Anallergenic Dry Dog Food

Overview
Royal Canin Anallergenic is a veterinary-formulated dry dog food designed for dogs with severe food allergies and dietary intolerances. This prescription diet uses extensively hydrolysed feather protein broken down into small oligopeptides and pure amino acids, significantly reducing the risk of triggering an adverse food reaction. It is one of the most restrictive elimination diets available in veterinary nutrition.
The formula relies on maize starch as a highly digestible and hypoallergenic energy base. Copra oil and soya oil supply essential fatty acids including linoleic acid to support skin barrier function and a healthy coat, which is particularly important for dogs experiencing dermatological symptoms linked to food sensitivities.
Chicory pulp and fructo-oligosaccharides act as prebiotic fibres to support digestive health and beneficial gut bacteria. Fish oil provides omega-3 fatty acids to help manage skin inflammation often associated with canine atopic dermatitis and inflammatory bowel disease. This is a complete and balanced formula suitable for long-term feeding under veterinary supervision.
