Adverse food reactions are a common consideration in small animal practice and may present with dermatological and/or gastrointestinal signs. These reactions can be triggered by a variety of dietary ingredients, and no single protein source can be universally identified as the cause.
Within the Vet Expert portfolio, there are selected veterinary diets formulated without chicken, designed to support nutritional management in cases where the exclusion of chicken is clinically indicated and recommended by a veterinarian.
Food-related reactions: the importance of veterinary diagnosis
Clinical signs that may be associated with adverse food reactions include:
- Chronic pruritus with no apparent parasitic cause
- Recurrent skin lesions or inflammation
- Frequent external otitis
- Persistent gastrointestinal disturbances
⚠️ However, clinical signs alone are not sufficient to diagnose a food allergy or to identify a specific dietary trigger. An accurate diagnosis requires assessment by a qualified veterinary professional, who may recommend appropriate diagnostic procedures and/or a controlled elimination diet to support identification of the underlying cause.

Alternative protein sources in chicken-free formulations
Selected Vet Expert diets formulated without chicken include:
- Insect protein (Hermetia illucens), considered a novel protein source;
- Lamb, fish or rabbit, depending on the specific formulation;
- Monoprotein diets, where appropriate, to support dietary control.

Nutritional role of chicken-free diets
- Supports dietary strategies for managing adverse food reactions;
- Helps limit exposure to selected protein sources when indicated;
- Contributes to digestive tolerance and skin health;
- Provides complete and balanced nutrition when used as directed
Vet Expert diets formulated without chicken are intended to be used under veterinary supervision, as part of an evidence-based and individually tailored nutritional plan.
