Calming chews for dogs that last through the whole storm. VetriScience Long Lasting Calm & Confident starts working in about 30 minutes and supports calm behavior for up to 8 hours — so you're not re-dosing halfway through a thunderstorm, a road trip, or a workday away from home.
How these dog anxiety chews work

Colostrum Calming Complex™ — supports stress response and cognition
-
L-Theanine — promotes relaxation and reduces irritability
-
Thiamine (Vitamin B1) — acts on the central nervous system to encourage calm

Shoden® Ashwagandha — a multi-patented extract clinically studied for stress relief and sleep quality in dogs

When to use calming chews for dogs
Thunderstorm and firework anxiety. Separation anxiety and crate stress. Car rides, flights, and boarding. Vet and groomer visits. Moving to a new home, new-baby or new-pet introductions, and reactive dogs working through a training plan. Use daily for ongoing support or situationally before a known trigger.
Feeding directions
Give approximately 30 minutes before the stressful event, or daily for consistent support. Follow the label serving guide for your dog's weight. For very anxious dogs, the serving may be doubled on high-stress days.
