Puppies grow fast! So we made a crate that grows with your puppy. Since the Expandable Pet Crate can expand as your pet grows, it saves your time and eliminates the need for a future crate. It has a lift and lock door on the side panel that gives you easy access to feeding dishes and training pads. The plastic Expandable Floor Tray protects your floor. Available in three colors; Dark Brown, Cherry Brown and Natural. Divider and Wire Top are designed exclusively for the Expandable Pet Crate to separate pet's living area and to provide additional security to your pet. Assembly required.
