**New Gluten-free formula, new packaging, same volume!**

Provide natural support to the brain and gut in a scoop-a-day!

Your dog’s brain and gut impact on their behaviour, which can limit training progress and seem like you aren't making any progress at all at times!


CALM-K9 has been specifically formulated by vet, behaviourist, trainers and a team of nutritionists to provide natural support to your training by helping to support your dog's brain and gut microbiome.

And to make sure your training is on the right track too - we send you a free training eBook with every pot!

By considering these pieces of the puzzle along with training, you can move closer to your dog's transformation potential!
What's your dream? Being CALMER? Less “REACTIVE”?
Or simply more able to have a relationship with you that you dream of and that made you get a dog in the first place?


⭐️⭐️⭐️⭐️⭐️ "Fantastic! - Within 2 days of giving my energetic 18 month old Irish Water Spaniels (2 brothers) their behavior changed. They listen and respond on the FIRST command! A few weeks later we now consistently have recall from our "wanderer" on the FIRST call. Our other, timid boy, is much less reactive to passer-bys and visitors at the door. Even our friends have noticed the change. I can't thank you enough!" - Linda J

CALM-K9 - An all-natural, non-sedative dietary supplement for dogs that bark, lunge or lack focus. 

    • 3-Step multi-targeted approach to dog behaviour transformation.
    • High-quality natural ingredients - Made with mood-boosting Tryptophan, a gut supporting probiotic, soothing L-glutamic Acid, and calming Passiflora and Lemon Balm.
    • Ongoing support - CALM-K9 can be given on an ongoing basis to support them through life's unexpected events and to support your training and lifelong relationship!
    •  Rapid Acting - Some changes seen straight away, others taking 50 days.
    •  Helps all dogs - Whatever the breed, age or size of your dog.
    • Works with any diet - just add one scoop per day.

⭐️⭐️⭐️⭐️⭐️"Being sceptical I held back from rating until I finished the first carton. My dog has improved no end in the six weeks. She is calmer, walks on a loose lead at my pace and her recall is virtually instantaneous. I have just ordered three more pots." - Terence May

I’m amazed at how well this has worked. I really wasn’t expecting such a significant change. My Romanian rescue was highly reactive to dogs and cars, as well as highly energetic/active around the home. She isn’t magically cured but she is so much more relaxed and significantly less reactive.

Combined with the games from AD, this supplement is helping Oscar to become more focused and responsive. Oscar is growing in confidence and becoming calmer each day. And all this after only using the supplement for just over 2 weeks!!!

Very good

Can’t believe the difference in our 2 year old cockapoo

Not delicious

Since taking this my dog is definitely more able to regulate his arousal levels. For example, he’ll let out a woof when someone knocks on the door but will be quiet after that whereas before we wouldn’t be able to get him to stop barking! However, getting the powder in him is a struggle as he hates the taste so if we sprinkle it on his food he simply won’t eat, hence the 4 stars.

I have only been able to test it for one month, I have not got the second one yet, have only paid for the second and the third.

  • There’s a lesson for that

    Karl achieved off-leash freedom!

    Owner, Lynn said “We are going through a unsettled time at the moment, we are moving and there are lots of different people in our house as well as cars, noises etc. it’s not easy but I would not like to think of how he would be without Calm-K9.”

  • There’s a lesson for that

    Mabel learned she didn’t need to get involved with every dog on her walk!

    Owner, Maria said “Such a big improvement already – I can tell that this is really going to facilitate her training and allow her to focus more! We will definitely be continuing”
