I'm not voting. That small photo is nearly half in shadow, on my monitor, and it's only a head shot. Not anywhere near enough of the animal is visible to see if there is any apparent wolf heritage. Not to mention characteristics can be hidden in appearance yet show up in movement and/or behaviour and we are not privy to ways to see that either. If the question had been Does this dog LOOK part wolf I would still say there is not enough to see to tell by.
Is this a trick question to see how many people will fall into snap judgements with little to go on? If so, good one.
