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.

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.

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.
