A pet’s life is full of new people, new situations, and new challenges. With Zylkene, pets can find balance when life gets stressful.

Zylkene is a behavioral supplement that helps dogs and cats relax, adapt to new places, or cope with challenging situations — without causing drowsiness.

Benefits of Zylkene

• Clinically proven to relieve stress without drowsy side effects
• Veterinarian recommended for use during thunderstorms, travel, separation, and other challenges
• Made with natural ingredients; lactose- and preservative-free — gentle on sensitive stomachs
• The only product containing alpha-casozepine, a naturally occurring milk protein derived from cow’s milk

When to Use Zylkene

• New places: going to the groomer, vet, or moving — Zylkene helps maintain calm during transitions
• New situations: fireworks, storms, travel — Zylkene helps pets stay relaxed without sedation
• New people: new baby, visitors, or guests — Zylkene helps pets adjust without stress

Begin administering Zylkene 1–2 days before the expected event or environmental change. Some animals may require earlier administration (5–7 days). Administer before the pet can anticipate the change.

Long-term use:

Administer Zylkene for 1–2 months, then re-evaluate the pet. Animals with previous exposure to stressors may take longer to respond. Combining with behavioral therapy and environmental management is recommended.
