After playing the game a few times and trying different things, I'm getting curious.

What breeds of dog/canine are Wolfstar, Hyper, and Rufus? (I can hazard a guess but I'd like to know for certain)

Additionally, why does Rufus drink BFP? as he seems to be the kind that is always in doge form. 

Wolfstar and Hyper are aliens, called wolfkin.  I designed Wolfstar as  the red wolf (Canis rufus), and Hyper after the gray wolf (Canis lupus).  As for Rufus he is a human being who drinks B.F.P. in order to be a muscular basset hound.

Ah! Much appreciated. 

I wasn't as close as I thought, I had guessed that Rufus was a beagle.

Surprised to learn he's actually human too, the thick plottens :)
