My son just bought one of these for monitoring his 16 month old dog. It is essentially a "fit bit" for dogs and is completely interactive via your smart phone. I would recommend this for anyone who wants to take charge of their dog's activity and goals met. My son has had his now for just over a month and has both my wife and I on it as well as registered users. My son was in Barcelona last week and could follow his dog's progress as we were the dog sitters last week.
