Get email when your dog leaves the yard
Attach the collar to your dog. Define the area you think your dog should stay in (i.e., the backyard, Chase!) When your dog leaves that area, you’ll get an email that says he’s left AND the location where your dog is at the moment. If this is going to work for Chase, it better send an update every thirty seconds.
The device is supposed to be out by the end of the year and will cost $300 plus a $13 monthly fee. As to what this means if applied to children is a topic I will leave for another time.
