When used properly, a dog crate mimics your dog's desire to find a safe and secure den and it should feel like a safe place for your dog. Ovation Dog Crates are wire models and they allow your dog a great view out and provide good airflow through the crate vs. the stifling plastic walls of many other crate styles. The sliding door dog crate design allows you to leave the crate open. Your dog can come and go as she pleases when you are around the house. Just slide the door back into place when you need to keep him contained. Ovation Dog Crates features a free divider panel. The divider panel hooks over the vertical bars on the sides of the crate and allows you to adjust the size of the crate as your dog grows. Ovation Dog Crates are also heavier than the crates you often find making this sliding door crate a versatile, long-lasting product for you and your dog!
