What is a Food Intolerance in Dogs?
Food intolerance in dogs occurs when a dog’s digestive system cannot properly break down or process certain foods, leading to discomfort and gastrointestinal issues. Unlike a food allergy, which involves the immune system, food intolerance typically does not provoke an immune response. Instead, it relates to the body’s inability to metabolise certain components, such as proteins, fats, or carbohydrates. (1)
For example, lactose intolerance, a common condition in dogs, arises from the lack of lactase, the enzyme responsible for breaking down lactose in dairy products. When dogs with lactose intolerance consume dairy, they experience symptoms like diarrhoea and gas because their digestive system cannot efficiently process the lactose. (2)
Food intolerances are not life-threatening but can cause ongoing discomfort and health issues if not properly addressed. They may develop gradually over time and can worsen if the dog continues to be exposed to the problem ingredient.
What are the Differences Between Food Intolerance and Food Allergies?
Food intolerance and food allergies are often confused due to overlapping symptoms, but they involve very different physiological mechanisms.
- Food Allergies: These involve an abnormal immune response to a particular food. When a dog consumes a food they are allergic to, their immune system mistakes it for a harmful invader and triggers an allergic reaction. Common signs of food allergies include itchy skin, rashes, ear infections, and in severe cases, anaphylaxis. (4)
- Food Intolerance: This condition occurs when the digestive system cannot properly process or metabolise a specific food component. It does not involve the immune system and typically results in gastrointestinal issues like bloating, gas, diarrhoea, or vomiting.
The key distinction lies in the involvement of the immune system—food allergies cause an immune reaction, while food intolerances are more of a digestive issue.
What are the Symptoms of Food Intolerance in Dogs?
Food intolerance can manifest in various ways, most commonly through digestive symptoms. The following are signs that your dog may be suffering from food intolerance:
- Diarrhoea: One of the most prevalent symptoms, caused by the body’s inability to process certain foods properly.
- Vomiting: Food that isn’t properly digested can lead to vomiting shortly after eating.
- Excessive flatulence: Gas can result from improper digestion, particularly when the dog’s system struggles with carbohydrates or proteins.
- Abdominal pain: Dogs may show signs of discomfort, such as whining, stretching, or guarding their abdomen.
- Weight loss: Chronic diarrhoea and poor digestion can lead to weight loss over time, as the dog is unable to absorb nutrients properly.
- Lethargy: A lack of energy may result from malnutrition or ongoing discomfort.
- Itchy skin or hair loss: Although more common with food allergies, some dogs with food intolerances may develop skin conditions as a secondary issue due to digestive inflammation or nutritional deficiencies.
What is a Food Intolerance Test for Dogs?
Diagnosing food intolerance in dogs often requires a systematic approach to rule out other potential causes and pinpoint the specific food or ingredient responsible for the symptoms. The two most common methods are:
- Elimination Diet: This is the gold standard for identifying food intolerances. The dog is placed on a bland, hypoallergenic diet with limited ingredients for 8 to 12 weeks. If symptoms improve, ingredients are reintroduced one by one to determine which food is causing the intolerance. It is essential to follow this process under veterinary guidance to ensure the diet remains nutritionally balanced.
- Veterinary Tests: Some vets offer blood tests or faecal analysis to identify food intolerances, but these are generally less reliable than elimination diets. However, they can provide additional insight into potential intolerances or help rule out other conditions.
What are the Treatment Protocols for Dogs with Food Intolerances?
Once a food intolerance is identified, treatment focuses on managing the condition through dietary adjustments. Key treatment protocols include:
- Eliminate the Trigger: Remove the offending food or ingredient from your dog’s diet permanently. This may involve avoiding certain proteins, grains, or additives known to cause symptoms.
- Limited Ingredient Diet (LID): Many dogs benefit from a limited ingredient diet, which contains fewer ingredients and is designed to reduce the likelihood of food intolerances. LID diets often use novel protein sources like venison or duck or plant-based protein sources and carbohydrate sources like sweet potatoes.
- Hydrolysed Protein Diet: In this specialised diet, proteins are broken down into smaller molecules that are less likely to trigger an adverse reaction. This diet is usually prescribed by a vet and is especially useful for dogs with severe intolerance to animal proteins.
- Supplements: Probiotics, digestive enzymes, and omega-3 fatty acids can be added to the dog’s diet to support gut health, improve digestion, and reduce inflammation.
- Gradual Introduction of New Foods: If new foods are being introduced, it’s important to do so slowly and monitor your dog for any signs of intolerance.
What Foods are Most Likely to Cause Intolerance?
Certain foods are more likely to trigger food intolerance in dogs. Some of the most common culprits include: (5)
- Dairy: Many dogs are lactose intolerant and have difficulty digesting milk, cheese, and other dairy products.
- Wheat and Gluten: Grains such as wheat and barley can cause digestive issues in dogs, particularly those sensitive to gluten.
- Soy: Some dogs are intolerant to soy, which is often used as a protein source in low-quality dog foods.
- Corn: Corn is another common ingredient in dog food that can be difficult for some dogs to digest.
- Animal Proteins (Beef, Chicken, Lamb): Dogs can develop intolerances to specific proteins, particularly those found in common meats such as beef, chicken, and lamb.
- Artificial Additives: Preservatives, flavour enhancers, and artificial dyes can also trigger food intolerance in sensitive dogs.
Best Foods, Nutrients, and Supplements for Food Intolerances
When managing a dog with food intolerance, choosing the right foods and supplements can make a significant difference in their health. Consider the following:
- Novel Proteins: Proteins like duck, venison, rabbit, or plant-based proteins like peas, chickpeas, barley, fava beans, potato and lentils can provide essential amino acids while reducing the risk of intolerance.
- Digestible Carbohydrates: Carbohydrates such as sweet potatoes, quinoa, brown rice and pumpkin are easy on the digestive system and less likely to cause gastrointestinal upset.
- Omega-3 Fatty Acids: Found in flaxseed, algae oil, and fish oil, omega-3s are known for their anti-inflammatory properties and can support skin and coat health as well as digestive health.
- Probiotics: Probiotics like Bacillus velezensis, Lactobacillus acidophilus and Bifidobacterium animalis promote gut health and help balance the microbiome, aiding in digestion and potentially reducing symptoms of food intolerance.
- Digestive Enzymes: Enzyme supplements can help break down proteins, fats, and carbohydrates, improving digestion and nutrient absorption.
