Heyrex Found My Dog

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.

Awesome Product and Amazing After Sales Support

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.

Keeping tabs with Heyrex!

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 is a GameChanger

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.

Our Paws-itively Essential Gadget!

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!

FAQs

What does Heyrex monitor?

Heyrex measures activity levels, mobility, scratching, temperature, resting patterns and sleep disturbances. This information helps to identify a range of behavioural and health issues – from fleas and allergies, to lameness or separation anxiety.

Heyrex provides 24/7 monitoring, and will notify you if there’s an important change. So you’ll always know how your dog is doing, whether you’re with them or not.

How does Heyrex show me this information?

Log into the Heyrex app on your smartphone or any device.

Heyrex2 analyzes real-time data from the monitor and presents it in a simple, easy-to-understand format, so you can track changes as they happen.

How is Heyrex different to other dog tracking products?

There are two big differences – that’s what makes Heyrex so exciting!

Firstly, it’s the first device in the world to combine health and fitness monitoring with a GPS “find my pet” locator. (Giving you way more bark for your buck).

Secondly, Heyrex was designed by veterinarians to provide high-quality health data for dogs. Heyrex delivers high-quality health insights using advanced AI and algorithms, making complex data easy to understand and use.

What are Wago points?

Just by using your Heyrex, you can earn freebies and exclusive discounts. You and your dog will get rewarded with Wago points when you hit your health and well-being milestones! 

You’ll be able to redeem your Wago points on things like dog foods, pet insurance and more.

Has Heyrex been tried and tested?

Heyrex has been tested for several years and trusted in global veterinary projects, including:

  • A presentation at the World Small Animal Veterinary Association Conference (2011).
  • Monitoring post-op recovery, skin treatments, and behavior in the USA, Australia, and New Zealand.
  • Specialist canine research at Massey University Veterinary Teaching Hospital (NZ) and Waltham Petcare Science Institute (UK).

Heyrex2 has been tested ‘in the field’ by dozens of pet-parents in New Zealand.

How does the connectivity work?

It’s a mix of wifi (for the health monitoring) and satellite (for the GPS locator).

If your dog is in an area without cellular coverage, the Heyrex collar device will continue to monitor your dog’s activity, and the data will update once they come within range again.

Is Heyrex easy to use? And is there support available?

Yes, and yes! 

Your purchase includes a QuickStart Guide to using your Heyrex.

You’ll find it easy to use. But if you ever have a question, or need help, the team at Heyrex are always available. Just drop us an email to info@heyrex.com.
