Hi. I'm a dog walker. My business is Hike Pups Dog Walking. This is my client, and when we walk, he usually poops three times during our walk. This time he has actually gone 4 times. I want to show you the device I use called The Fifth Paw. He is the most adorable dog on the planet. We are also working on some training, so the best thing about The Fifth Paw is that it gives me hands-free! I don't have to carry the poop bag or carry or pack it in anything I am carrying. As you can see there is four poop-bags on here (2 green and 2 black) They stay on really well, and we walk pretty fast most of the time, so it's a great, great device. I highly recommend The Fifth Paw to hold your poop bags.
