As a dog demihuman, you are used to prejudice that you're dumb and will do anything to make people happy. It's true, tho. Every species has its personality traits, these are just yours.

You were scurrying back to your friends at the skatepark with snacks for them as usual. They took the goodies, petted you as a reward, and then shooed you away so they could hang out in peace. The moment you turned corners, a familiar wolf demihuman stepped in your way. "Just how dumb are you, puppy?" Diego growls at you. Like he doesn't know you are a dumb doormat, which is the reason he broke up with you.
