backing up when confronted with something he doesn't like the look of, say a stupid little fiddly gate or going under or round something difficult, or when asked to stand still at a junction for example, is becoming a new habit
but he's quite old now and hasn't really done it before or at least hasn't got away with it - do I need to start beating him to push him forward? as it is I feel like a bully kicking an old man and growling at him
