Our Bower has many strange habits but his most recent obsession is cobwebs. We have to clean our walls weekly to keep the cobwebs and spiderwebs from appearing but if we haven't gotten them all-he lets us know. He will sit and bark at the cobweb until we remove, then he'll search for another until all the webs are gone. Then he rests peacefully in his crate and goes to sleep-he's a weirdo.
