Zylkene Capsules are a complementary feed designed to help cats and dogs manage stressful situations. Zylkene contains a natural product derived from casein, a protein in milk, that is well known to promote the relaxation of newborns after breastfeeding. Zylkene is palatable and easy to give: simply mix with food or give the whole capsule. It can be given daily and is both preservative and lactose free.

  • Zylkene Capsules contain a palatable, water soluble powder that appeals to both dogs and cats
  • Zylkene Capsules can be given whole or can be opened and the powder mixed with food, treat or liquids
  • Water should be available at all times
  • As Zylkene is taken orally, it is present wherever the pet goes, both inside and outside the house

Since its launch Zylkene has become a familiar product for veterinarians, behaviourists, nurses and pet owners world wide. It helps pets cope when facing unusual and unpredictable situations and can be used before occasions such as a change in their normal environment.

When to use Zylkene

Zylkene can help support dogs and cats in situations where they find they need to adapt their behaviour to cope. These can include kennel and cattery stays, moving house, the arrival of a new pet or baby, sudden noises such as fireworks, travel or festivities. Many cats do not cope well in a multi-cat household, so Zylkene can help with the introduction of a new cat.


Zylkene is easy to give in one daily intake. The capsules contain a palatable, water soluble powder that appeals to both dogs and cats. They can be given whole or opened and the powder mixed with food, treats or liquids. Since Zylkene is taken orally and ingested, it is present wherever the pet goes, both inside and outside the house. Water should always be available to your pet.

Zylkene comes in three strengths:

  • Zylkene Capsules 75mg (30 capsules)
  • Zylkene Capsules 225mg (30 capsules)
  • Zylkene Capsules 450mg (30 capsules)

Dosage Guide

For short term use: Begin administration 1-2 days before the predicted event or change in environment. Some animals may need earlier administration (5-7 days).

For long term use: Start giving Zylkene for one month then reassess the pet. Association with a behaviour modification program may help in these situations.

    Always extra happy with the service from pet chemist on line! I have used Zylkene for my little Bichon for some time and 4 out of 5 of the bottles contain only 29 capsules although they are suppose to contain 30. I always seem to have a capsule waiting for the next bottle (which again usually contains only 29 to finish ) to use up the one capsule left over. Not a major problem but just a little annoying.

    My min schnauzer gets quite anxious, she has 1 /75mg Zylkene capsule daily and 2 night prior to any out of the ordinary events the next day keeps her calm, she is much happier since being on this product.

    Zylkene 450mg tablets

    Posted by Stacey O'Regan on 19th Oct 2020

    Great product that is often recommended by veterinarians. Made a huge difference to my anxious dog. By far the best price I could find to purchase the tablets and always fast shipping whether express or not. Definitely would recommend even as a trial for an anxious pet

    Posted by Ashley Southam on 28th Sep 2020

    I have been using these on my assistance dog for about 2 months and have noticed a huge difference in his anxiety levels and he seems so much more calmer and focused on his duties that help me in daily life.

    My 13yr old Bengal Coco suffers from anxiety & after 1 week taking half the lowest strength due to her weight she is lots calmer & not pulling her fur out & or over grooming, hoping it will stop her peeing on the furniture in time.
