The Lab's Verdict

Best wireless fence collar

Halo Collar 4

A GPS collar and a wireless fence in one. You draw boundaries in the app and the collar keeps your dog inside them, anywhere, no buried wire. Premium price and a subscription, but uniquely capable.

Alternatives to consider

Best overall smart collar

Lab Score

Fi Series 3

The smart collar that nails the basics other brands fumble: weeks of battery, escape alerts, and serious activity tracking in a rugged, good-looking band. The default pick for active dogs.

Best for training

Lab Score

SportDOG

SportDOG 425X

Not a tracker, a trainer. A rugged, waterproof remote training collar with fine static, tone, and vibration control out to 500 yards. The pick for recall and field work, used humanely.
