We needed something other than the traditional metal dog crate to contain our puppy. We have a very “senior” dog, also, that just can’t take the constant playfulness of the youngster.  Since we use the traditional crate at night, we felt badly putting him in there during the day when our older dog needed a break.  Then we found this item which has been a game changer. It’s large enough for him to still “play” around In with his toys. He doesn’t feel confined and it’s very easy to  
move around from room to room. We highly recommend  this item.
