Teacher

Teacher is the dog trainer for the Hangdogs in 2253.

Background
The Dog guru, Teacher, has been the master dog trainer for many years. He is a bit of a nomad, sleeping outside, with his dogs. He has a bit of shelter to protect him from the environment.

He keeps his methods a secret but it's not entirely impossible for someone to coax it out of him. He is in charge of all the dogs, knowing them so well and will only sell directly to visitors if he approves of them.
