Purchased two when we got our Jack Russell Terrier. Rarely used this one maybe 2-3x. It’s like new and already assembled! Features & details: 24” x 18” x 20” (LxWxH) Dog crate - foldable with double-door design for convenient front and/or side entry. Two slide-bolt latches on each door for increased safety and security. Sturdy metal construction; folds flat for easy storage/portability. Designed with mini dividers (1.04 cm between each bar) on bottom perimeter to prevent paws from slipping through. Optional divider panel and removable composite plastic pan included. Measure your dog from the tip of their nose to base of their tail while they are standing. Also measure your dog from the top of their head to the floor while they are sitting or standing. Add 4 inches to those measurments to determine the maximum height and length for the crate.
