Grain Allergies in Pets: Fact or Fiction?
When it comes to choosing the right food for your pet, there's significant debate about grains. While some owners swear by grain-free diets, others question whether grains are truly harmful. At DR. JOE’S Premium Pet Food, we believe in science-based nutrition, so let's examine the facts about grain allergies and sensitivities in dogs and cats.
Are Grain Allergies in Pets Common?
The short answer? No—true grain allergies are rare.
A food allergy occurs when a pet's immune system mistakenly identifies a protein as harmful and triggers an allergic response, typically causing itchy skin, ear infections, or digestive upset. Research shows that most food allergies in dogs and cats are caused by animal proteins, not grains.
A 2017 study in BMC Veterinary Research found that the most common allergens in dogs were:
Beef (34%)
Dairy (17%)
Chicken (15%)
Wheat (13%)
In cats, a 2016 study in Veterinary Dermatology revealed that the most common food allergies were to beef, fish, and chicken—not grains. While some dogs and cats do react to wheat, these reactions are far less frequent than those to certain meats.
Grain Intolerances vs. True Allergies
Though grain allergies are uncommon, some pets may have grain intolerances —meaning they have difficulty digesting grains properly. Unlike allergies, intolerances don't trigger the immune system but can cause:
Loose stools or diarrhoea
Excess gas and bloating
Chronic itching without a clear cause
Certain breeds, such as Irish Setters, have been specifically studied for gluten sensitivity, which can cause long-term digestive issues.
Why Choose a Grain-Free Diet?
Pet owners often choose grain-free diets not just because of allergies, but for their observed benefits, including:
Better digestion - Some dogs and cats experience fewer digestive issues on grain-free food.
Healthier skin & coat - High-protein, grain-free diets may improve skin health.
Lower inflammation - Some sensitive pets show reduced inflammation without grains like wheat.
More protein, fewer fillers - Grain-free diets typically emphasise high quality protein sources.
This is why DR. JOE’S Premium Pet Food is grain-free, using only carefully selected, high-quality ingredients that support optimal digestion and long-term health.
