Never Lose Your Pet

Tethr is a GPS Dog Tag with an amazing long lasting battery, so you'll never lose track of your four-legged friend again. 


Track Your Pet Everywhere

Tethr uses a global GPS system, cellular networks, and bluetooth technologies, to give the most coverage of any pet tracking device. Track your pet in over 100 countries.



Longest Lasting Battery

Tethr's patent-pending battery technology provides unprecedented battery life- up to one year on a single charge!  That is over 30x longer than similar devices that need to be charged every week.  On the rare occasion when your battery does need to be charged, you'll get a notification from the accompanying mobile app.


Designed Specifically for Pets, by Pet Owners

  • Attaches to all types of collars and harnesses
  • Durable anodized aluminum and rubber design
  • Waterproof up to 20ft
  • Custom engraving of name and contact number
  • Dimensions: 1.0" x 1.0" x 0.4"


Virtual Fence and Alerts

The free Tethr App includes the option to make a virtual fence.  You define an area on the map and Tethr will send you a push notification if your pet leaves that pre-defined area.  If you have a furry escape artist on your hands, you'll always be the first to know when they are on the run.


One for Every Style

We're working on creating a fun assortment of colors and materials.  We'd love your input.


The Ultimate Peace of Mind

Never out of range.  Never out of battery.  Tethr is always there for you when your pet isn't.
