Dog turns playpen sideways like hamster wheel

I was trying to clean up so I had to lock my puppy up for a while, and well this happened. Cuando encierras a tu angelito Para poder trapear (When you lock up your little angel So you can mop). Woman puts her puppy inside its play pen so she could mop and clean the floors, but her puppy found a way to walk around by turning the play pen sideways and roll it like a hamster wheel
