Aid a healthy senior brain and tip-top brain function. There’s a scoop for that!


**Brand New Product**

Maintaining the brain function (including sense of taste, vision and hearing) of dogs over the age of 7 is crucial so that they can continue to lead the quality and activity level of life they are used to.

You may note changes in your senior dog associated with cognitive decline:


    • Reduced energy or alertness
    • Disorientation, confusion or forgetfulness
    • Increased anxiety
    • Disinterest

If your dog is 8 or older, supporting your senior dog starts now.

That’s why our team of vets and nutritionists developed Calm-K9 Senior Boost. In a scoop-a-day, Calm-K9 Senior Boost harnesses the power of….


  • All the multi-targeted benefits of Calm-K9
  • Lemon Balm to promote senior cognitive function: Lemon Balm’s strong performance in Alzheimer’s and cognitive decline studies make lemon balm an exciting addition for senior dogs slowing down!
  • Microbiome-boosting probiotics for extra senior dog gut support
  • B vitamins for brain and nerve support
  • Lutein, vitamin C and vitamin E to promote vision and hearing: A 2016 study (Wang et. al) showed supplementing your dog’s diet with Lutein would be beneficial and effective in the long-term preservation and improvement of eyesight
  • K9 Brain Protection Blend: A 2018 study showed long-term supplementation with a Brain Protection Blend (made up of anti-oxidants and B vitamins) to have cognition-improving effects and supported the use of nutritional strategies for promoting brain wellness in dogs over the age of 7!

Since using Calm-K9 Senior Boost my 7 year old dog, Biscuit, has been much calmer and less reactive. Walks are actually becoming enjoyable again and it's so lovely to see him happier and more confident on a daily basis. I 100% recommend all of the A-OK9 products, they are simply fantastic! ❤️

Excellent Produce

I have already given a review. So I hope this one takes. I have four rescue dogs and two are reactive in different ways. One is the young one in the group, his is 7, two others are 11, and the fourth is 10 years of age. I am almost done with the first Senior Calm-K9 and it is working well, the dogs seem calmer, even though the 7 year old still wants to be played with especially when I am sitting down relaxing and reading the paper. The others go to the bed and lay down especially after breakfast. My reactive dog is still reactive when on a walk. So my thought that this would help hasn’t, totally, come true.

My dogs seem to have less digestive issues since they have been on the calm. My rescue whose fur was poor now has a shiny coat. Also without ot I noticed a huge difference in his behavior. He is more focused and able to calm faster than when he is not taking it.

  • 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”
