Calm-K9 - Multibuy - 3 Pouches

CALM-K9 is a natural calming dog supplement that has been specifically formulated by vet, behaviourist, trainers and a team of nutritionists to provide support to your dog’s training and behaviour transformation whilst helping them in times of need.

When given daily, CALM-K9 provides ongoing support for life’s unexpected and sometimes stressful events such as fireworks and new situations and the common ones like meeting other dogs on a walk or being left home alone.

This calming supplement specifically targets your dog’s brain and gut health with proven results to improve reactivity struggles such as barking, lunging and lack of focus.

With so many calm dog supplements on the market, why choose CALM-K9? 

Our carefully researched and high quality natural ingredients have worked to transform thousands of dogs and improve their quality of life. Our key Ingredients include:

  • Mood-boosting Tryptophan proven to relax and calm
  • Gut supporting and soothing probiotic L-glutamic Acid
  • Calming Passiflora and Lemon Balm

We know that your dog’s brain and gut health impact on their behaviour and these key ingredients are what makes this calming dog supplement so effective.

How quickly will CALM-K9 work? 

CALM-K9 is usually rapid acting and some changes can be seen straight away. But just like humans, all dogs are different and others may see improvements after 50 days.

⭐️⭐️⭐️⭐️⭐️"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

⭐️⭐️⭐️⭐️⭐️ "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

⭐️⭐️⭐️⭐️⭐️ “As the owner of a very excitable spaniel my dog trainer recommended this product and after just a few weeks everyone in the family says they notice such a difference in her. It just takes the edge off her excitement and makes her easier to control. Would highly recommend.” - Patricia J

⭐️⭐️⭐️⭐️⭐️ “Life-changing! Due to traumatic experiencesMy GSD was dangerously reactive. Calm k9 calmed her enough to respond to intensive training and behavioural work. Result…….a happy relaxed dog I enjoy owning” - Susan E

Can't believe what a difference we can see already, combined with playing sexier than a squirrel games we now have a very relaxed dog!

It’s not made any difference yet but it’s only one week.



Hi Michael, Thanks for your feedback. As with all supplements, some dogs will respond well to it whilst others won't respond at all and I am sorry to hear that you haven't seen any of the benefits of the Calm K9. As the supplement is made from a mix of slow and fast acting ingredients, so it can take up to 50 days for some dogs to show the results. Hope this helps
