## What reviewers say

**Tractive GPS DOG 6** — One whitelisted tester, Reviewed (USA Today), covers the exact 6th-gen Tractive (sold as DOG 6), naming it Best Overall in an April 2025 editorial roundup. It praises superior tracking across multiple cell-service providers, reasonable subscription fees, waterproofing, and 6th-gen additions (improved battery, brighter nighttime LEDs, bark monitoring), while flagging bulk and occasional app lag. No whitelisted outlet published its own hands-on measurements of this generation; Reviewed's accuracy claims are aggregated from other publications rather than its own lab test. (1 sourced review.)
