What Are the Signs & Symptoms of Gastritis in Dogs?

One of the most common reasons for a visit to the veterinarian, gastritis is an umbrella term used to describe any number of ailments that cause inflammation of the stomach lining, painful flatulence and abdominal pain in dogs. Gastritis can be caused by a virus, bacteria, systemic infection, allergy or dietary indiscretion and is generally highly treatable; however, don't try to treat it on your own. Veterinary attention is always necessary to prevent dehydration and further infection.

  1. Vomiting

    • According to Pet Place, vomiting is the most common symptom of canine gastritis. Your dog will typically vomit foamy yellow bile, perhaps with flecks of blood. If her stomach is bleeding, her vomit may look like coffee grounds.

    Loss of Appetite

    • If your dog has gastritis, one of the first visible signs will be a loss of appetite. Because your dog's stomach lining is inflamed and may be filled with painful gas, the last thing he will want is food.

    Lethargy

    • Due to the irritation and pain associated with gastritis, your dog will probably become lethargic. She may appear frightened for no reason or just curl up in her bed and refuse to move.

    Diarrhea

    • According to Pet Education, if gastritis is allowed to progress untreated, especially if the cause is a bacterial or viral infection, your dog may develop diarrhea. If your dog's stomach or intestines are bleeding, his stool may appear black in color.

    Fever

    • Gastritis will often cause your dog's temperature to elevate above her normal 101.5 degrees F. Only your veterinarian will be able to determine if your dog has a fever, which is why veterinary attention is so important when your dog is sick.
