Key Facts
Calming through the gut — a different approach
Pawsd Gold Medal Review
This one works differently than everything else on this list. Instead of targeting the nervous system directly, Purina Calming Care uses the probiotic strain BL999 to influence behavior through the gut-brain axis.
Clinical studies show dogs on BL999 display calmer behavior over time. It's a long-term play — sprinkle one sachet on food daily and let it build over 6–8 weeks. Not for acute anxiety events, but excellent for dogs with a generally anxious baseline.
Backed by Purina's veterinary research team, this is one of the most scientifically rigorous calming products on the market.
