Free 60-second reactivity check
Does your dog lunge on the lead, react before you have even seen the trigger, or stay wired for hours after? It could be a broken gut-brain signal —and there is now a natural way to rebuild it.
Every day more owners find out that the lunging, the barking and the hours it takes him to come down — the things they blamed on "temperament" — actually trace back to the gut. Take the free 60-second check to see your dog's recommended daily protocol.
90-day money-back guarantee, even after the jar is opened.
Why gut health is the root of lunging, barking & hair-trigger reactions
Every dog has a line. Below it he can think, take food and hear a cue. Above it none of that runs — the learning centres are offline and the body is already moving.
Where that line sits is largely a serotonin variable, and over 95% of your dog's serotonin is produced in the lining of the gut, not in the brain. The vagus nerve carries it upstairs. It is a physical supply line, and the lining it runs from is a single cell thick. When the microbiome behind that lining is disrupted, the supply drops — and the line drops with it. He goes over sooner and takes longer to come back down. Training teaches him what to do below the line. Sedatives blunt what happens above it. Neither one raises the line.
What are the warning signs of a dog living above his line?
Here are the signals owners most often miss. Any two together are worth a closer look:
- Lunging or barking at dogs, bikes or people on the lead
- Reacting before he has even seen the trigger
- Staying wired for hours after a two-minute incident
- Perfect at home, impossible on the street
- Refusing high-value food outside, but eating anything indoors
- Pacing or panting in the evening, never fully settling
- Waking the house at 2 to 3AM
- Loose stool, gas or grass-eating on the same days he is worst
Get to the root of it — with a gut-first calming chew
CalmAxis™ Chews are a postbiotic chew. Not a sedative, and not another probiotic gamble that has to survive the stomach and colonise before anything happens. A postbiotic delivers the finished compounds a healthy microbiome would have produced itself, so the gut lining gets the raw material for that calming signal from the first chew.
Two chews a day, straight onto food, any size dog — 500 mg postbiotic metabolite blend with L-Theanine, Sensoril® Ashwagandha and chamomile. What owners describe is not a quieter dog. It is the same dog with a longer fuse: he still sees the other dog, he still tells you about it, but he comes back down in a minute instead of dragging you home wired. No sedation, no zombie-dog.
94% of owners on the daily chew reported a dog that settled faster after triggers within 7 to 21 days

Vet-reviewed & recommended
"The dogs I see for reactivity are rarely badly behaved dogs. They are dogs whose nervous systems have nothing left to regulate with, and a standard blood panel will not show you that.
I recommend CalmAxis to owners whose dogs go over threshold on every walk. The ingredients are natural and safe for daily use — no sedation, no side effects."
"Start with the gut before you decide it is temperament. In most of these dogs, that is where the story actually begins.
It is the kind of supplement I trust enough to give my own dogs — and one I happily recommend to my patients."
Loved by pet parents…
He looked, then kept walking
Week three, a spaniel came round the corner off-lead. He locked on. Then he just carried on. I stood there in the middle of the path like an idiot.

Still barks — but he comes back down
He still goes off at the mail carrier. That part I'd given up on. The difference is he's finished with it in a minute instead of pacing the hallway for two hours.
— Daniel
Two trainers and a prescription later
This is the thing that held. And her stool sorted itself out in the same week, which I wasn't even expecting.
— Priya
We walk at normal hours now
Six months of 6AM walks so we would not meet anyone. Last Saturday we did the park at eleven on a Saturday. He is not perfect. He is possible.
— Tom
…and thousands of calmer dogs worldwide!

How much does your dog weigh?
Is your dog showing signs of a lowered threshold — lunging, barking, reacting before you do, or taking hours to come down?
Building your dog's protocol…
Both answers take you to your dog's recommended protocol. 90-day money-back guarantee, even after the jar is opened.
Threshold refers to the point at which a dog stops responding to cues and training input. Individual results vary.
Serotonin is produced almost entirely outside the brain, in the enterochromaffin cells of the gut lining, and signals to the brain along the vagus nerve.
