A food allergy occurs when proteins in otherwise nutritious sources of food are mistaken by the dog’s immune system as ‘invaders’. To combat these invaders, the immune system engages in a response to protect itself.

These responses often manifest themselves as itchy skin, ear infections, diarrhoea, and vomiting in the worst cases. The combination of both intestinal complications and skin irritation can be very uncomfortable for dogs, as any pet owners know.

Just like their human counterparts, dogs can suffer from allergies brought on by different types of foods.

And these food allergens can be far more common than we would expect.

Grains, protein meats, and vegetables – common ingredients found both in commercial dog food and in home recipes alikeĀ  – can bring warning signs for our sensitive friends.

There are all kinds of common food allergens many dog owners might be unfamiliar with. This guide from Dogs Naturally Magazine has everything to help get you started.
