Having had 2 dogs that suffered with CCD (doggy dementia) I like to pass along any new science on the subject.
Watching your dog become confused😵💫🐶, pace the house at night🌙, forget familiar people, have accidents indoors, or seem like they’re “slipping away” is one of the hardest parts of loving a senior dog.
Published in the peer-reviewed Journal of the American Veterinary Medical Association (JAVMA), this 90-day prospective clinical study evaluated both cognitive🧠 function and gut🦠 microbiome changes in aging dogs🐶 with dementia.
In this study, dogs with dementia received one oral f***l microbiota transplant (“poop”) capsule💩💊 twice a day for 90 days. Among the dogs that responded, dementia scores improved by nearly 60%, with many owners reporting less confusion, better sleep, reduced anxiety, and improved memory. The treatment was well tolerated, adding to growing evidence that supporting the gut microbiome may also help support the aging brain.
While FMT isn’t widely available or affordable for most families, there are still ways to support your dog’s gut-brain connection every day.
Primitive Probiotics™ combines canine-derived, clinically studied, and soil-based probiotic strains, including L. plantarum LP815, L. rhamnosus GG, and B. bifidum—beneficial bacteria that have been studied for their role in supporting the gut-brain axis, promoting a healthy inflammatory response, influencing neurotransmitter activity, reducing anxiety, and supporting cognitive health.
It’s not a replacement for FMT, but it is a simple, affordable way to help nourish the gut microbiome that plays such an important role in your dog’s overall health, including the brain.
