We got back from your horse live, and again fireworks going off, given k9 calming cookies to my brothers dog, and the difference is incredible! So chilled and calm, can’t wait to try the equine ones next week when I back my boy! Thank you so much guys.

It's fair to say our horse is a sensitive sole since having gastric ulcers! Grass, the weather and even coat change all effect him despite scoping clear. It is very clear to see when Hustlers tummy isnt feeling right. GastroPremier has been an absolute game changer for us and would not be without it. I cannot thank Camilla enough for all her help and support x x

Knowledgeable team who were quick to respond to queries. I've been using the calming powder for a few months now and it's made rehabbing my welsh A a much more pleasant experience for her.

After my 17 year old dressage horse became incredibly stiff, we put him onto the Premier Performance JointFlex. It took him from hardly being able to step under with his hind legs to working the best he ever has! Could not recommend the products enough - they have been a life saver and we will never look back!

I have used the premier calm on my 4/5yr old Welsh d mare for a few months whilst I've been backing her. It just takes the edge of her esp as being a Welsh she can be sharp at times..

The calming cookies were an absolute lifesaver when I had trouble loading my mare to move yards earlier this year! Have now bought some just for emergencies and they arrived quickly, with human sweeties thrown in too! Definitely recommend
