Zylkene is a calming supplement recommended by veterinarians. It helps dogs and cats manage stress and adapt to change. It also helps them cope with tough situations. Best of all, it does this without making them sleepy or sedated.
Zylkene is clinically proven and trusted around the world. It helps pets stay calm with a natural, gentle formula. This formula is safe for pets with sensitive stomachs.
Zylkene is formulated to help pets stay relaxed while remaining alert and responsive. It is:
Clinically proven to reduce stress without sedative side effects
Veterinarian recommended for anxiety related to travel, storms, fireworks, separation, and environmental changes
Made with natural ingredients, gentle on sensitive digestive systems
Lactose-free and preservative-free
Contains alpha-casozepine, a naturally occurring milk protein derived from cow’s milk
Alpha-casozepine helps control stress responses in the brain. It promotes calm behavior without changing your pet’s personality.
Zylkene is ideal for short-term or ongoing use during stressful or unfamiliar situations, including:
Vet visits, grooming appointments, boarding, or moving house can be overwhelming. Zylkene helps pets stay calm while adjusting to new surroundings—without sedation.
Fireworks, thunderstorms, car travel, and loud noises are common anxiety triggers. Zylkene supports relaxation while allowing pets to remain fully alert.
Whether welcoming guests, introducing a new baby, or adding another pet to the household, Zylkene helps pets adapt calmly to changes in their routine.
Zylkene is administered once daily and can be given whole or opened and mixed with food. It may be given during or after mealtime, making it simple to use even for fussy pets.
For best results, begin administration 1–2 days before a known stressful event. Some pets may benefit from starting 5–7 days in advance, as advised by a veterinarian.

I am happy with the heart guard & frontline plus . Glad I discovered you online retail store.
My dog finally has relief from scratching and is sleeping like a baby.
Received the product quickly. I did not remember that I had set up auto-ship so I ordered Simparica Trio again. I now have enough of the medication to use through December 2026. Please do not send the auto ship in September. Will not need another box until January 2027. Very happy with your service but not so happy with my terrible memory.
