Now this is a absolute must have, we recommend at least one of these, if not two. They hold up well and take up little space. We can set up a safe play area in our yard, or camping or traveling, in seconds and easily able to move it around the yard saving our lawn for being destroyed . We also use them indoors with a piece of linoleum under it to make a puppy training area or very large kennel area. This along with a dog litter box and a bag of wood pellets this system will work well if you must leave your puppy alone for any period of time (we use the same pellets used in our wood pellet stove) . By the time you pick up your puppy at 8 weeks they will be using the litter box regularly and be 95% trained to use this system.
