Weighing in at under an ounce, the Dog-E-Tag is a digital dog tag that lets you store a lot more information than those boring old analog versions. Especially if you're one of a growing number of people who travel with your pet, you want Spot to have as much emergency info as possible on that collar. You're no longer limited to a name and phone number, as the Dog-E-Tag can hold 40 lines of 10 characters each. Enter the dog's name, your name, your home address, your phone number, canine medical data, the dog's favorite foods, your online dating nickname, the dog's online dating nickname, whatever. The tag is water resistant, shockproof, good for cold or hot temperatures, and has a backlit display. And it comes in six different colors to match your pooch. The Dog-E-Tag sells for $39.95 plus shipping.
