I read a lot of reviews on setting up the potty indoor dog program and it wasn't my top choice for puppy training. But, in January I got my Siberian husky puppy and it was a rough winter in Wisconsin and she didn't have the energy to do snow & ice walks. Which meant, I needed to develop an effective potty training strategy until we could turn to daily walks. I'm not comfortable having the odors associated with an indoor system; there's nothing worse than walking into your house and smelling animal waste instantly. I purchased this artificial grass and they worked perfectly as expected. It took me only a few hours to install it. My dog loves it!
