Hmm... Oh, I know!
Hands down, the Beauceron.

Look at that beautiful boy! However, what has really dubbed them a favorite of Vesp's is their mutation of the dew claws. That's right, most if not all beaucerons have two dew claws on their hind limbs. It reminds me of a raptor if nothing else.
Another favorite of mine is the Borzoi hound.

Vespian, as a character, is actually a borzoi mix in his mortal skin (when not a hideous beast). I love how elegant they are and how their rather long legs can give certain people a vibe of discomfort.
