The large-breed palace and the biggest model in our lineup, it's a full 54" long to comfortably give the biggest dogs room to move. Each of our crates feature a unique, patio-style door up front that slides from side-to-side instead of swinging out and requiring extra-space to operate. A second, traditional hinged door lives on the side. All models also feature our butter-smooth double-panel sliding doors and rails for reliable, virtually silent access. We've engineered this crate with all sizes and dog breeds in mind. The 54'' crate can accommodate even larger breeds such as Great Dane, Mastiff, Saint Bernard, Great Pyrenees, Greyhound, Bernese Mountain, Irish Wolfhound, Leonberger and more.
