Who's Collie

I have no idea who's dog this is, I was crouched down on all fours in Gosforth Park trying to photograph Snowdrops and this dog sneaked up on me, dropped the ball and wouldn't bugger off until I threw the ball, I ended up doing this about half a dozen times.

I gave up on the Snowdrops until another day !

I'm off to work on the bike.

The bigger version is better.
