Are Food Allergies Common in Dogs?
Yes — and widely underdiagnosed. Food allergies account for 10–15% of all allergy cases we see. Symptoms overlap with environmental allergies, making diagnosis a process of careful elimination.
🔍 Key clue: Environmental allergies are seasonal. Food allergies happen year-round. If your dog itches in winter — think food first.
Signs of a Food Allergy
- Itching — especially paws, ears, groin, and belly
- Recurrent ear infections — diet is often the cause
- Chronic skin issues — red, flaky, irritated skin year-round
- Digestive issues — loose stools, vomiting, excessive gas
Most Common Allergens
- Chicken — most common in Indian dogs
- Beef, Dairy, Wheat, Eggs, Soy
Diagnosis
The gold standard is an elimination diet trial — 8–12 weeks feeding a novel protein your dog has never eaten. Blood tests and skin prick tests for food allergies in dogs are unreliable.
⚠️ Do not rely on quick test kits sold online. Only the elimination diet trial gives a definitive answer.
