Just like humans, dogs are susceptible to acid reflux, a condition where stomach acid and sometimes bile back up into the esophagus. However, if your dog is foaming at the mouth, another condition is most likely causing it.

Significance
-
According to the Pet MD website, acid reflux is a common condition in dogs. While it usually occurs in younger dogs, it can affect canines of any age. The condition occurs when the sphincter muscle at the top of the stomach relaxes and allows gastric juices into the esophagus.
Identification
-
Symptoms of acid reflux will vary based on the severity of the condition. Symptoms include vomiting, weight loss, disinterest in food and pain when swallowing.
Considerations
-
Foaming at the mouth is not considered a key symptom of acid reflux but it is possible. According to the Vet Info website, foaming is usually a sign of exertion or if the dog gets a bad taste in its mouth. However, dogs that have problems swallowing, a sign of acid reflux, can foam at the mouth.
Causes
-
Acid reflux is usually caused by a congenital condition like a hiatal hernia. If your dog recently had surgery, anesthesia could also cause the stomach sphincter to relax.
Potential
-
If your dog has acid reflux, your veterinarian will likely prescribe a low protein and low fat diet to give your dog. If the reflux is severe, your veterinarian may also prescribe medicine to block the production of stomach acid.
