This crate includes a plastic leak-proof pan that allows easy clean-up in the event of an accident. We recently enhanced the safety and security of the New World crate by adding locking tips on the slide-bolt latches to securely lock the door the and patented Paw Block, which prohibits your dog from tampering with the door lock from the inside. New World crates also feature patented rounded side clips that reduce possible sharp points to ensure a safe experience for you and your pet. Every New World metal dog crate conveniently folds down flat for travel. The 30" New World (model B30DD) measures 30L x 19W x 21H inches and is suitable for "medium" dog breeds. **Please note the term "medium” breed is subjective. For the best fit, we advise that you check the measurements of the dog crate and select a size that will be suitable for your dog's ADULT weight and measurements. Your dog should be able to comfortably sit upright, lay down, and easily turn around inside the crate. When in doubt, we suggest you purchase a larger crate option
