A natural way to help pets cope with stressful situations.

Zylkene is a calming supplement that contains a natural ingredient derived from a protein in milk called casein that has clinically proven calming properties to help relax cats and dogs. It is a peptide (protein) molecule, well known to promote the relaxation of new-borns after breastfeeding by delivering ‘calming messages’ to the brain via the body’s natural ‘messenger’ system (scientifically known as Neurotransmitters).

Launched in April 2008, Zylkene has become a valuable support for veterinary surgeons, behaviourists, nurses and pet owners for use in helping pets cope when facing unusual and unpredictable situations or before occasions such as a change in their normal environment.

Zylkene can be administered in multiple ways – so you can tailor to suit your pet’s needs

Zylkene Capsules - 20 per pack

Zylkene capsules are a tasteless powder which can be given in multiple ways; it can be mixed in with food or dissolved with water – great for fussy eaters.

Zylkene Chews - 14 per pack

What’s the best option for my pet?

Both Zylkene capsules and chews have the same calming effect to help your pet cope. Consider if your pet struggles taking capsules or not – or if they are treat orientated and would enjoy a chew.

Common situations that can be stressful to your dog or cat and where Zylkene can help:

Short Term:

Begin adminstration one or two days before the predicted stressful event or change in the environment.

Long Term:

Give Zylkene to the dog or cat for one month then reassess their behaviour, continue if needed.

Amanda Skinner and Ollie

“We have used Zylkene since Ollie was a puppy, he's a big nervous wreck when it comes to vet visits and Zylkene is our saving grace! We love how easy it is to administer, just pop open the capsules and mix it with his food. He doesn't take tablets well so Zylkene is absolutely perfect! We always make sure we have some in the house just in case and wouldn't be without it, we've tried other calming products but this is by far the best!!”

Jackie Flack and Lionel

“We adopted a 9 year old lurcher last year and because of his previous lifestyle he suffered with severe separation anxiety, especially at night time. Despite allowing him to sleep in the same room as us he still panicked when he did not have contact with us. We have been using Zylkene now for a couple of weeks and the difference is amazing, we first used 1 tablet a day but now only need 1 every other day and we are hoping to reduce further. He is so much more relaxed now and we are all getting much needed sleep!”
