🐕 DULL COAT? DRY, BRITTLE FUR? YOUR DOG’S GUT MAY BE PART OF THE PICTURE.
A fascinating new peer-reviewed study looked at what happened when senior dogs were given compounds made by the beneficial bacteria Bacillus subtilis for just 28 days.
And the changes weren’t limited to their gut.
🔬 Under an electron microscope, the dogs’ fur looked smoother, more intact and less damaged, with fewer particles stuck to the surface. Their coat also showed a trend toward improved shine.
But what was happening on the inside was just as interesting.
The dogs digested protein and fiber better, produced more beneficial short-chain fatty acids, had lower f***l ammonia, and experienced significant changes in their gut bacteria.
Why might the gut affect the coat? The researchers suggest the healthier-looking fur could be connected to better nutrient digestion and changes in the gut microbiome—although this study wasn’t designed to prove exactly what caused the coat changes.
🦠 And here’s why this caught our attention: Dr. Karen Becker’s Primitive Probiotics™ contains OptiBiome® BS50® Bacillus subtilis. This new study looked at beneficial compounds made by Bacillus subtilis and adds another fascinating piece to what we’re learning about this unique probiotic species, the gut and whole-body health.
Healthy gut. Healthy dog. And potentially healthier-looking fur. 🐕✨
