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.

Customer video review of Calm K9 Pro™

We have a superintelligent and defiant toy poodle Miss Pepper as well as an adorably loving but reactive guardian Toy Cavoodle Mr Darcy. Mr Darcy has the hearing of a supersonic radar and can hear movement (translated as threat) for Kilometres so as the world goes on he can be a bit (very) yappy :( Buy using this device with the tips of verbal praise, they have both settled in very well to observing the goings on in the world with out comment. This took no longer than 3 days with a maximum of 4 zaps on day 1 reducing each day. It is now week 2 and we have engaged the power of the button only a couple of times to remind them. I am so grateful for this tool and so very proud of our little fur babies.

Customer photo review of Calm K9 Pro™

In the small town we live in every 2nd house has a dog or two. The dogs are the alarm for the town letting everyone know someone or something is moving around. At times my little dog thinks he needs to bark continuously even when there is nothing or nobody around. I have only had to use the device once and he stops and returns to my side. Considering I have had it for a few weeks it has held charge really well. I have even leant it to my neighbour who walks every morning and afternoon without a dog to shut all the barkers up as she walks. Fantastic device and can 100 percent recommend it.

Milo’s very good now . It worked wonders

Customer photo review of Calm K9 Pro™

It's great, it calms my dogs down from upstairs if they are barking at a possum in the back yard. It's not as great if they are seeing someone come through the front door. But it definitely calms it more! Been recommending to family with protective dogs

Customer photo review of Calm K9 Pro™

It used to drive me crazy the extended barking at the gate. Within days judicial use and reward for responsiveness it is great. He is calmer in that he no longer winds himself up. It’s great being with him in the yard. Thank goodness that at my wits end trying to stop his behaviour I have finally got something that works.

Our puppy is a barker but this is a 🙌 blessing

Customer photo review of Calm K9 Pro™

I admit I was very sceptical when heard about this, but my friend was so adamant that it worked for her dogs so I ordered one. Well what a brilliant surprise! It works fantastically on my stubborn dachshunds, they are very loud barkers, and no amount of yelling would make them stop. Every little noise outside would set them off! I had tried a bark collar on the worst offender, but it was useless. This little gadget actually works, I used the first beep, but when they ignored it I used the sound wave, boy did they stop in their tracks and be quiet. I only have to show them the beeper now and they settle down straight away. Oh and by the way, it's very sturdy and well made, I am extremely happy, so glad I took a chance 😊

I inherited 2 dogs after my partner passed away. With my 2 dogs it gets very loud when someone comes calling. It seems to work well. Haven’t needed to use much as they now listen when I tell them to stop lol 😂

Works well for my younger dog but not so much for my old deaf dog. Scares my cats so have to use outside with doors shut.

This has saved me actual headaches! I’ve had the Calm K9 pro for a few weeks now and it works so well. My puppy is very reactive so when I don’t want her barking I just press the button for a couple of secs. It gets her attention, she stops, looks at me then I praise her and she comes for pats. Sometimes I just show it to her and that’s enough.

Customer photo review of Calm K9 Pro™

We live next door to a dog that barks ALL THE TIME and it turned our 2 into barkers as well. We've tried the collars that vibrate when the dog barks and while they worked when worn, the barking was just as bad when not worn. We followed the instructions - using the beep as a precursor to the sonic button - and it worked immediately. They've pretty much stopped barking at things they have no business barking at, but we let them alert us if people come to the door. We also treat them everytime they self manage their barking - so they absolutely understand how this works best for all concerned! AND... the neighbour is SO IMPRESSED she's asked us to buy her one for a Christmas present, which we have. So, come Christmas morning our street is going to be a LOT quieter and peaceful!

My little tiboodle has been a dream to train with Calm K9. I couldn’t believe how quickly she stopped barking. I bought 2-gave one to my daughter. She has 2 dogs, the groodle is easy peasy however ; the frenchie is another story ! She’s a toughy and when in barking mode, she won’t listen to anyone. She froths at the mouth, her heckles go up and my ohh my… she’s a killing machine 🤭 The funny thing is, she is the sweetest and placid dog you will ever meet ! Not sure how to manage that one. A real problem with other dogs passing by. She’s very territorial.

Maxwell has a problem with the dog next door, whilst treat reward sometimes works to stop the barking and bring him inside, it often doesn't. It took a few weeks, but now Calm K9 instantly gets the desired result - he comes straight in for his reward. I'm delighted.

Customer photo review of Calm K9 Pro™

Our dogs responded straight away, only used it one or twice, to stop there unacceptable barking, now we just point to them and say no barking or just use the beep button to remind them and they are behaving again, as they definitely don't like us using it again.

Calm K9 Pro™

Customer photo review of Calm K9 Pro™

My dog would bark endlessly at people walking past. She would also jump and bark against the fence an torment our neighbours dog. It only took a few beeps followed by a sonic press to stop her reaction. Then only a beep was needed. Now she is quiet and settled getting far more pats and attention than ever before. If she happens to get hyper, I only need to show her the k9 calm now and she will settle down immediately. I occasionally stick my hand over the fence if the neighbours dog gets hyper and give it a press. She settles down straight away. It also works on my sister's dog when he visits. Now ..."I HAVE THE POWER"...😁

After it taking long time to arrive I was hoping it would work on my scruffy mob I am happy to say it does every time someone drove up our drive they would all bark And run madly to the door Well after a couple of times using it I only mainly have to have in my have and say no barking and it works 95 % of the time so I am very pleased with my calm k9

I was sceptical to be honest as I had tried so many different ways to stop my boy from barking. I can verify it actually works! The great part is I don’t have to often use the sound as he’s deterred once he sees me with it.

Customer photo review of Calm K9 Pro™

We have only had the calmK9 device a few days and already my dog’s barking is much less. He sometimes still barks out of habit and then stops abruptly as if he just remembered if he keeps barking there will be ‘the noise’ he doesn’t like. We are very impressed It’s the first thing we have used that helps.

The change in my two dachshunds was instantaneous. Once they learned that barking was not an acceptable social activity, the neighborhood embraced the peaceful quiet times.

We have a Rescue Irish Wolfhound cross who in the last 12 months has found his voice. Up until now we have had no control over the very loud bark, that would go every time someone came near our front door, or our poor neighbors just coming out of their front door. Well so far we have only had to use our Calm K9 Pro a couple of times. He now only needs to see it to stop, I am so grateful We finally have control of him. And the absolute best customer service. Thank You Calm K9

Good quality product is as advertised, great way to reduce annoying barking, also has a led torch. Good for night walks.

Yep had to wait a while for delivery but finally turned up works better than what I expected

Calm K9 Pro™

So far only used it once 😆 lol

Calm K9 Pro™

Worked immediately Great product

Calm K9 Pro™

It worked for two days then it stopped. I have many dogs of different ages and they feed off each other , so in a pack situation it doesn’t work sadly

Calm K9 Pro™

We found that it definitely works indoors and now all I have to do is hold the device and she stops barking. Not as effective outdoors for our girl.

Calm K9 Pro™

Unfortunately, it does not seem to work on my Jug who just loves to bark at delivery drivers and the postie.

Calm K9 Pro™

Hasn’t made a difference for my Border Collie at all. Have mixed up the frequencies to add variation and still no luck unfortunately. Very disappointed in product, especially for the cost of it.
