Frequently Asked Questions

Do calming treats actually work for dogs?

Yes — ingredients like L-Theanine, alpha-casozepine (Zylkene), and Ashwagandha have clinical evidence for reducing anxiety in dogs. Results vary by dog and anxiety type. They work best as part of a broader management plan (training, enrichment, vet guidance).

How long before an event should I give calming treats?

For situational anxiety (storms, fireworks): give 30–60 minutes before the event. For ongoing daily anxiety (separation): give daily as part of routine. Zylkene can also be started 2–3 days before a planned stressful event for better effect.

Are calming chews safe for daily use?

Yes — natural calming chews using L-Theanine, Ashwagandha, and Passionflower are safe for daily use. Always follow the recommended dose on the label and consult your vet if your dog is on other medications.
