Food Allergies in Dogs in 2025: Vet‑Reviewed Guide to Symptoms, Diagnosis & Management 🍽️🐶

By Dr. Duncan Houston BVSc

🔍 What Are Food Allergies?

Food allergies (adverse food reactions) happen when a dog’s immune system overreacts to a protein or other ingredient—most commonly beef, chicken, dairy, wheat, soy, or eggs.

⚠️ Common Signs to Watch For

  • Itchy, red skin—especially paws, ears, face.
  • Frequent ear or skin infections and hair loss.
  • Licking or chewing paws, greasy coat, and dandruff.
  • Digestive issues—vomiting, diarrhea, gas, soft stools.

🧬 Who’s at Risk?

Any dog can develop a food allergy at any age, though breeds like Labradors, Cocker Spaniels, and Westies are predisposed.

🩺 Diagnosis via Elimination Diet

The gold standard is an 8–12 week strict elimination trial using a novel (unfamiliar protein) or a hydrolyzed prescription diet. No treats or other foods allowed.

✅ Treatment & Diet Management

  • Novel or hydrolyzed prescription diets—continue long-term if effective.
  • Supplements: omega‑3 fatty acids, vitamins A/E, zinc support skin and gut health.
  • Manage secondary infections with vet-prescribed antibiotics/antifungals.
  • Concurrent allergy medications (e.g., Apoquel, Cytopoint) may help while diet changes take effect.

📅 Monitoring & Follow‑Up

  • Expect gradual improvement—itch may ease in 4 weeks, full resolution may take up to 12 weeks.
  • Reintroduce ingredients one at a time post-trial to confirm allergens under vet guidance.
  • Ongoing vet checkups for coat, skin, ears, and GI health.

🔚 Final Thoughts

Food allergies can significantly affect skin and digestive health, but with a methodical elimination trial, prescription diet, and supportive care, most dogs can remain comfortable, itch-free, and healthy 🍃🐾.
