Wondering why your mutt is gaining weight and your pet food bill is going through the roof – even though you’re regularly feeding the dog what you always have? Could it be that someone else in your household is feeding your pet, too, or forgetting to walk your canine pal. And when was the last time your dog had its flea or heart medication? A new, easy-to-use three-button device called the Dog-e-Minder should help solve some of these problems. It attaches to your pet’s collar and shows the last time your dog was fed, walked or had its medication. When idle, the Dog-e-Minder works as a backlit identification tag.
