Every year the fourth graders have a learning/science fair. We have to invent something to. I invented Bling My pooch! It's a flashy, stylish collar, with a cool fashionable light hung on it. It's made for dogs that cant resist running out when you open the door. If you cant see your dog at night you need this! Made for boys and girls. I use this for my dog too. He will run out the house and across the street.
