My dog Wizard may look like a wolf,
but underneath all the fur he's a wimp.

Now, I found this behaviour endearing. Wizard perceived it quite differently. In his mind, there's only one reason why something creeps up behind you. He's now convinced that all waterbucks are out to get him. Each time we meet one, he goes into 'drag' mode, lowering his head and tail and hauling me homeward as quickly as possible.
