This... is Gunther. <3
He is a Black/Tan European Doberman from Germany (and can only speak German) and is known for being the Best of Show at almost ALL the dogs shows he competes in.

He first appears in the Dog AU of Teufort Times.
I never fully developed this episode, but the gang ends up at a dog show and I believe they hide in there so whoever's after them this time will have a harder time finding them with all the dogs going around. Pretty clever idea, if I say so myself. Of course I'd say that, I thought of it. =P

Gunther is in town at the moment for said dog show and...
Let's just say... Di REALLY likes the way he looks.
Ben gets rightfully jealous.

But, in Di's defense, it's her dog instincts and not hers herself.

Di's face is the representation of every girl that sees Gunther and Ben is the representation of every guy. XD
