Frequently Asked Questions About Kennel Doors

What is a guillotine kennel door? A guillotine-style kennel door slides vertically up and down — like a guillotine — rather than swinging open. This design is preferred in professional kennels because it operates cleanly within a narrow space, is difficult for dogs to manipulate, and creates a tighter seal than swing doors.

What size kennel door do I need? Our kennel doors are available in multiple sizes. As a general rule, your dog should be able to pass through with 2" of clearance on each side and 2" above the withers (shoulder height). Still unsure? Contact us — our team provides complimentary sizing help.

Do you offer chew-proof kennel doors? Absolutely. The Kennel Clad Swing Kennel Door (Chew Proof) and optional bite guard add-ons on our guillotine models are specifically designed to withstand even the most determined chewers.
