The generalized pruritus had been treated with barrier clothing, oral systemic steroids, and Atopica. The pet parent reported that the patient has not been able to be medicated successfully, is generally comfortable although historically the pruritus had waxed and waned.

Treatment of Dermatophytosis in Dogs and Cats in 2026: Available Drugs and Updated Protocols
Dermatophytosis is a superficial infection of the skin and hair coat caused by keratinophilic fungi of the genera Microsporum, Trichophyton and Nannizzia. In dogs and cats, Microsporum canis is by far the dominant agent. The disease is contagious, infectious and transmissible to people, which gives it a place of its own in the dermatology consultation. The practitioner treats an animal and protects a household.

Hyperglobulinemia in a Cocker Spaniel with Multiple Cutaneous Nodules
“Teddy” is a 10 year old male neutered cocker spaniel presented by the owner for multiple cutaneous nodules of 3 months’ duration. He has a chronic history of pancreatitis well managed with a prescription low-fat diet.

Feline Cutaneous Herpesvirus: Review and Updates 2026
Feline viral dermatoses have long remained in the background, partly due to the lack of easily identifiable causative agents and partly due to the absence of specific treatments. Long known for its respiratory and ocular manifestations, feline herpesvirus type 1 is now recognized as a cause of ulcerative dermatitis, primarily affecting the bridge of the nose.

Well-Demarcated Alopecia on the Dorsum of a DSH
Pixie” is a 5y FS DSH who presented for a history of well-demarcated alopecia on the dorsum of more than a year’s duration. The affected area of the dorsum is not especially pruritic that owner has noticed; Pixie occasionally licks her dorsum, but can only reach about the caudal third of the affected area with her tongue when grooming herself.
Beyond Expression: An Inflammation First™ Approach to Managing Recurrent Anal Sacculitis
Recurrent anal sac disease is surprisingly common – and easy to underestimate. It is one of the few chronic conditions in small animal practice that is routinely minimized, often distilled down to a quick “just do their glands” during a busy appointment. Because manual expression typically provides immediate relief, it is understandable that owners – and sometimes even clinicians – assume the problem begins and ends with mechanical emptying. Maybe add a little fiber, consider a probiotic, and see the dog next month.

Use of Nexgard and Nexgard Spectra in Canine Dermatology
In veterinary dermatology, afoxolaner, an isoxazoline administered orally in dogs, has transformed the management of demodicosis, sarcoptic mange, and infestations by fleas and ticks in particular. This article provides a comprehensive review ranging from pharmacology to the latest publications, covering both Nexgard and Nexgard Spectra.
News and Update on Canine Symmetrical Lupoid Onychodystrophy
Symmetrical lupoid onychodystrophy affects all claws on all four limbs within a few weeks, turning the focal detachment of a single claw into a painful generalized condition. Primarily described in the Gordon Setter with a prevalence reaching 12.6% and in the Bearded Collie where it is on the rise, it remains the most common immune-mediated nail disorder in dogs. This review details recent data, from the genetic substrate to current therapeutic strategies.
Perianal and Perigenital Dermatoses in Dogs
The perianal, perineal, and perigenital regions of the dog represent an anatomical territory whose complexity is often underestimated in routine consultations. Yet the dermatoses occurring in these areas are common, polymorphic, and capable of generating significant morbidity. Intractable pruritus, chronic pain, ulcerative or nodular lesions: these are all clinical presentations that require a structured diagnostic approach. At the most recent ESVD congress, our colleague Elisa Maina from the University of Bern provided a comprehensive overview of these various dermatoses.
