How do I stop my 6 month old chocolate lab from doing his business in his crate. We leave him in his crate from 7am-3pm while we are at work and school. Every day we come home to a messy dog. I've tried everything that I can think of to correct this problem by feeding in the crate, different toys each day, blankets, music and T.V. on, dividers, moving the crate from downstairs to upstairs.
