Dog & Cat Food Allergies: Common Triggers, Symptoms & Safer Choices

Food allergies in pets are more common than many Kiwi pet parents realise. If your dog or cat suffers from recurring skin issues, itching, gastrointestinal upset or chronic ear infections, the culprit could be hiding in their food bowl. Understanding which ingredients most commonly cause allergic reactions can help you choose gentler, more nourishing diets for your furry friend. In this guide, we'll explore common dog and cat food allergens, signs to watch for and better options available to support a healthier life for your pet.

What Are The Most Common Allergens For Dogs And Cats?

The most common food allergens in dogs and cats are proteins, grains and dairy. Unlike intolerances, which are digestive in nature, food allergies are immune responses to specific ingredients. The most frequently reported allergens in pets include:

• Beef: A leading allergen for both dogs and cats due to its widespread use in pet foods.
• Dairy: Many animals are lactose intolerant, but in some cases, a true allergy to the proteins in milk products can cause adverse reactions.
• Chicken: A common protein that can lead to allergies, particularly in dogs with sensitive systems.
• Wheat, Corn and Soy: While not inherently harmful, some pets develop sensitivities or allergies to these grains and legumes.
• Eggs: Can trigger allergy symptoms in some pets due to the proteins in egg yolks or whites.

Symptoms Of Food Allergies In Pets

Identifying a food allergy can be tricky, as symptoms often mimic other conditions. If you're noticing recurring issues, it's worth examining your pet’s diet. Common signs of food allergies include:

• Itchy skin, especially around the face, paws, ears and belly
• Chronic ear infections or head shaking
• Frequent gastrointestinal upsets such as vomiting or soft stools
• Excessive licking or chewing on paws or limbs
• Patchy hair loss or recurring hot spots

If your dog or cat is showing these symptoms, talk to your vet about a possible elimination diet to identify potential triggers.

How To Choose The Right Food For Allergy-Prone Pets

Once you suspect a food allergy, adjusting your pet's diet is a critical next step. Hypoallergenic and limited ingredient diets contain fewer components, minimising exposure to common allergens. Look for recipes with:

• Novel proteins like duck, salmon, venison or kangaroo
• Grain-free or alternative grain options such as oats or brown rice
• Single-source proteins for easier tracking of allergens

Supplements And Support For Allergic Pets

In addition to dietary changes, some pets benefit from added support through topical care and supplements. Products containing omega-3 fatty acids, probiotics and skin-supporting nutrients can help reduce inflammation and improve coat health.

Calming allergens such as seasonal pollen or stress-related flare-ups can also play a role. Our calming essentials are ideal for pets with anxiety-related skin issues or digestive stress.
