CaniGPS will allow you, in conjunction with the CaniGPS tracker, to geolocate your dog in real time. The range is infinite, as long as your dog is wearing his tracker and you have your phone, you will be able to find him.

Virtual fences will allow you to be automatically and immediately informed if your dog leaves a pre-established area (garden, house, etc.).
You can also save your activities such as your walks or canicross training and automatically synchronize them to your dog's Strava account.
