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.

    My dog has extreme anxiety after fireworks thrown into the yard. was hyper vigilant, barking at the smallest noise. Zylkene has been great at reducing the anxiety, allowing my dog to relax enough to start a desensitising process.

    not sure if it is working. Used for one month so far - my cattle staffy cross still goes bonkers at triggers . Maybe it is just the breed... will try for another month.

    A good product for my anxious cat. One half capsule daily and she's much happier and calmer.

    This is a great product for anxious dogs. It does take a couple of days to kick in though.

    Hoping it will do what Valium can't do

    I highly recommend this product. If you have an anxious furbaby, these tablets defiantly help. Even if you're moving, these tablets are a good temporary measure to help keep your fur family member as calm as they can.
    I would also say to keep a eye on your animals sleeping habits, it took us a few months to find a good balance but, now we have, it's even better :)
