š¶ DOG STRUGGLING WITH ANXIETY, REACTIVITY OR TROUBLE SETTLING? THEIR GUT MAY BE PART OF THE PICTURE. š¦ š§
A new 2026 peer-reviewed review is shining a spotlight on something most pet parents would never connect with their dogās behavior:
The gut microbiome.
The researchers highlight a randomized, placebo-controlled study of dogs given the specific probiotic strain Lactiplantibacillus plantarum LP815⢠for four weeks.
And what changed wasnāt just their gut.
𤯠Dogs receiving LP815⢠showed significant improvements in anxiety and aggression compared with placebo.
Even more interesting, activity monitors showed they settled faster after their owners left and had more consistent sleep.
And LP815⢠is one of the specific strains we chose for Dr. Beckerās Primitive Probioticsā¢.
Why does that matter?
Because with probiotics, STRAIN MATTERS.
You canāt assume every L. plantarumāor every probioticāwill produce the same effects. The review itself points out that probiotic research varies by strain, dose and duration.
This is why we didnāt formulate Primitive Probiotics⢠by simply chasing the biggest CFU number possible.
We selected specific researched strains in dogs that were designed to support the microbiome from multiple anglesāincluding LP815ā¢, a strain now being studied for something that goes far beyond digestion.
š¦ GUT ā BRAIN ā BEHAVIOR š§ š¶
For years, most pet parents have thought about probiotics for p**p and digestion.
Now scientists are investigating how specific probiotic strains may also influence the gutābrain axis, behavior, stress and sleep. And thatās a fascinating new chapter in canine microbiome research.
