The symptoms of acid reflux in dogs are similar to those of other gastrointestinal illnesses, so it is important to take your dog to the vet if he exhibits any signs of a digestive disorder. Dogs with acid reflux may only show mild symptoms if they are moderately affected, and more serious signs if the lining of their esophagus is severely inflamed.

gastroesophageal reflux
GERD, often referred to as GERD, is the equivalent of acid reflux in people. GERD results from the uncontrolled flow — in the opposite direction — of intestinal fluids or gastric juices into the esophagus. The esophagus is a tube that carries solids and liquids from the throat to the stomach. Harsh gastric juices, including febrile salt and bile salt, can eventually weaken the protective lining of the esophagus, leading to inflammation and pain. While GERD occurs more often in young dogs, all dogs are at risk.
Vomiting versus regurgitation
While the primary symptom of acid reflux involves vomiting, it is regurgitation of food rather than regurgitation. Since the dog’s action is similar to each other in either case, you should examine the outcome or watch the dog carefully when he eliminates. Regurgitation usually occurs suddenly, without warning. It is generally much faster than vomiting. With vomiting, the dog often appears beforehand, and you’ll see him breathing much more actively. Undigested matter is undigested, and looks like food that a dog would consume after chewing. Vomit, which consists of the dog’s stomach contents, is shown to be partially digested. If it contains bile juice, and is characterized by a yellow liquid, it is almost certainly vomiting.
Other symptoms
In addition, signs of canine acid reflux include appetite and subsequent weight loss. Your dog may experience pain while swallowing, so he whines or looks uncomfortable while eating. Gastrointestinal lethargy and noises can indicate GERD. Dogs with severe cases of GERD may salivate excessively and run a fever.
Diagnosis and treatment
If possible, take a picture of the contents of a recent canine upset to help your vet determine whether your pet is vomiting or vomiting. For a clear diagnosis, your vet will likely perform an esophagoscopy, or use a small camera to view your dog’s esophagus. Pictures show whether or not the lining of the esophagus is damaged, the clearest evidence of GERD. Treatment may include feeding and feeding schedule changes. Your vet may recommend low-protein, low-fat foods fed several times daily, rather than in one or two meals. They may also prescribe medication to improve the flow of stomach content.
