🦠 DOGS BENEFIT FROM DOG-DERIVED PROBIOTICS.
A new peer-reviewed review published in Frontiers in Veterinary Science highlights something you may not know: most pet probiotics🐾 still use bacterial strains originally isolated from humans.🧍But growing research suggests dog-derived probiotic strains can be a better fit for a dog’s unique digestive system.
Researchers found that probiotics isolated from healthy dogs attached to a dog’s intestinal lining much better than strains from other species. Why does that matter? The longer beneficial bacteria can remain where they’re needed, the more opportunity they have to support the gut barrier, communicate with the immune system, and help maintain a healthy microbiome. The review also explains that probiotics have evolved alongside their host species, making dog-derived strains naturally better suited to life inside a dog’s gut.
This is important because roughly 70% of your dog’s immune system is associated with the gut, and growing evidence links the microbiome not only to digestion, but also to allergies, skin health, metabolism, kidney health, and even the gut-brain axis. Supporting the right bacteria may be one of the most important things we can do for long-term health.
That’s one reason Dr. Karen Becker formulated Primitive Probiotics™ with multiple canine-derived probiotic strains, alongside Saccharomyces boulardii, beneficial soil-based bacteria, and the clinically studied LP815™ strain to support digestive, immune, and microbiome health. While no probiotic is a cure-all, this review reinforces the growing idea that matching probiotics to the species they’re designed for matters.
