Vetoquinol Zylkene the non-drowsy formula uses alpha-casozepine, a natural ingredient found in cow’s milk, to help balance the stress reactions of dogs and cats safely and with no tranquilizing or sedating effects. Milk-sourced alpha-casozepine is known to promote relaxation in babies, and it works in a similar way for your pet, giving him a sense of comfort and contentment to help him cope with stress or adapt to new situations. It’s perfect for most pet stressors like loud noises, visits to the vet or groomer, as well as unfamiliar people and places. Plus, it’s free of lactose and preservatives, making it ideal for sensitive tummies.

  • The only veterinary supplement formulated with alpha-casozepine, a natural ingredient from cow’s milk with calming properties to help relax cats and dogs.
  • Non-drowsy formula provides a sense of calm and contentment without tranquilizing or sedating your pal.
  • Perfect to use before or during stressful situations, including moving, adapting to new people or new places, traveling, vet visits, and for behavior training.
  • Free of lactose and preservatives, so it’s ideal for pets with sensitive tummies; used by veterinarians and animal behaviorists worldwide.

    Our vet recommended this product
    May 21, 2017
    Our vet recommended this product from the feedback she had been receiving from her patients, so we gave it a try and as skeptical as I am, the product actually worked. My Yorky is cursed with anxiety issues, but since taking this product, he's calmed down and hasn't had anymore outbreaks. I would have never believed it if I hadn't seen it with my own eyes.
    It actually works! No cons!
