What’s Our Final Verdict?

Visit Halo Website

The Halo Collar GPS system is an impressive piece of technology. Its original version had mixed customer reviews with complaints about collars breaking, unreliable GPS location, false positive alerts, etc. But the company listened to their customers and made a variety of improvements to address these issues, launching Halo 2 in late 2021 and Halo 2+ in mid 2022. We’re keeping an eye on customer feedback with the new and improved collar.

If you’re not sure you want to fork out the hefty price for this collar, you may want to check out our reviews of the best wireless dog fences to see if there’s a better, more affordable fit for you, or see how Halo stacks up with SpotOn. We also have reviews of the best GPS dog collars and smart collars. However, keep in mind these collars don’t incorporate a wireless fencing feature, so they’re limited if you want an all-in-one system.
