    Symptoms of Stomach Ulcers in Dogs

    Stomach ulcers in dogs are not that uncommon and can be caused by a variety of factors. If your dog has been affected with stomach ulcers, the most common symptom is vomiting. Other symptoms can include:

    • Loss of appetite
    • Weight loss
    • Dull coat
    • Diarrhea

    It is important to identify the symptoms of stomach ulcers in dogs as soon as possible, so that you can start the best diet and treatment plan for your pet.


    Vomiting is one of the most common symptoms of stomach ulcers in dogs. It’s also one of the most worrisome, as it likely involves regurgitated bile or blood. In cases where a dog has had multiple episodes of vomiting, they may produce small amounts of liquid (known as bilious vomiting) that smells like bile. However, sometimes dogs will also vomit undigested food particles or even have traces of blood in their vomit.

    In addition to vomiting, dogs with stomach ulcers can experience decreased appetite, abdominal pain and discomfort, weight loss and dehydration. Diagnosis is typically made with abdomen x-rays, ultrasound or an endoscopy to examine the stomach directly for signs of ulceration.

    The best diet for a dog with stomach ulcers is a low fat and highly digestible diet supplemented with probiotics and an antacid medication to help reduce inflammation and promote healing.


    Diarrhea is a common symptom of stomach ulcers in dogs. It can range from loose, watery stool to frequent trips outside with normal-looking stools. Diarrhea can be an indicator that something is wrong and should be addressed with a vet visit.

    In the case of stomach ulcers, the digestive system becomes inflamed which can cause diarrhea to occur. The dog may also experience vomiting, dehydration, loss of appetite or weight loss as a result of their stomach ulcer.

    As always, it is important to have your pet seen by a vet to confirm diagnosis and rule out other GI issues that may be causing diarrhea; however, if your pet has been diagnosed with stomach ulcers you should focus on providing them with nutrition that will help support their GI health such as a low-fat, easy-to-digest diet and avoiding foods high in fat or acid. Additionally, probiotics may be beneficial in helping support the digestive system while antibiotics will help treat the underlying infection.

    Loss of Appetite

    Loss of appetite resulting from stomach ulcers in dogs is one of the most common symptoms. Dogs affected by stomach ulcers may not eat much or at all and they may be unresponsive to food, even if they are normally food-motivated. If your dog has lost their appetite, it’s important to have them examined by a veterinarian as soon as possible.

    Other common symptoms of stomach ulcers in dogs include:

    • Vomiting
    • Diarrhea
    • Bad breath
    • Bloating
    • Weight loss

    Stomach ulcers can be treated with medications and dietary changes; however, it is important to diagnose the condition quickly so that it can be managed effectively. An appropriate diet for dogs with stomach ulcers should also focus on providing your pet with nutrient-rich foods that are easy to digest and contain fiber for better digestion.

    Causes of Stomach Ulcers in Dogs

    Stomach ulcers in dogs are painful and can be caused by a variety of factors, such as medications, infections, and stress. Diet can also be a cause of stomach ulcers in dogs, as some foods can be acidic and may irritate the stomach lining. Thus, it is important to be mindful of what diet is best for a dog who suffers from stomach ulcers.

    Dietary considerations for dogs with stomach ulcers include:

    • Avoiding foods that are high in fat and acidity
    • Providing easily digestible, nutrient-rich food
    • Introducing probiotics to help restore the natural balance of bacteria in the gut
    • Feeding smaller, more frequent meals

    Bacterial Infection

    Stomach ulcers in dogs can be caused by a variety of factors, but the most common cause is a bacterial infection. This type of infection occurs when bacteria from the dog’s environment inhabit the stomach and cause inflammation. This type of infection is known as Helicobacter pylori, a species of bacteria that can lead to gastritis and stomach ulcers. Other than bacteria, parasites can also cause stomach ulcers in dogs. In these cases, it is important to consult a veterinarian to identify the exact disease causing organism.

