The Wellness Supplement for Pet & Sports Dogs to Promote All-Round Wellbeing & Condition

Give your dogs diet and, in turn, your dog a seaweed-powered super BOOST! 


Wellness is all about supporting your dog as a whole - from their immune system, through to their brain and behaviour, organs, muscles, joints, skin and coat!


The world throws a lot at our dogs from pollution and toxins, infectious agents and general damage to the cells of their body - supporting the natural protection and healing systems in a world of less than natural assaults to their bodies is key!


Give your dogs diet and your dog a seaweed-powered super BOOST, with:

  • Superfood Sea KELP - the vitamin, mineral and anti-oxidant sea-derived powerhouse!
  • Nutrient-dense, vitamin and mineral-rich and antioxidant-packed SPIRULINA!
  • A unique blend of amino acids, vitamins and anti-oxidants in a tasty powder to add to your dogs food daily!
  • Vital Vitamin B12:  Vitamin B12 is an essential B vitamin crucial for gut wellness, brain wellness and red blood cell formation. 

How much does my dog need, and how do I give the powder?


The supplements are given once a day, sprinkled over your dog's normal food (kibble or raw!). Just use our handy reference below to find out how much to feed, depending on your dog's weight:

You take your supplements and make a smoothy every day, I like to think this can give the same micronutrients to your dog and help them keep healthier for longer so you can enjoy fun together.

Prime seems to have been the key missing ingredient to our GSD’s gut health! Finally having consistently healthy poos!!!! I’m soooo happy!

A-OK9 PRIME-K9 Review
  • 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”
