My Little Pony: Friendship is Magic - Image #662,391

Human Rainbow Dash.
It'd be quite fun and I wouldn't have to put up with a horse flying around my house.

Neither, because:

-I don't like Rainbow Dash as a pet. If she was a pet, she would do a lot of "pet" things that would make me feel uncomfortable.
-I don't like Rainbow Dash as a girlfriend. I am a shy guy, and I don't have any experience with girls (because I never had a girlfriend T_T). Plus, if I have a super energetic girl like Rainbow Dash around me, I would be like this since I don't like it when I am in the center of the attention:
