Hypoallergenic Diets in Dogs and Cats: 2026 Update
Food allergy affects up to 33% of atopic dogs and 22% of pruritic cats. The elimination diet remains, in 2026, the only validated diagnostic tool for confirming food allergy, as no serological or salivary test can confirm it. Discover in this comprehensive article the immunopathological mechanisms and current diagnostic strategies, from the choice of hypoallergenic food to long-term management. Grain-free or insect-based diets, particularities of these diets in cats, the role of the provocation test, and much more.
Numelvi (Atinvicitinib) in Dogs: 2026 Monograph
Canine atopic dermatitis (CAD) affects 3 to 15% of the canine population. The arrival of atinvicitinib (NUMELVI, MSD Animal Health), a selective second-generation JAK1 inhibitor authorised in Europe in July 2025, has altered the therapeutic landscape of this condition. This review details updated data, from the molecular mechanism to management strategies.
Zenrelia (Ilunocitinib) in Dogs: 2026 Monograph
Canine atopic dermatitis affects 10 to 15% of the global canine population and constitutes one of the primary reasons for consultation in veterinary dermatology. In the face of this condition, new treatments are emerging with an excellent benefit/risk ratio. A comprehensive overview of Zenrelia (ilunocitinib), which is the first of the new Janus Kinase inhibitors to have been brought to market following oclacitinib (Apoquel).

Complete update on Malassezia in dogs and cats
Yeasts of the genus Malassezia constitute lipophilic fungal agents that have evolved as cutaneous commensals and opportunistic pathogens across various mammalian and avian species. Their involvement in canine and feline dermatological and otological conditions represents a daily clinical challenge for veterinary practitioners on a global scale. At the recent NAVDF congress in Orlando, our colleague Ross Bond, a world specialist on the subject, had the opportunity to provide a comprehensive update, covering pathogenic, diagnostic and therapeutic aspects.
Feline Sporotrichosis: Clinical Aspects and Epidemiology
On the occasion of the last NAVDF congress held in April in Orlando, our colleagues Drs. Flavia Clare and Clarissa Souza provided a comprehensive review of sporotrichosis, a rare and largely unknown fungal dermatosis.
Dermatoses of the nasal planum in dogs
Dermatoses of the canine nasal planum represent a unique diagnostic challenge for the veterinary practitioner, despite their relative frequency in dermatological consultations. The etiological diversity of these conditions, combined with the frequent overlap of clinical presentations, requires a rigorous methodical approach that our colleague Laura Ordeix presented at the last ESVD congress held in Bilbao, Spain.
2025 Update on the Etiopathogenesis of Canine Atopic Dermatitis
Canine atopic dermatitis represents a major clinical challenge in contemporary veterinary medicine, with a prevalence that continues to increase in urban canine populations. This chronic inflammatory skin condition, characterized by intense pruritus and recurrent cutaneous lesions, significantly affects the quality of life of animals and constitutes a frequent reason for consultation in veterinary dermatology. At the recent NAVDF congress in Orlando, our colleague Rosanna Marsella had the opportunity to provide a comprehensive 2025 update on the etiopathogenesis of Canine Atopic Dermatitis.
Canine cutaneous calcinosis: Etiologies and treatments
Cutaneous calcinoses represent a major diagnostic and therapeutic challenge in canine veterinary dermatology. These conditions, characterized by abnormal accumulation of calcium salts in dermal and hypodermal structures, require a rigorous clinical approach based on precise understanding of their distinct pathophysiological mechanisms.
Press review
A series of three cases of feline sarcoptic mange in Poland.
Sarcoptic mange is an ectoparasitic disease caused by the arthropod *Sarcoptes scabiei* from the family Sarcoptidae. While this parasite has been isolated in several domestic and wild mammal species, infestation in cats is considered extremely rare.
Retrospective study on 28 cases of canine lichenoid psoriasiform dermatosis
Psoriasiform lichenoid dermatosis constitutes an unusual cutaneous manifestation in dogs, closely associated with the administration of calcineurin inhibitors and complicated by staphylococcal infection. This dermatological condition, characterized by distinctive hyperkeratotic lesions, raises fundamental questions concerning the complex interactions between therapeutic immunomodulation and cutaneous pathogens.
Ultrasound-guided intralymphatic immunotherapy in canine atopic dermatitis: a retrospective study of 109 cases.
Canine atopic dermatitis (CAD) represents a major therapeutic challenge in veterinary dermatology, often requiring long-term management. Intralymphatic immunotherapy (ILIT) has progressively emerged as a promising alternative to conventional treatments, offering encouraging results in both human and veterinary medicine.
Immune-mediated skin diseases in cats: Part 1.
Immune-mediated skin diseases in cats, although rare, present a diagnostic and therapeutic challenge for veterinary practitioners. These pathologies, characterized by a dysregulation of the normal immune response, can manifest with variable clinical signs, ranging from erythema and alopecia to skin erosions, with or without pruritus, often mimicking other more common dermatological conditions.
Review article
Feline Acne: Diagnosis, Treatment and Therapeutic Perspectives
Feline acne, a common skin condition in felines, presents a significant diagnostic and therapeutic challenge for clinicians. Studies, although limited, have highlighted various clinical and histopathological aspects, emphasizing the need for a personalized approach.
Etiology and Management of Canine Pododermatitis
Canine pododermatitis does not constitute a single nosological entity, but rather represents a complex and multifactorial cutaneous reaction pattern, resulting from a dynamic interaction between primary causes, predisposing factors and perpetuating elements. This synthesis report aims to provide a comprehensive, nuanced and updated analysis of the etiology, pathophysiology and therapeutic strategies of canine pododermatitis.
Importance of Methicillin-Resistant Staphylococci in Veterinary Dermatology
Veterinary dermatology has undergone a radical transformation over the past two decades, marked by the emergence and global spread of methicillin-resistant staphylococci (MRS). Once considered simple bacterial infections that responded predictably to treatments, canine pyoderma is now at the center of an antimicrobial resistance crisis.
