Good idea. Nice web site.
The idea behind Take Your Bag for a Walk is more about creating lasting change than it is about the bags themselves. If you really want to cut down on your plastic bag use, you have to ADOPT THE HABIT of having your reusable bags with you all the time. Which is why you get 3 in a set — you can keep one in your car or bike basket, one in your purse, one by your front door so you remember it when you go out.
(Not being a dog fan, I suggest they have a robot line. But that's just me.)
