I bought these to potty train my new puppy. They worked great until my puppy realized that they make a better chee toy than a bathroom. I would come home to these shredded all over the house and pee on the ground. Although these sound like a great idea its much easier to crate train or buy a bathroom area that cannot be torn up by a bored puppy. This may not happen with all dogs but it has happend with both my dogs when they were puppies.
