Walk stats
Distance and duration from GPS plus step counting.

Dogs can’t tell you they had a rough night. The HALO chip can. It tracks total sleep, restless periods, night waking, and whether your dog is settling down or pacing.
Sleep time & quality
Total sleep and restless periods, night by night, against your dog’s own normal.
Night waking
Catches the 3 a.m. pacing you’d otherwise sleep through.
Senior dog changes
Flags a flipped sleep schedule or night-time restlessness, early signals of cognitive decline worth raising with your vet.
