I came home last night and my husband had a portable vacuum out to clean up something behind the bar. I absent-mindedly reached down and unplugged it. Later that night I heard Dakota chewing on, what I thought, was his bone. Shortly, he brought a piece of black rubbery and brassy material over to me. I walked over and looked at where he was chewing and he had chewed the cord of the vacuum in half. If it had of been plugged in, we would have lost him. Our pups are like babies, so be sure to baby-proof your houses. We sure learned our lesson--the easy way, thank goodness.
