Royal Canin Anallergenic in Dogs & Cats
Generic: Ultra-hydrolyzed Allergy
Royal Canin Anallergenic is a highly specialized, veterinary-exclusive therapeutic diet formulated with extensively hydrolyzed proteins to minimize the risk of adverse food reactions in dogs and cats.
This medication is intended for dogs and cats.
Overview
Royal Canin Anallergenic is a breakthrough nutritional solution engineered for pets suffering from severe adverse food reactions that have failed to respond to other specialized diets. Unlike standard commercial foods, this diet is produced in a strictly controlled, dedicated manufacturing facility to prevent cross-contamination with other protein sources. It serves as a gold-standard elimination diet, allowing veterinarians to accurately diagnose food allergies or intolerances without the interference of common dietary triggers. When a pet presents with persistent skin irritation or chronic gastrointestinal upset, this diet provides a clean slate for the immune system, effectively silencing the allergic response.
While many diets utilize hydrolyzed protein, Anallergenic takes the process further by utilizing feather-derived protein that is broken down into extremely small peptides. These peptides are so minute that the immune system generally fails to recognize them as potential allergens. This makes it an essential tool for managing atopic dermatitis and chronic inflammatory bowel conditions. By reducing antigenic stimulation, it helps decrease secondary skin infections and alleviates the internal inflammation often managed by Royal Canin Gastrointestinal. Furthermore, it provides the necessary nutrients to maintain skin barrier integrity, which is frequently compromised in allergic pets.
Clinicians often transition patients to this diet when they require a highly digestible, hypoallergenic option that bypasses traditional protein pathways. It is distinct from Royal Canin Renal Support or Royal Canin Hepatic in that its primary objective is immunological exclusion rather than organ support. Because it is so strictly formulated, it should be treated as the sole source of nutrition for the duration of the trial period. Owners are cautioned against offering any treats or table scraps, as even microscopic amounts of an allergen can trigger an adverse reaction, rendering the diagnostic process invalid and potentially causing a flare-up of clinical symptoms.
What It Treats
- Food allergy diagnostics (elimination diet trial)
- Chronic adverse food reactions in dogs and cats
- Atopic dermatitis with concurrent food sensitivities
- Chronic inflammatory bowel disease with suspected food triggers
How It Works
The diet utilizes feather-derived proteins that are processed through a unique hydrolysis method. This technique breaks down the protein molecules into oligopeptides with a low molecular weight, which are too small to be recognized by the immune system's IgE antibodies that typically trigger an allergic reaction. By avoiding these immunological 'red flags,' the body stops attacking itself, allowing inflammation to subside. In addition to the specialized protein source, the diet is formulated with purified corn starch as the primary carbohydrate and highly refined oils to ensure the diet is free from intact animal proteins. This process effectively 'hides' the food from the pet's immune system, drastically reducing the chances of a histamine-mediated response or a delayed hypersensitivity reaction, which are the hallmarks of food-induced dermatological and digestive distress.
Dosage
Feeding amounts must be determined exclusively by your veterinarian based on your pet’s weight, body condition score, and metabolic needs. It is crucial to adhere strictly to these calculated portions, as free-feeding or overfeeding can alter the intended health outcomes. Always consult the specific bag label for weight-based guidance, and ensure fresh water is available at all times.
Administration
This diet should be fed as the exclusive source of nutrition for the period prescribed by your veterinarian. Gradual transition over 5 to 7 days is recommended to minimize stomach upset, mixing increasing amounts of the Anallergenic food with your pet’s previous diet until only the new food remains. Because the diet is highly specific, it is vital that all members of the household follow the feeding plan strictly, ensuring the pet does not have access to other household pets' food or human scraps.
Storage
Store the product in its original, sealed bag in a cool, dry place away from direct sunlight. To maintain freshness and prevent lipid oxidation, keep the bag tightly closed between feedings. It is recommended to use the product within the timeframe suggested by the manufacturer after opening, and avoid transferring the kibble to containers that previously held other types of food to prevent cross-contamination.
Contraindications
Royal Canin Anallergenic is not intended for pets with a known hypersensitivity to any of the ingredients in the formula. It should generally not be used in growing puppies or kittens unless specifically directed by a veterinarian to manage a confirmed severe allergy, as it may not meet the dense caloric and nutrient requirements for rapid development compared to standard growth diets. It is also not indicated for pets that do not have a suspected food-related component to their condition. Using this diet for animals with non-dietary health issues, such as primary metabolic disease or endocrine disorders, is not recommended, as there are more targeted therapeutic diets available for those specific clinical needs.
Interactions
There are no known pharmacological drug interactions with Royal Canin Anallergenic. However, because it is a diagnostic tool, the efficacy of the diet relies entirely on total exclusion. Administering flavored medications, chewable supplements, or heartworm preventatives that contain animal proteins can introduce potential allergens, which may compromise the results of a food elimination trial. Always check with your veterinarian before giving any additional treats or flavored medications while your pet is on this diet.
Side Effects
- Weight gain (if overfed)
- Gastrointestinal upset during the initial transition
- Picky eating due to the specific taste profile
- Stool consistency changes
