Never lose your dog again
After a co-worker had a 5-day ordeal tracking down her dog, I thought there must be better ways of locating a lost dog in this day and age. She had signed up for the implanted license technology that allows a vet to scan the dog's shoulder and retrieve the rightful owner's information. However this technology does not work if the dog is not directed to a veterinarian or shelter. Some quick searches later, and I was very impressed to learn that Garmin and other companies have come out with GPS-based tools to tag your pet, and monitor their location if they fly the coop.
