This collapsible soft dog crate folds flat to 3.5-in and opens back into a 28-in x 21-in x 21-in den for medium dogs up to 35 lbs. Tear-proof 600D oxford cloth stretches over robust metal pipes with reinforced corners, so the walls stay square while a dog settles in. Three roll-up doors with self-locking dual zippers control how a dog gets in and out, and breathable mesh windows keep air moving and the view bright. A removable washable plush cushion lines the floor, two removable pockets hold a leash and supplies, and a side handle plus padded carry strap ease the trip to the car.
