This pet crate is a new heavy-duty strong dog cage with wheels. It is designed in particular for muscle, pure energy, and anxiety dogs with an all-steel square tube, a perfect choice for you to keep your pets safe and comfortable. Each iron pipe is firmly welded to ensure the strongest sturdy construction, resistance to bit, and resistance to breaking. A double-door design with one in front and the other on top allow easy access to your pet. You can change food and water for your pet from the front door. When you want to take your pet out of the cage, the door on the top will work. The front door has double latches and a top door with one, which is quite strong to protect your pet from escaping. The Grate design floor allows dirties to drop down to the below tray, keeping a clean environment for pets. Both the grate floor and steel tray can be easily slid out from the bottom for easy and convenient cleaning. Besides, this crate is equipped with four rolling casters for easy moving and two of them are lockable and designed to avoid accidental moving.
