What is Inflammation in Dogs?

Inflammation is the body’s natural response to injury, infection, or harmful stimuli. In dogs, it serves as a protective mechanism to isolate and repair damage. However, when inflammation becomes chronic, it can contribute to various health issues, impacting the dog’s quality of life.

Acute vs. Chronic Inflammation

• Acute Inflammation: This type of inflammation occurs as a short-term response to injury or infection. It typically manifests with redness, swelling, heat, pain, and sometimes loss of function in the affected area. For example, a dog with a cut or wound may show localised inflammation as the body works to heal itself.
• Chronic Inflammation: Unlike acute inflammation, chronic inflammation is long-lasting and can occur even in the absence of an obvious injury or infection. It is often linked to diseases such as arthritis, inflammatory bowel disease (IBD), and certain skin conditions. Chronic inflammation can gradually damage tissues and organs, potentially leading to severe health issues.

What Causes Inflammation in Dogs?

Common Triggers of Inflammation

1. Infections: Bacterial, viral, or fungal infections are common causes of inflammation. For example, a bacterial infection in the skin can lead to swelling and redness.
2. Allergens: Environmental allergens such as pollen, dust mites, and mould can cause systemic or localised inflammation, often resulting in conditions like atopic dermatitis. Dietary allergens, including specific proteins or grains, may lead to gastrointestinal issues or skin-related issues.
3. Injuries: Physical trauma, such as cuts, sprains, or fractures, triggers an inflammatory response as the body works to repair damaged tissues.
4. Diet: Certain foods can directly or indirectly contribute to inflammation. Poor-quality diets high in processed ingredients, artificial additives, and unhealthy fats can exacerbate inflammatory responses, particularly in dogs predisposed to sensitivities or chronic conditions.

What Foods Can Cause Inflammation?

Processed Foods

Highly processed dog foods often include preservatives, artificial colours, and flavours that can disrupt normal metabolic functions and trigger inflammatory pathways. These foods are usually low in essential nutrients and high in fillers that provide little to no health benefits.

Foods High in Saturated Fats

Saturated fats, found in fatty cuts of meat, butter, and some low-quality dog treats, can increase levels of LDL cholesterol (the “bad” cholesterol) in dogs. This, in turn, promotes systemic inflammation by impairing normal cellular functions and contributing to oxidative stress.

Foods High in Refined Carbohydrates

Refined carbohydrates, such as white rice, white bread, and sugary treats, are rapidly digested, leading to spikes in blood sugar levels. This glycaemic surge can trigger the release of pro-inflammatory cytokines and exacerbate chronic inflammatory conditions, including arthritis and diabetes.

Artificial Additives and Preservatives

Ingredients such as BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), and ethoxyquin are commonly used in pet foods to prolong shelf life. These compounds have been linked to inflammation and oxidative stress, potentially leading to long-term health issues.

Allergenic Foods

Common dietary allergens include:

• Wheat: Often used as a filler, wheat can cause gastrointestinal or skin inflammation in sensitive dogs.
• Corn: Another of the grains that can be the cause of a food related enteropathy or skin inflammation in dogs
• Soy: Soy proteins can provoke allergic reactions in dogs predisposed to food sensitivities.
• Dairy: Lactose intolerance or sensitivity to dairy proteins often leads to gastrointestinal discomfort and inflammation.

Certain Animal Proteins

Proteins like beef, chicken, fish and pork can trigger inflammatory responses in some dogs, particularly if the animal protein is sourced from poorly managed livestock raised with antibiotics or hormones. These additives can disrupt the dog’s immune system, increasing susceptibility to inflammation.

Why Are These Foods Inflammatory?

Mechanisms of Inflammatory Foods

1. Oxidative Stress: Foods high in unhealthy fats and sugars increase the production of free radicals, which cause oxidative damage to cells and tissues, perpetuating inflammation.
2. Imbalanced Gut Microbiota: Refined carbohydrates and artificial additives can disrupt the gut’s microbial balance, leading to dysbiosis. An imbalanced gut microbiota often triggers systemic inflammation.
3. Allergic Reactions: When a dog’s immune system identifies certain proteins or compounds as harmful, it releases histamines and inflammatory cytokines to neutralise the perceived threat, causing localised or systemic inflammation.
4. Endotoxins: Animal proteins sourced from low-quality suppliers may carry endotoxins—toxic substances released by bacteria—that activate the immune system, leading to inflammation.

What Parts of a Dog’s Body Are Most Likely to Be Inflamed by Food?

Gastrointestinal Tract

• Symptoms: Chronic diarrhoea, vomiting, bloating, and gas.
• Culprits: Foods high in fat, artificial additives, and common allergens such as dairy and wheat. The GI tract is particularly sensitive to food-related inflammation due to its constant exposure to dietary antigens.

Skin and Coat

• Symptoms: Itching, redness, rashes, hot spots, and hair loss.
• Culprits: Allergens like soy, chicken, and grains. Food-related inflammation often manifests as atopic dermatitis, which can significantly affect a dog’s comfort and appearance.

Joints

• Symptoms: Stiffness, swelling, and reduced mobility.
• Culprits: Pro-inflammatory foods like fatty meats and sugary treats. Chronic inflammation in joints can exacerbate conditions such as arthritis, particularly in older dogs.

Organs (e.g., Liver, Kidneys, Pancreas)

• Symptoms: Fatigue, jaundice, abdominal pain, and changes in appetite.
• Culprits: Diets high in saturated fats and artificial preservatives can overburden these organs, leading to inflammation and impaired function and liver disease, kidney disease or pancreatitis.

What Are the Best Options for Preventing or Reducing Inflammation in Dogs?

Anti-Inflammatory Foods

1. Omega-3 Fatty Acids: Found in flaxseed, algae oil, and fish oil, omega-3s reduce inflammatory mediators in the body, benefiting joints, skin, and overall health.
2. Fruits and Vegetables: Rich in antioxidants, options like blueberries, cranberries, spinach, and sweet potatoes help neutralise free radicals and reduce oxidative stress.
3. Whole Grains: Quinoa and oats provide anti-inflammatory benefits through their fibre and nutrient content, supporting gut health and reducing systemic inflammation.
4. Herbs and Spices: Natural anti-inflammatories like turmeric (curcumin), ginger, and chamomile can be safely incorporated into your dog’s diet under veterinary guidance.

Nutritional Strategies

• Eliminate Trigger Foods: Remove processed foods, artificial additives, and common allergens from your dog’s diet.
• Enhance Gut Health: Include prebiotics (e.g., chicory root) and probiotics to maintain a healthy gut microbiota, which plays a crucial role in modulating inflammation.
• Balanced Diet: Ensure your dog’s diet is nutritionally complete and tailored to their specific needs, considering age, breed, and health conditions.

Lifestyle Adjustments

• Exercise: Regular physical activity helps reduce systemic inflammation and supports joint health.
• Stress Reduction: Minimise environmental stressors through mental stimulation, predictable routines, and calming environments.
• Veterinary Support: Work with your vet to monitor inflammatory markers and adjust your dog’s diet and care plan as needed.

Conclusion

Diet plays a pivotal role in managing inflammation in dogs. By understanding which foods to avoid and incorporating anti-inflammatory options, pet owners can significantly improve their dog’s overall health and well-being. Always consult a veterinarian for personalized dietary recommendations tailored to your dog’s unique needs.
