Product details

Zylkene is a natural product that helps your dog or cat feel less stressed and return to their normal happy selves.

How it works:

Zylkene contains a natural product derived from a protein found in milk and works to calm your pet when they are feeling stressed or worried. The ingredients soothe their brain receptors, helping them to feel less stressed.

The Zyklene powder is packed into capsules which can be fed whole. If your pet refuses to swallow pills you can still give them this treatment. Simply open up the capsule and mix the powder in with your pet's food – they won’t even notice it’s there! It is designed to be fed to your pet once a day with a meal or treat.

Since Zylkene is a natural product that has little to no known side effects, you can feed it to your pet for as long as they need it. It can be given for short-term stress, possibly related to changes such as a house move or unfamiliar visitors. Or if your pet is adjusting to a more permanent change of circumstances (like being left alone during the day) they can be given Zylkene for longer periods until they settle down.

When to use it:

Animals react to stress in different ways, so it's important to learn how to spot the signs of it in your pet. Is your cat withdrawn or does she run away and hide? Is your dog more grumpy or being naughty? In scary or unfamiliar situations, pets can show that they are feeling stressed through bad or unusual behaviour.

If the cause of stress is temporary (such as a new visitor in your home or loud building work taking place) your pet will often return to normal once the problem’s removed. However, permanent changes such as a change in their routine or a new pet in the house might need you to take further action to reassure your pet.

  • Created from a natural product found in milk protein
  • Can be mixed with your pet's food for easy feeding
  • Designed to be given once a day either short or long-term

  • a good purchase
    It really helped my dog Bruce on firework nights

  • Great for the nervous dog
    I have been using these for a couple of years now, for my German Shepherd, who is scared of her own shadow, but mainly she hates the rustling through the tree's in my garden, when I know it's going to be windy, I start to give her some, and it does help, not completely, but sort of calms her a bit.

  • This seems to be the miracle worker we needed!
    Having tried everything else, and finding nothing from vets of any help, we have tried this for our greyhound who is terrified of the dark, loud noises, etc. After using them for two weeks we can't believe the improvement! Although not cheap by any means they are much cheaper than anything we have had from a vet, and they work! The delivery was also prompt and faultless.

  • A product that works.
    I have a dog that is frightened of storms, fireworks and even the sound of rain!! This is the second year I have used this product and can’t fault it. This calms her to a point that she can cope with whatever is upsetting her. Without this product she shakes and pants uncontrollably and follows me everywhere. I also use this product on one of my other dogs that is frightened of fireworks, again 100% result.
