Zylkene Calming Chews
Keep your dog relaxed and confident with Zylkene Calming Chews, specially formulated to support emotional well-being during stressful moments. Whether it’s travel, vet visits, fireworks, or changes in routine, these tasty chews help your dog cope naturally and calmly.
Each chew contains alpha-casozepine, a protein derived from milk, which gently signals the brain to promote relaxation without causing drowsiness. Unlike sedatives, Zylkene works subtly, helping your dog feel balanced and comfortable while staying alert and playful.
Zylkene chews are easy to administer, give them directly as a treat or mix with food. They can be used for short-term support during specific stressful events, or daily for longer-term emotional balance. With consistent use, many dogs show calmer behaviour and reduced stress responses, making everyday life more enjoyable for both pets and owners.
