The Dog-e-Minder is a 3 button backlit device that attaches to your pet’s collar. It has buttons for feeding, walking and medicine. Anytime your dog does one of these activities, you can press the button so the time will be recorded. It makes a great training aid or as a reminder for busy pet owners, multi-pet homes and pet-sitters/walkers. When idle, the Dog-e-Minder also acts as a dog identification tag, displaying important pet name and owner contact information. It is available in several colors and you get two for $19.95.
