The character design of Derek was just one of many ‘odd dogs’ I sketched, not sure why, just followed my pencil as a I drew over 100 of them. As you can see they came in all shapes and sizes.
I think it became an exercise in pushing shapes in slightly recognisable ways, looking for unique ‘characters’.
And one of these characters happened to be Derek. He’s at the bottom right of the sketches below. Big nose, ‘tin tin’ hairline, floppy ears.
He eventually morphed into a more ‘adult’ dog character. More of a ‘runner’ type dog. But still with a large appetite, and belly to match.
