Hill’s symposium puts the gut-skin axis in the CE spotlight: full analysis

Version 2

Hill’s Pet Nutrition is using its 2026 Global Symposium to spotlight one of the more closely watched ideas in companion animal dermatology: the gut-skin axis. The free global CE event, Healthy Skin Starts from Within, is scheduled for June 24-25, 2026, via Hill’s Veterinary Academy, with an in-person meeting in Phuket, Thailand, and on-demand access after the livestream. According to Hill’s event materials and Veterinary Practice News, the agenda includes more than 10 experts and a strong emphasis on how nutrition, the microbiome, and dermatologic health intersect in dogs and cats.

The focus is a natural extension of Hill’s recent educational programming. In 2024, the company’s Global Symposium centered on the broader gut microbiome-organ connection, including links between the gut and the skin, brain, and kidneys. This year’s narrower emphasis suggests the company sees dermatology, and especially allergic skin disease, as a clinically relevant setting where microbiome science and therapeutic nutrition may be easier for general practitioners to apply.

The 2026 agenda is built around that idea. University of Florida’s Domenico Santoro is slated to open with a session on skin-microbe interactions in allergic disease. Sara J. Ramos will review ICADA 2023 recommendations for canine atopic dermatitis and discuss pitfalls in elimination diet trials. Camille Torres will cover skin barrier support and the evidence around prebiotics, probiotics, and postbiotics, while Hill’s scientist Alyssa Toillion is scheduled to present on hydrolyzed protein food with a specialized prebiotic fiber blend and its effects on pruritic dermatitis and stool quality in adult dogs. Other sessions broaden the frame further, including Sun-A Kim’s talk on the gut-skin-brain axis and behavior in dermatology patients, plus feline-focused sessions from Stefano Borio and Elise Robertson.

That agenda lands at a time when the science around canine atopic dermatitis is increasingly describing disease as more than a surface-level skin problem. Recent reviews indexed in PubMed describe canine atopic dermatitis as a complex inflammatory disease involving epidermal barrier dysfunction, microbiome disruption, immune abnormalities, and allergic sensitization. ICADA also continues to serve as a major reference point for clinicians managing allergic disease in dogs, which helps explain why updates tied to its recommendations are featured prominently in the program.

Industry coverage has framed the symposium as one of the larger free global education offerings for veterinary professionals, with multilingual access and rebroadcasts for different regions. Hill’s event page says the livestream will be available in English, Japanese, and Korean, with real-time translations and the possibility of CE credit where available. That global format matters because dermatology and nutrition are both areas where practice patterns vary widely by market, especially around diet trials, microbiome supplements, and how aggressively clinicians integrate nutrition into chronic skin case management.

Why it matters: For practicing veterinarians, the real significance is less the event itself than the signal it sends about where companion animal dermatology education is heading. Cases involving pruritus, recurrent otitis, food-responsive disease, and chronic atopic dermatitis already consume substantial appointment time. A gut-skin framing encourages clinicians to think more deliberately about barrier support, elimination diet design, gastrointestinal comorbidities, and the evidence base behind microbiome-targeted interventions, rather than treating skin signs in isolation. AAHA’s nutrition guidance has already pointed to the microbiome as a meaningful clinical target affected by diet, antibiotics, prebiotics, probiotics, and even fecal microbiome transfer, though the strength of evidence varies by use case.

There’s also a practical business and communication angle. Pet parents increasingly arrive with questions about “microbiome health,” novel diets, and supplements, often influenced by consumer wellness language that outpaces the evidence. A symposium built around the gut-skin axis may help clinicians separate what is biologically plausible, what is supported by published veterinary data, and what remains more hypothesis than standard of care. That distinction is especially important in canine atopic dermatitis, where multimodal management remains the norm and no single nutritional intervention replaces a full diagnostic and treatment plan. This is an inference based on the program topics and current review literature, rather than a stated claim from Hill’s. (na.hillsvna.com)

What to watch: The next question is whether Hill’s and its speakers translate the gut-skin concept into concrete protocols clinicians can use, particularly around diet trial execution, case selection for microbiome-directed nutrition, and integration with established atopic dermatitis guidance when the symposium begins on June 24, 2026.
