Living in a Northern rural area, winters can be brutal. Often, the snow is deeper than my little dog is tall and it's almost impossible to walk him outside. I saw Doggie Lawn on FB and decided to give the grass a try, which worked almost immediately. Then, I learned of their Bark Potty and thought that might be easier, and it is! It's lightweight, easily set up and disposable. My dog took to it right away without any coaxing and he uses it faithfully. I am more than happy with this product and the work /mess it saves me!
