I know what it's like, barely being able to keep your eyes open while studying for finals. Sometimes you just need a pal to back ou up, and keep you on your toes. For that, all you need a loyal Shiba Inu, preferably one who actually hates you, and enjoys repeatedly spraying you with water.
My dog Yuna is awesome, but she isn't really handy. I bet if I trained her how to spray water at me though, she'd enjoy seeing me suffer. To think of it, I think she just enjoys seeing me suffer in general.
