My step mother had a poodle that did not like to be groomed, dang mutt bit her right thru the septum of her nose. It was a really painful bite that required a trip to the emergency room. Nasty little chit would get under my grandmothers bed when she would try to get him to go out. Grandma cured him of that, she had a yardstick that had brass tips on the ends and she would rap him in the jewels. Only took a few of grandma's encouragements to get him to cooperate, the dog would see her coming with the yardstick and he'd head for the door pronto.
