My Astrid's closer to deer-headed than apple-headed, and my parents little boy Dennis is very much an apple-headed...
Another point about deer-heads is that their eyes seem to 'protrude' slightly more (obviously not in a pug-like way

) This is a bit more visible from the front, so will show you from the front, as Deedlit's provided our side-model
Think my signature picture best shows Astrid's deerhead...
And here's Dennis.... (when he was younger - he's lost his black mask now...

)
