No to Shock Collars.
Yes to Real Behaviour Change.
Shock collars use pain to control behaviour. We don’t.
Backed by canine behavioural science.
The Calm K9 Pro™ emits a high-frequency sound (20–30 kHz) that humans can’t hear, but dogs can.
The sound is designed to interrupt unwanted behaviour like barking, aggression, or anxiety-driven reactions, giving your dog a moment to stop and refocus.
Helping your dog feel safe, supported, and calm. Because being a “good” should feel good.

Worked in secounds
I was honestly shocked how fast it worked. My dog barks at EVERYTHING. Neighbours, birds, leaves moving. Tried Calm K9 Pro, and he just stopped. House feels so much more peaceful now.

I tell all my clients to get one
I train anxious and reactive dogs, and I’ve tested everything. Shock collars are a hard no for me. Calm K9 Pro is my go-to—it gets their focus without stress or pain. Easy win.

Literal Magic
We’ve tried so many things, dog school, treats, distractions. First time we used this, our dog stopped and actually listened. Total game changer.
