No, we don't cover our furniture, and they also are not allowed on it either (but as of now, they don't care-I've tried to get them to lay in the chair with me or on the bed, but no way!).
But mind you, just because they don't get on the furniture by no means, means they haven't put their hair all over it:rolleyes:
In my house dog hair is garnish, it goes with & on everything:p
