Zylkene is a behavior supplement that helps dogs and cats relax, adapt to new locations, or cope with challenging situations — without making them drowsy.

Zylkene is:

• Clinically proven to help relieve stress without drowsy side effects
• Veterinarian recommended to help pets cope with challenging situations like thunderstorms, car rides, separation, and more
• Made with natural ingredients that are easy on sensitive stomachs with a lactose- and preservative-free formula
• The only brand to contain alpha-casozepine, a naturally occurring milk protein found in cow’s milk

When to use Zylkene:

• New places. Whether a pet is visiting the groomer, the vet, or moving to a new home, Zylkene can help them stay calm as they adjust to new environments. It is clinically proven to help pets cope with challenging situations without drowsy side effects.
• New situations. Fireworks, thunderstorms, and travel: few things are more stressful to pets. That’s why Zylkene is the perfect supplement to help pets stay calm without sedation, which makes new situations easier for them — and for owners.
• New people. Is company coming over? New baby in the house? With Zylkene, your pets can calmly adjust to new additions to the family — or just friends coming over to visit – without stressing out about it.

Zylkene can be given whole or opened at meal time and can be used for short- or long-term use. It’s the perfect supplement to help pets face life’s challenges.

For long-term use: Administer Zylkene for 1-2 months and then reassess the dog or cat. A pre-exposed animal may take longer to respond to Zylkene. Association with a behavior modification program and environmental management may help in these situations.
