Performance notes
The Colostrum Calming Complex and L-theanine combination is a different approach from the melatonin and valerian root chews common in this category, and the medium and large breed sizing means dosing is calibrated for bigger dogs rather than a universal small to large range.
What buyers say
Roughly 2,400 reviews at a 4.1 star average and about 500 units bought in the past month suggest a steady, moderately sized customer base for this specific medium and large dog formula.
No, the active ingredients listed are thiamine, L-theanine, and a Colostrum Calming Complex rather than melatonin or valerian root.
Is this suitable for small dogs?
This formula is sized and marketed specifically for medium and large dogs, so a small dog formula would likely be a better fit for smaller breeds.
What situations is this meant to help with?
The label points to thunder, fireworks, and barking as common triggers this chew is meant to support, as a behavior aid rather than a medical treatment.
