Today, GPS is ubiquitous, it’s affordable, and GPS location trackers are smaller than ever before. Dog collars with implanted GPS trackers are affordable, widely available, and well worth the investment. They’re quite similar to the GPS trackers used to track wildlife migration, and they can help you find your lost pet’s exact location in a matter of minutes.

The Astro offers a variety of GPS collars intended for hunting dogs. They combine GPS
with portable invisible boundaries, training features, and capability for tracking up to 10 dogs. This setup is designed for Bird Hunting Dogs. Not so much for the Urban Pets. Like many of these comments, I too have Whistle. I bought Tagg when first out. It was great and precise. They were constantly updating the technology to their website and support was great! At one time, after warrantee had expired, one of the collar transmitters wings were chewed off. Tagg replaced unit FREE OF CHARGE! The day Whistle acquired Tagg, all went to hell. The site did not track daily activity like Tagg did. Receiving notification your pet is outside the safe zone is a minimum 10 minutes until you get the notice and likewise when returned to safe zone. The “real time” tracking sucks, pet may be out of safe zone for 30 minutes and will show only one position on map. Tagg would actually track pets travel. False notices, like middle of night when dogs sleeping in my room not wearing transmitters…Go figure! As for customer service, Tagg was top notch…Whistle sucks! Have tried contacting them several times via Whistle site never getting a response. Currently have one of my two just stopped working. Looking for replacement for two better made GPS units that comes with good customer service> Any suggestions?
