This was recommended from the breeder but the cage is not well made. My 6 month old golden doodle has bent and tore up the divider to the point it can't be used. Now she has pawed and loosened the top lock on the side door we have to rig it so she can't jostle it and squeeze out. I would rearrange the position to use the end door, but the "helpful" sliding tray does not have any tabs to keep from sliding out while dog is in the cage so one end must be placed against the wall to prevent the tray from sliding and the dog having an accident on the surface below the cage. Buy a different brand, different store!!
