick white foam. We did some blood tests as advised by vet and it seems like he's suffering from megaesophagus. Unfortunately there's no place near us to take an X ray. Also I doubt if he had some plastic/pebble/or something in his stomach. For the last three days we been giving him IV drip. Still no progress and he's not taking any food. B/w we tried giving food in elevated position but still throwing up. Pls help.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. I am sorry that Rambo isn't feeling well. Mega-esophagus is a very tricky disorder. Mega-esophagus can be caused by various underlying diseases including cancers, hypothyroidism, myasthenia gravis, and other conditions. I would discuss with your vet about testing for these, as some are treatable. Mega-esophagus can also be primary, or just aquired. In this case there isn't much treatment, just management. Management involves feeding meat-ball shaped foods from an elevated position, and water being up in an elevated position. It is also important to monitor for signs of aspiration pneumonia (food going into the lungs), as this is a common complication that occurs, and can lead to life-threatening pneumonia. If aspiration pneumonia is suspected then antibiotics are sometimes required. Management of this condition can be very difficult and tricky, and will require a good relationship and unfortunately frequent relationship with your vet. Other medications to help or consider include proton pump inhibitors (omeprazole), anti-nausea medications (maropitant, ondansetron), pro-kinetic medications (metoclopramide). Talk to your vet about these classes of medications. I hope Rambo feels better soon.
