Overview
VetriScience Composure Chews are chicken flavored calming pellets built around L-theanine (as Suntheanine), a colostrum calming complex and vitamin B1, sized specifically for small dogs under 30 pounds in a 30 count bag.
This is a small breed dosing, not a general purpose calming chew scaled down. The title calls it clinically tested, though the data here does not include study details, so treat that as the brand's claim rather than something this listing substantiates independently.
- Formulated for small dogs under 30 lbs
- Contains Suntheanine brand L-theanine
- 30 count chicken flavored chews
- Marketed for storm and fireworks anxiety
Who it's for
Owners of small dogs, under 30 pounds, that get anxious around thunderstorms, fireworks or other predictable stressors. It is not sized for medium or large breeds.

Performance notes
L-theanine (Suntheanine) and the colostrum calming complex work on the nervous system's stress response rather than sedating the dog, paired with thiamine (B1) which is commonly used to support calm behavior.
