My chili is not a barker, but he does bark on occasion if I put him in his crate when company comes over and on some occasions to get me out of bed in the AM. I used to put a sheet over his crate and that used to work, but not any more. the only thing that works is ignoring the barks(about 15-20minutes) and then he finally realizes to shhhh and takes a nap. so honestly I cant give you a solution, it would drive me nuts if chili was a barker more than what he does.
