Symptoms and diagnosis of megaesophagus in dogs
Canine megaesophagus is a condition that can be confused with other digestive problems , so it's essential to recognize its characteristic signs. Identifying them early and seeing a veterinarian will make a difference in your dog's quality of life.
Most common symptoms of megaesophagus
Dogs with megaesophagus often present with a combination of the following symptoms:
Frequent regurgitation : food comes back up effortlessly, without gagging or abdominal contractions.
Weight loss : The dog is unable to absorb the necessary nutrients, even if it eats normally.
Respiratory problems : coughing, sneezing, or recurrent infections, often caused by inhaling food or liquids.
Hypersalivation and bad breath : due to the accumulation of food in the esophagus.
Apathy or weakness : consequence of malnutrition and lack of energy.
Difference between regurgitation and vomiting
This point is key, because many owners confuse both symptoms:
Regurgitation : occurs passively, without effort, and the food comes out almost intact.
Vomiting : accompanied by retching, abdominal contractions, and the food appears partially digested.
If your dog regurgitates frequently, it is a warning sign that requires veterinary examination.

Tests to diagnose megaesophagus
The veterinarian may recommend various tests to confirm the diagnosis:
Contrast (barium) X-ray : allows you to see the dilation of the esophagus and check whether food reaches the stomach.
Endoscopy : to directly observe the state of the esophagus.
Blood tests : help rule out associated diseases, such as myasthenia gravis or hypothyroidism.
These tests are essential to differentiate megaesophagus from other digestive or neurological problems.
When to go to the vet urgently
In addition to the usual symptoms, there are signs that require immediate veterinary attention:
Difficulty breathing.
Fever.
Persistent cough or runny nose.
These symptoms may indicate aspiration pneumonia, one of the most serious complications of megaesophagus, which can be life-threatening if not treated promptly.
