Why Diet Matters for Dogs with Allergies
Common Allergens in Commercial Dog Food
Dogs often react to proteins like beef, chicken, and dairy. Grains—corn, wheat, and soy—can also trigger sensitivity. Understanding these triggers is key to picking a safe food.
Symptoms That Warrant a Food Change
Red, itchy skin, ear infections, and digestive upset are classic signs. If your vet suspects an allergy, a diet trial can confirm the culprit.
How Food Impacts Immune Function
High‑quality proteins and essential fatty acids help strengthen a dog’s immune response, while anti‑inflammatory ingredients reduce chronic inflammation.
