How Could Calm-K9 Help Your Dog?

The "Basic" Answer

There’s an important interaction between a dog’s GUT HEALTH and their BRAIN HEALTH.

How the brain feels, can be improved by what’s in the gut!

When a dog’s Brain and gut health are on point, they’re calmer, they focus on training better and guess what… THEY BARK LESS!

CALM-K9 was formulated by a vet and team of nutritionists as a convenient and natural way to boost your dog’s brain and gut wellness.

The "Sciency" Answer

There are three aspects that can affect barking:




We tend to place more emphasis on TRAINING so the other two may surprise you!

Believe it or not, brain and gut wellness have a huge impact. And it’s the interaction between the brain and gut that is particularly significant!


There are two key ‘neurotransmitters,’ in the brain that are important:

GABA, a neurotransmitter which provides a calming effect on the brain and body.

SEROTONIN, which helps to stabilise moods, regulate anxiety, control sleep and regulate feelings of well-being and happiness.


Good bacteria in the gut impact neurotransmitter creation and even directly signal the brain itself.What’s in our dog’s gut can directly affect how the brain feels! (That’s why so many dogs have been transformed through feeding the CALM-K9 supplement!)

You can see how with this delicate interconnected relationship, if our dog's gut health isn’t on point then that affects the brain, and if our dog’s brain isn’t in a good place then this can directly result in more BARKING!

AND… we can see even with the best training in the world, if brain and gut health aren’t in harmony then the our dogs are less likely to respond well and give us the outcome we’re hoping for… Less barking!







If your dog is on behaviour medications, epilepsy medications or other drugs that act on your dog's brain, consult your veterinarian before starting CALM-K9 use.
