What is the Difference Between the Halo 3 and the Halo Collar 4

The Halo Collar 4 is stronger, more powerful, and packed with new improvements designed to provide more reliable tracking, enhanced durability, and a better overall experience for both dogs and pet parents.

This helps ensure your collar stays powered longer while making charging more convenient.

This allows the collar to be custom-fit for both small and large dogs without needing multiple size options.
