It’s heartbreaking to see your dog feeling unwell, especially when they can’t tell you what’s wrong. Gastric ulcers and gastritis are common issues in dogs that can cause discomfort, pain, and even serious health complications if left untreated. As a pet parent, knowing the signs and how to help your furry friend can make all the difference.

⚠️ What to Watch For

Recognizing the symptoms of gastric ulcers and gastritis in dogs is key to catching the condition early. While symptoms can vary depending on the severity, here are the most common signs to look out for:

  • Vomiting, sometimes with blood
  • Loss of appetite
  • Weight loss
  • Abdominal pain or bloating
  • Dark, tarry stools (a sign of digested blood)
  • Lethargy or weakness
  • Excessive drooling

If you notice any of these symptoms, especially vomiting or blood in stools, it's important to take action quickly. Gastric issues can progress rapidly and may lead to complications like dehydration or anemia.

🔍 Possible Causes

Gastric ulcers and gastritis can be triggered by several factors, ranging from dietary issues to underlying medical conditions. Here’s a breakdown of potential causes:

  • Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin can irritate your dog’s stomach lining.
  • Dietary indiscretion: Eating spoiled food, garbage, or toxic substances can lead to gastritis.
  • Stress: Chronic stress or anxiety can increase stomach acid, leading to ulcers.
  • Bacterial infections: Helicobacter pylori and other bacteria can inflame the stomach lining.
  • Underlying health conditions: Liver or kidney disease, cancer, or hormonal imbalances may contribute to gastric ulcers.
  • Foreign objects: Swallowing non-food items like toys or bones can irritate the stomach and cause gastritis.

Understanding the root cause is crucial for effective treatment, so your vet may recommend diagnostic tests like bloodwork, x-rays, or ultrasounds to investigate further.

✅ What You Can Do at Home

While professional veterinary care is essential for treating gastric ulcers and gastritis, there are steps you can take at home to support your dog’s recovery:

  • Feed a bland diet of boiled chicken and rice for a few days to soothe the stomach.
  • Ensure your dog has access to fresh, clean water to prevent dehydration.
  • Remove any potential irritants from your dog’s environment, such as toxic foods or chemicals.
  • Avoid giving your dog over-the-counter medications without consulting your vet, as some can worsen the condition.

These steps can help manage mild cases of gastritis, but they are not a substitute for veterinary care if symptoms persist or worsen.

💡 When to Call a Vet

If your dog’s symptoms are severe, persistent, or worsening, it’s time to contact your veterinarian. Here are some red flags that require immediate attention:

  • Vomiting blood or passing black, tarry stools
  • Severe abdominal pain or bloating
  • Refusal to eat for more than 24 hours
  • Signs of dehydration, such as dry gums or sunken eyes
  • Sudden weight loss or extreme lethargy

Your vet may prescribe medications to reduce stomach acid, protect the stomach lining, or treat any underlying infections. In severe cases, hospitalization for IV fluids and monitoring may be necessary.
