Chronic Gastritis in Dogs: Causes, Symptoms & Care
Understanding Chronic Gastritis in Dogs
Chronic gastritis is a prolonged inflammation of the stomach lining in dogs, often leading to repeated bouts of vomiting, loss of appetite, and abdominal discomfort. Identifying and treating this condition requires careful evaluation by a licensed veterinarian in the US to address the underlying causes effectively.
Common Causes of Chronic Gastritis in Dogs
- Food Allergies and Intolerances: Continuous exposure to certain food components can trigger an immune response, causing stomach lining irritation in dogs.
- Infections: Persistent infections, including Helicobacter species bacteria, may cause ongoing inflammation.
- Immune-Mediated Disorders: Conditions like inflammatory bowel disease (IBD) cause immune dysfunction that can inflame the stomach.
- Systemic Health Issues: Diseases such as kidney failure, liver problems, or pancreatitis can result in secondary gastritis due to metabolic disturbances.
- Gastric Cancer: Less frequently, cancers such as lymphoma or carcinoma of the stomach can cause chronic irritation and inflammation.
Key Symptoms to Watch For
Signs that might suggest chronic gastritis in your dog include:
- Frequent vomiting, sometimes containing bile or traces of blood indicating damage to the stomach lining
- Decreased appetite with subsequent weight loss
- Signs of abdominal discomfort, like restlessness or pacing
- Lethargy or weakness
- Diarrhea or tarry, black stools suggesting gastrointestinal bleeding
- Dehydration and dull coat condition
Diagnosis
A thorough examination by a US-licensed veterinarian includes a physical check, blood work, stool analysis, and diagnostic imaging such as ultrasound or X-rays of the abdomen. In certain cases, endoscopic gastric biopsies are performed for a definitive diagnosis.
Treatment and Care
Therapy will depend on the root cause of the gastritis. Common treatments might involve:
- Changing to a bland, hypoallergenic, or veterinary prescription diet designed to soothe the stomach lining
- Medications like acid reducers (famotidine or omeprazole) and anti-nausea drugs prescribed by your vet
- Treating concurrent infections or systemic illnesses as necessary
Important Reminder: Never give your dog Calpol (paracetamol/acetaminophen) or any human pain relievers, as these can be toxic and cause serious harm. Always seek veterinary guidance in the US before administering any medication.
Breeds Prone to Chronic Gastritis
Certain breeds have a genetic predisposition to immune-mediated gastric disorders. In the US, breeds such as the Lhasa Apso puppies, Shih Tzu puppies, and Miniature Poodle puppies—all small breeds—are more frequently affected. Larger breeds, including the Basenji puppies, may also be at increased risk. Awareness of breed susceptibility helps in early detection and preventive care.
When to Contact a Veterinarian
If your dog persistently vomits for more than two weeks or shows severe signs like pale gums, collapse, or extreme lethargy, immediately consult your veterinarian for urgent evaluation. Early diagnosis and tailored treatment lead to the best outcome.
Supporting Your Dog’s Digestive Health at Home
After diagnosis and initial treatment, supporting your dog includes feeding smaller, more frequent meals to ease digestion, providing a calm environment to reduce stress, following the vet’s dietary recommendations strictly, and scheduling regular veterinary check-ups. These steps promote healing and help prevent future episodes.
For additional guidance and reputable dog breed information, resources such as the American Kennel Club and VCA Animal Hospitals websites offer comprehensive support for pet owners in the United States.
