The Green Interactive Pet Feeder is a way to feed your dog without having them inhale the food within 8.4 seconds and is designed to resemble grass. Just pour the food in between the green ridges of the feeder and it acts as a reward type system while they eat, plus it takes them a while to finish. Personally my dog will eat his meal, puke it up because he ate it too fast, then we need to feed him again, pretty much every other day, so this will definitely help people in a similar situation.
