OMG I cant praise this enough
If I could give this ten stars I would ! We have an old dog suffering from dementia. He is physically in excellent health but was suffering from severe stress and a condition named Sundown which was very horrible for him. He would become seriously agitated at night and pace in circles wimping. During the day he hardly responded and his eyes looked vacant and dull. We were at the point of having him pts. I remembered using the equine version on a horse and it worked to settle him in competition. So I gave it a go not really very hopefull. Within two days he was more settled. He continued to improve and has been on it now for a month and the Sundown no longer bothers him. His eyes are bright and he is now enjoying life. No longer dragging on walks and his appetite is healthy again. He is still an old dog but a normal old dog. No longer stressed and confused. No pacing and staring. I cant beleive the difference we have our dog back. He is fed the dose for a large dog although he is a labrador and med.

Amazing supplement to help with training!
I absolutely love this product. I was given this by my vets for my incredibly nervous rescue American Bull Dog x Staffy. She has extreme seperation anxiety and is nervous when it comes to every day normal tasks. It became such a strain on our lives and we found it impossible to train her. But after a few days of being on the medication, my dog had completely calmed down, less barking and nervousness and she's an absolute dream when out socialising with other dogs. Bare in mind this medication only works alongside strict training. They're not a quick solution. The medication clears my dogs mind enough to allow that training, if you're determined then the medication will work!

Nothing worked to calm my dog, He had massive anxiety at night, tried calming spray, rescue remedy, vet prescribed antidepressants and sedatives which just made him fall over. Tried Zylkene, worked within 3 nights, very excited to be able to sleep myself so ordered loads more, sadly I think my pooch has got used to it, we now have sleep about 4 out of 7 nights which is a bonus. He is a large dog on 450mg X2 . Worth a try, expensive but anything is worth a nights sleep.

Contact amazon?
The calming supplements work and calm our rough collier who has anxiety issues. However trying to contact amazon regarding the subscription costs is terrible! So I'm left with having to write my complaint on a review. I have tried different ways of making contact with customer services but end up going in circles. My complaint is we were charged £37.20 per packet of tablets(we ordered 3) when the cost without subscription is £34.97. We have a subscription and the cost should have been £29.72. Why have we been charged so much more!

Great but open the capsule 💊 not to be given whole
Doing ok so far watch out though !!!!!! I didn’t read the packet and you DO NOT GIVE AS A TABLET !! You break open the capsule 💊 and empty on food !! Didn’t do that 1st time so hope he will be ok 👌🏻 so stupid of me !! As they were capsules 💊 so I didn’t think ?

Easy to give as if it's a dog treat
It took the edge off a fear of fireworks without causing any drowsiness. A couple of my dogs will take the blue capsule whole, like a treat yet the older one spat it out so it got emptied into their food bowl instead.

They work if your dog suffers from anxieties
Great product they do exactly what there ment to calm your dog but price is a bit high for what they are now we will spend any money on our dogs but if they care for animals to help people that need this but can't afford this price or add a couple more to the batch because dogs suffer from anxiety and this works wonders in short term basis at there worst times like shaking or running all over the house scared because of idiots with fireworks and backfiring cars in purpose.

Super !
Bestes Mittel bei Feuerwerk oder Reise! Muss mindesten 1 Woche vorher gegeben werde ! Wirkt nicht bei allen Hunden - habe gelesen das liegt daran das Welpen die zu kurz gesäugt wurden die Inhaltsstoffe nicht verwerten können und die beruhigende Wirkung nicht optimal eintritt.

Ce produit a fait de l’effet dès les premières heures. C’est incroyable !

Decepcionada
Me parece surrealista que me llegue el producto como me ha llegado, totalmente decepcionante y cero confianza para administrárselo a mi perro.
