Dogs are pack animals by nature. Developmentally and emotionally they need to be with you as much as possible. So keep your puppy or smaller dog contained but close with this crate featuring locking caster wheels. Doors on the side and on the top of the crate allow for immediate access to your pup—just reach down and grab him! When you’re ready to play or train, he’ll be right there! Crate can be used with Puppy Training Tray Pads. Great for separation anxiety! Color: Green/White.
