🐶 Allergies and Diet in Dogs: What You Need to Know
Food plays a major role in your dog's overall health, and for some dogs, the wrong ingredients can lead to uncomfortable—and sometimes serious—allergic reactions. Understanding how diet affects allergies in dogs can help you make better food choices and keep your pup feeling their best.
🐾 What Are Dog Allergies?
Allergies in dogs happen when their immune system overreacts to a substance (called an allergen), which could be something in the environment or something they eat.
The three most common types of dog allergies are:
- Environmental (atopic) allergies – e.g., pollen, mold, dust mites.
- Flea allergy dermatitis – an allergic reaction to flea saliva.
- Food allergies – a reaction to proteins or ingredients in the dog’s food.

🍗 Food Allergies vs. Food Sensitivities
- Food allergies involve an immune response and typically cause skin issues like itching or chronic ear infections.
- Food sensitivities (also called intolerances) don’t involve the immune system and usually result in digestive issues like gas, bloating, or diarrhea.

🐕🦺 Common Signs of Food Allergies in Dogs
- Constant itching or licking (especially paws)
- Ear infections or head shaking
- Red or inflamed skin
- Vomiting or diarrhea
- Chronic gas or bloating
If your dog shows any of these symptoms, a dietary cause should be considered—especially if symptoms persist despite other treatments.

🥩 The Elimination Diet: Finding the Culprit
If you suspect a food allergy, your vet may recommend an elimination diet, which involves feeding your dog a novel protein (like duck, rabbit, or kangaroo) and carbohydrate (like sweet potato) that they’ve never eaten before. After 8–12 weeks, ingredients are slowly reintroduced to identify the allergen.

✅ Best Diet Practices for Dogs with Allergies
- Choose limited ingredient diets (LID) with one protein and one carb source.
- Look for novel proteins like venison, duck, or salmon.
- Avoid artificial preservatives, colorants, and grains if they cause reactions.
- Consider raw or home-prepared diets (under guidance) for full control over ingredients.

🐶 Raw Diets and Allergies: A Natural Solution?
Some owners report improved allergy symptoms when switching to raw diets—often because they're eliminating processed ingredients and common allergens. While more research is needed, anecdotal evidence and holistic vets often support raw feeding for allergy-prone dogs.

Final Thoughts
Managing your dog’s allergies starts with what goes in their bowl. By identifying allergens and providing a clean, simple diet, you can drastically reduce allergy symptoms and improve your dog’s quality of life. If you're unsure where to start, speak to your vet about doing a food trial or switching to a hypoallergenic or raw diet.
