I just saw a commercial for a weight loss system for dogs made by science diet. It had pre-portioned meals and special biscuits. My mouth just dropped open. Now I don't know if this works or not, but I can't believe people would spend money on that! I guess I don't understand why people just can't measure out the proper amount for your dog and do research on weightloss for dogs rather than spend a ton of money on a weightloss system. I know science diet's regular food is expensive...I can't even imagine how much this must be!
