As a wonderful crate alternative, the large pen provides a very generous space and is the perfect choice if you must leave your pet for longer workdays or if you have multiple pets. It can be set up in two different configurations, a rectangular two panel by three panel shape or a narrow rectangular one panel by four panel shape. The Large 27” Lucidium Dog Pen is an oversized, indoor enclosure, with 3 color choices and a drop-down bar at the door for walk-in access, and clear panels. All Lucidium pens are intended for small and medium breed dogs (up to 40 lbs.), puppies, and other small animals like rabbits, guinea pigs, kittens, and ferrets. They are not designed for large dog breeds or pets that are aggressively trying to escape.
