Erich Steffensen
Dogs: Rush, Java, Moshi
Totally converted to dog sports.  He doesn't talk much but will give your dog a massage as long as there is no public display of emotion.  A member of the border collie Frisbee cult, you will find Erich practicing throws, training one of the EyeSpylets, or whipping up an awesome guacamole.  Don't worry if your dog follows him home, he works as a butcher and has been known to have raw marrow bones with him.
