Oscar isn't afraid of much, but after today's obedience class, he's not so sure about having big dogs behind him. One goosed him, and another barked and snapped at him from behind! We were working on the heel command, and poor little Oscar was just minding his own business and cruising along when it happened. For the most of the rest of the class he kept looking over his shoulder, but seemed to have recovered by the end of it.
