This is how I crate train a puppy. This is a great tool to aid in house training your pup. The more times your pup will have success in waiting to go to the bathroom until you get them outside in the morning.... The faster they will figure it out. When you take your pup outside, always take them to the same place.. the smell will help them connect the dots. Note: this is also why accidents in the house should be cleaned up well, because AGAIN... the smell will tell them where to do their business.
You will move the divider every few days... to a bigger area as long as they are having success.
