Zylkene made all the difference for our older dog Mia.
We brought home a new puppy (Mara) and Mia really struggled. After starting her on Zylkene🩵 we noticed a positive change within just a few days. She became calmer, more relaxed, and seemed much happier in herself.
The real breakthrough was when she began to show interest in the puppy - even letting her lie next to her and rest her head on her.

I stumbled on a mention of Zylkene🩵 online, and ordered some immediately. Within a week we could see Rua was grooming less, within a month or so we could see his hair was starting to grow back. Now, almost 10 months on and his tum and legs are as fluffy as they ever were. Your product truly changed our lives, and brought my happy, fluffy boy back. We will always be grateful to you.

Tofu used to panic when being left alone - shiba screams, pacing and sometimes even destructive.
We worked with a behaviourist who introduced us to Zylkene🩵, along side training, he now stays calm, settles on his bed while we not around, it's nice to be able to leave the house without feeling worried.

Zylkene🩵 really helped Smokey during fireworks. She’s always been very jumpy with loud noises and usually disappears for the whole evening. After just a few days on Zylkene🩵, she was much more settled and noticeably calmer overall.
It was such a relief to see her more relaxed and not so on edge. I’ll definitely keep using it during fireworks time to help her feel safe and comfortable.

We adopted our big bear Loki at 9 and quickly learnt that he hates both loud bangs and car journey. He would have accidents, pant heavily and the howling was unreal!
Thanks to Zylkene🩵 and desensitisation training, he's much more settled and relaxed with them - it’s made life a lot easier for him, and us.

I’ve seen first hand how behaviour problems can impact animals’ lives, not just in practice but at home too. My own dog, Rizzo, is a rescue who came to us with some pretty significant behaviour challenges. She’s in the photo with me, and she’s a daily reminder of how patience, understanding, and the right support, from products like Zylkene, can make a huge difference to both pets and owners.
