A fisherman in the Gulf of Mexico was shocked when a dog appeared beside his kayak, far from shore. In this video, you can see him pull the Vizsla to safety [3] and comfort the shivering canine. At first, he thought the dog was cold but after seeing bleeding cuts, he realized the dog was traumatized.

The mystery was solved when the kayaker heard on the news that a woman, Donna Chen, had been struck and killed by a drunk driver while walking her dog Barney [4]. Barney had no tags on his collar. But when the kayaker brought him to the vet, he was scanned for a microchip. It was this microchip that allowed Barney to be reunited with members of Chen's family.

Does your dog wear tags at all time? What information is on yours? What about a microchip?
