Portable & Collapsible Dog Crate: Our dog crate is so much easier than other foldable fabric travel crates where you have to struggle to insert tension rods along the corners and tops of the crate. And also super easy to collapse by simply twisting the turn handles on the ends to unlock the tensioners. The included carrying bag makes it easy to store and transport the dog crate and takes up minimal space, making it easy to carry either in the trunk of the car or out of the car. Safety knob & Zipper & Leash: To ensure the safety of your beloved dog inside the crate, our knob is designed with a two-step locking mode. When folding, you need to gently pull it out before you can rotate it normally, to prevent the crate from suddenly folding. The safety leash inside our dog crate clips onto your dog's collar to ensure they stay safely inside it.
