New app helps dog owners find, track walkers

A new app offers dog owners peace of mind when leaving their pets with other people.
The app, called Wag!, allows owners to find dog walkers and uses GPS technology to track them on their trips. At the end of the walk, customers get a report card.
Dog owner Diana Liu says the app has given her a great new experience with walkers caring for her dog, Sammy.
"I had one dog walker, she said that she had walked Sammy but she didn't, so that was not a great experience. It just eases my mind a little bit more, I know the walk is actually happening," says Liu.
