A new peer-reviewed, first-of-its-kind study found that dogs with atopic dermatitis (skin allergies) have significantly lower levels of all three key short-chain fatty acids (SCFAs): acetate, propionate, and butyrate, compared to healthy dogs.🦠 These gut-derived compounds are produced by beneficial bacteria and play a critical role in protecting the gut lining, balancing the immune system, and reducing inflammation. Lower SCFA levels suggest that dogs with allergic skin disease may have an altered gut environment that produces fewer of these protective compounds.
Similar patterns are seen in people with atopic dermatitis (eczema), where reduced SCFAs are common and may even help predict disease development. One of SCFAs’ most important functions is nourishing the cells that line the gut, helping maintain a strong intestinal barrier and reducing the risk of unwanted compounds leaking into the bloodstream. Without adequate SCFA-producing bacteria, overall gut, immune, and skin health can suffer.
Feeding dogs minimally processed, high-fiber foods, resistant starches, and targeted probiotics or prebiotics can help beneficial bacteria thrive and increase SCFA production. That’s why Dr. Becker developed PRIMITIVE PROBIOTICS™—a science-driven approach to supporting your dog’s microbiome using specific strains, including Lactobacillus species and Bifidobacterium bifidum, that help contribute to SCFA production and a healthier, more resilient gut.
