Pet Food Allergen
Oats Allergy in Dogs and Cats
Oats are primarily used in pet food for their soluble fibre (beta-glucan) rather than their protein. They contain a naturally-occurring gluten protein (avenin) that cross-reacts with wheat gluten in some sensitised dogs — so oats are not always a safe substitute for wheat-reactive pets.
Prevalence
Genuine oat allergy is uncommon in dogs; cross-reactivity from wheat gluten sensitivity accounts for most reported reactions.

Cross-reactivity
A pet allergic to oats may also react to: wheat (via gluten cross-reactivity). Cross-reactivity is not guaranteed, but it is common enough that it should inform an elimination diet.
