There is actually a GPS watch that you can have your child wear . You can track your child online and it will show you a map and tell you within a few feet , the street address where you child is. I honeslty considered buying this watch for my 9 yr old daughter.It has two buttons. One button if pressed for 3 seconds, it contacts the police and she can be tracked. There is a monthly fee for this like $20 a month. The watch costs $180
There is also a GPS collar for dogs and it works the same way. If your dog runs off or is stolen ,you can immediately go online and get a map and street address of where your dog is. The only problem with the collar is that it is best for dogs that are bigger than most Yorkies
