"Heyrex alerted me to Fred’s scratching while he was on a farm trip - turns out he had fleas!"

"Heyrex has been great for tracking Moose’s activity and rest cycles over time. The graphs clearly show his daily patterns and the big spikes when he plays with his mates."

Customer Reviews
We live on a large densely forested property. My cattledog Kandi has never seriously disappeared until last week. I was frantic until after 30 minutes of three of us searching, I finally remembered the Heyrex has Find My Pet on the Heyrex App. You can even change the location mode to update rapidly to find your pet. I clicked on it with shaking hands and saw she was almost a kilometre away. We all raced to her location and there she was. She was as happy to see us as we were to see her. The app showed she had crossed a busy road twice. Heyrex saved my darling dog. It has so many stats on sleeping, scratching, running and walking and more. It's wonderful.
I purchased a HeyRex just over a year ago for my new puppy who was a bit of an escape artist. It gave me peace of mind while I was at work of where she was and when she escaped and was picked up by animal control I was able to track her down within 15 minutes by increasing the ping frequency. It was also awesome to see how active she was and the notifications if she hasn't been active enough and needs a walk. Twice now, my pup has broken the device and once I'd let HeyRex know I have received a replacement the following day.
We’ve been using the Heyrex device for the past three weeks and it’s been a great addition to our routine. It’s helped us better understand our dogs activity levels, rest patterns, and overall wellbeing. The insights have been interesting and easy to follow, and it’s reassuring to see his trends over time. It’s especially helpful for noticing any changes that might not be obvious day-to-day. Definitely recommend Heyrex to any dog owner wanting a clearer picture of their pup’s health and wellbeing! How amazing is it to have a device like this made in NZ for NZ dogs! 🐾
Heyrex has given me real peace of mind as a dog parent. From tracking Tequila’s sleep and activity to getting instant alerts when something’s off, it helps me understand what she can’t say. Reliable, waterproof, and still going strong after 10 days. This device is now part of how I care for her every day.
Woof! Kronk and Yzma here! The Heyrex 2 is our new favourite thing. It gives our humans all the deets on our naps and zoomies, helping them understand us better.
Best part? We can run wild and free without our humans worrying about losing us! It keeps us safe, even when we're chasing birds out of sight.
And bonus: it gets our humans off the couch for more walks and runs! More fun for the whole pack!
Seriously, if you're a dog (or a human who loves one!), you need the Heyrex 2. Paws-down highly recommended by us!
