You could have knocked me down with a feather : Az is normally very cautious around strangers, particularly men carrying sticks. Normally if he's feeling really friendly he might sniff their hand and let them just touch his ears.
The chap was visibly moved by this. When I said how surprised I was, he said 'he must have sensed my loss, I lost my old greyhound lurcher last week'.
Chap was certainly a lurcher magnet.