    The best diet for dogs with stomach ulcers includes high-quality proteins, complex carbohydrates, and beneficial fats. Foods that are known to aggravate an inflamed or irritated digestive system should be avoided completely or fed in very small amounts. The main nutrients needed by all dogs include:

    • Protein sources such as lean meats or fish;
    • Complex carbohydrates like brown rice or oat bran; and
    • Beneficial fats like olive oil, flaxseed oil, fish oil, and coconut oil.

    Additionally, it is recommended that dogs with stomach ulcers receive probiotic supplements to help strengthen their overall health.


    Stress is a major factor in the development of stomach ulcers in dogs. Stress can be both physical and psychological and can be caused by any number of sources. Examples of physical stressors include extreme temperatures, changes in activity levels, or long-distance travel. Psychological stressors are those that are related to social interactions or changes in environment or routine, such as separation from a loved one. Additionally, dogs can also suffer from chronic stress due to poor nutrition, disease, or lack of exercise.

    To help reduce your dog’s risk for developing stomach ulcers due to stress, it is important that your dog is provided with enough exercise, mental stimulation, and social interaction with other dogs and people. Additionally, providing your dog with a balanced diet full of nutrients will help to ensure overall health and reduce the chances of developing an ulcer.

    Eating multiple small meals throughout the day instead of one large meal will also help reduce the risk for developing an ulcer due to increased digestive acid levels created by consuming large amounts of food at once:

    • Eat multiple small meals throughout the day.
    • Provide a balanced diet full of nutrients.
    • Ensure enough exercise, mental stimulation, and social interaction.


    Stomach ulcers in dogs can be caused by a variety of medications, including corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), and antibiotics. These medications can destroy the protective mucus layer that lines the stomach, which allows harsh digestive acids to come into contact with the sensitive stomach lining and cause ulceration.

    Therefore, if your pet is taking any of these medications, it’s important to monitor them for signs of gastrointestinal distress such as vomiting or diarrhea. If any signs are present, speak to your veterinarian about adjusting the dosage or switching to an alternative medication.

    Proper diet is also important for dogs who suffer from stomach ulcers and other gastrointestinal issues—low-fat foods like boiled chicken, turkey, and fish are usually tolerated well by affected animals.

    Dietary Recommendations for Dogs with Stomach Ulcers

    Diet can be a crucial part of treating and managing stomach ulcers in dogs. It is important to ensure that your pet is receiving the necessary nutrients for their health, but also to avoid foods that may worsen their ulcers.

    Let us go over some important dietary recommendations for dogs with stomach ulcers:

    Low-fat Diet

    Low-fat diets are often recommended for dogs suffering from stomach ulcers as fat triggers production of stomach acid. Therefore, a diet containing low amounts of fat is important to keep stomach acid levels low.

    It is also recommended that the types of fat used in the diet are rich in omega-3 fatty acids, such as tuna oil and salmon oil, which can help reduce inflammation and promote healing. Omega-6 fatty acids should be avoided when feeding a dog with stomach ulcers, as these can promote inflammation and hinder healing.

    It’s also important to feed your dog with stomach ulcers small meals more often throughout the day as larger meals may increase levels of acidity in the gut.

    A low-fat diet should include:

    • Boiled or pureed chicken or turkey (without skin)
    • Cooked fish (without bones)
    • Cooked oats or rice
    • Boiled eggs
    • Vegetables such as carrots and broccoli puree

    Limited Protein Intake

    When it comes to dietary recommendations for dogs with stomach ulcers, limited protein intake is key. Dogs with stomach ulcers should stick to easy-to-digest proteins like chicken, turkey and fish. They should also avoid high fat proteins such as beef and pork. Furthermore, processed foods such as hot dogs or sausage should be avoided if possible. The recommended amount of protein for a dog with stomach ulcers should be around 10-15% of the total caloric intake for an adult dog.

    Additionally, it may be beneficial for dogs with stomach ulcers to eat smaller meals throughout the day rather than larger meals less frequently. This can help prevent overloading the digestive system and can also help keep their energy levels up which is important for proper healing. Additionally, adding probiotics to their diet can improve gut health which may help relieve any associated GI discomfort.

