5 reasons to choose Heyrex
Collapsible content

Help them live better, for longer
Heyrex tracks your dog’s activity, sleep, and stress, alerting you to health changes early. This helps prevent serious issues and keeps them healthier for longer.
Know when your dog is in pain or sick
Dogs hide pain, making it hard to know when something’s wrong. Heyrex tracks changes like more scratching, trouble moving, or a rise in temperature, helping you catch problems early. It’s like having an extra set of eyes on your dog’s health.
Track their location
Heyrex’s GPS and “Find My Pet” mode help you track your dog in real time
Lower vet bills
Catching health problems early means a quick vet visit instead of an expensive emergency. 1 in 3 vet emergencies can be prevented, and waiting too long can cost over $2,000. Heyrex tracks early signs, helping you act fast and save money. Your vet will also appreciate the accurate data.

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.
