This 2026 update provides a comprehensive review of Cutaneous Adverse Food Reactions (CAFR) in dogs and cats. With a prevalence of 18–29% in pruritic pets, the 8-week elimination diet remains the diagnostic gold standard, as serological tests lack clinical reliability. This report explores IgE and T-cell mediated pathways, allergen hierarchies (beef, dairy, poultry), and the critical issue of cross-contamination in 40% of OTC diets. From selecting between home-cooked meals and advanced hydrolyzed diets ($< 3$ kDa) to performing the essential oral food challenge, this expert guide delivers rigorous clinical strategies for long-term dermatological and GI management.

Cette mise au point 2026 détaille la prise en charge des Réactions Cutanées Indésirables aux Aliments (RCIA) chez le chien et le chat. Face à une prévalence de 18 à 29 % chez les animaux prurigineux, le régime d’élimination de 8 semaines reste le seul "gold standard" diagnostique, les tests sérologiques manquant de fiabilité. L'article analyse les mécanismes IgE et T-médiés, la hiérarchie des allergènes (bœuf, produits laitiers, poulet) et l'impact des contaminations croisées dans 40 % des aliments du commerce. Du choix entre régimes ménagers et hydrolysats de haute technologie ($< 3$ kDa) jusqu’à l’épreuve de provocation indispensable, ce guide offre une expertise clinique complète.

Feline plasma cell pododermatitis is a rare inflammatory dermatosis, accounting for less than 1.5% of dermatological consultations. It is characterized by soft, purplish swelling of the pads—commonly referred to as "pillow foot"—caused by a massive infiltration of mature plasma cells into the dermis. This mysterious condition can occur at any age but primarily manifests between 4 and 7 years of age, with no clear breed predisposition or sex predilection.
