What sort of size do you think that would be?

Small and low energy enough that tiny migratory birds can wear them for months. Externally worn of course (e.g. attached to the ear, for a wolf).

You could adjust the firmware of a wildlife tag to start transmitting location every 10 minutes when the animal leaves a geo-fence.

		Bird ones are easy because birds are high in the air, so there's nothing to block the signal. They are also not implanted in the birds, but are a relatively large "backpack" or leg tag.

size of chip? they're tiny. dog owners typically have the vet "chip" their pet as a puppy. full-grown dog doesn't need a bigger chip.

		Those chips need to be scanned from about 3cm away. If you want a locator tag, it needs to carry enough power to broadcast a signal a useful distance. Still, a microchip is handy if you're not sure if it's your tiger you found.

		Those chips cannot track a dog's location