    Fiber-rich Foods

    Fiber-rich foods can be beneficial in treating and preventing stomach ulcers in dogs. Dietary fibres increase production of gastric mucin, which helps to protect the inner layer of the stomach from acid damage. Additionally, dietary fibres also promote healthy digestive motility, which prevents food from lingering in the stomach for too long and can help reduce inflammation associated with stomach ulcers. Furthermore, dietary fibres aid in removing toxins from the body and decreasing absorption of toxins that may cause additional gastric distress.

    Some examples of fiber-rich foods for dogs include:

    • Psyllium husks (ground or sprinkled on food)
    • Pumpkin
    • Chia seeds
    • Quinoa
    • Raw vegetables like broccoli and cauliflower
    • Apples (without skin)
    • Oats

    Supplements to Support Gastric Health

    Diet plays an important role in managing chronic stomach ulcers in dogs. A nutritious diet composed of high-quality proteins, essential fatty acids, and antioxidants can help reduce inflammation and improve digestive health. In addition, certain supplements may be recommended to help support your dog’s gastric health.

    Let’s take a look at some of these supplements:


    Probiotics are beneficial bacteria and yeasts found in many foods that help support the digestive system. Probiotics work by restoring and maintaining the balance of friendly gut bacteria, which is essential for optimal health. Supplementing your dog’s diet with probiotics can help improve overall digestive health, ease stomach upset and improve nutrient absorption. They may also be helpful for dogs suffering from stomach ulcers.

    When selecting a probiotic supplement, look for a product that contains multiple strains of bacteria and yeast, as well as prebiotic ingredients like insoluble fiber from fruits and vegetables. Studies show that certain strains of beneficial bacteria like Lactobacillus acidophilus can help reduce inflammation in the gastrointestinal tract and protect against adverse reactions to food allergens. Additionally, probiotics may help encourage immune system function and reduce or eliminate gas production within the gut walls.

    Digestive Enzymes

    Digestive Enzymes are naturally occurring proteins in the body that help break down food into smaller molecules that can be used by the cells. These enzymes aid in digestion, absorption of nutrients, and waste elimination.

    Digestive enzymes come in different forms and can be found as natural supplements or added to a diet as part of a holistic approach to digestion and health. Natural digestive enzymes include amylase, lipase, protease, cellulase, and lactase. Some digestive enzymes are available in powdered form to be sprinkled on food for easy ingestion.

    Dogs with stomach ulcers may benefit from taking digestive enzyme supplements due to their ability to support a healthy gastric environment and reduce inflammation associated with stomach ulceration. These supplements can also help reduce flatulence caused by poor digestion or slow transit time through the intestines.

    Quality sources of digestive enzymes should be sourced from clean, organic sources along with other nutrients such as probiotics, prebiotics, amino acids, and fatty acids to promote overall gut health.

    Omega-3 Fatty Acids

    Omega-3 fatty acids are a type of polyunsaturated fat that has been shown to be beneficial in people and animals with various gastrointestinal (GI) issues. In dogs, omega-3s have been studied for their ability to reduce inflammation associated with stomach ulcers, limiting the amount of stomach acid produced and speeding up cell repair. In addition, omega-3s can help protect against stress and keep hormones balanced.

    It is important to make sure you are giving your dog a supplement that contains the right ratio of EPA and DHA–two types of omega-3 fatty acids–as each has different benefits. In general, EPA helps reduce inflammation while DHA aids in cell repair. You can find omega-3 fatty acid supplements specifically designed for dogs, as well as those that can be given to both cats and dogs. Excess levels of omega-3s should be avoided as it could lead to vitamin E deficiency or bleeding disorders in some cases.


    In conclusion, the best diet for dogs with stomach ulcers is one that is rich in antioxidants, protein, and omega-3 fatty acids. These nutrients can help reduce inflammation in the digestive system, reduce the production of stomach acid, and increase healing. It is important to speak to your veterinarian before making any diet changes as they will be able to recommend foods that are specific to your pet’s needs and health condition. Additionally, dietary supplements may be recommended.

    The right diet can help provide immediate relief and long-term healing for dogs with stomach ulcers.
