For a small dog, compare the complete weight and dimensions of tracker, mount and collar or harness. Follow the maker’s suitability guidance for the exact model. A longer advertised battery life may come with a larger device that is less comfortable on a small animal.

What to check
Check that the mount stays secure without restricting movement or causing rubbing. Introduce the device gradually and inspect the attachment after walks. If the dog has particular health or mobility needs, ask a veterinarian about suitability rather than relying on a generic weight rule.
Before you rely on it
Once fit is established, compare live updates, coverage and charging. Compact devices still need a dependable service and battery routine. A small Bluetooth tag is not automatically equivalent to a connected pet tracker, especially on quiet paths without nearby compatible phones.
