When talking about adding dog breeds. It would have been fun to have a Standard poodle in phantom colloring that is technically and can fix damaged electronics for example. Poodles is one if not the smartest of dog breeds. If you need a tinkerer that's is.
He can have simple kennel utility clip / cut, it is essentially a short cut. Please google phantom poodle and look if it is something you are up for. My phantom poodle can step in as a model if you want.
Mine poodle is always happy, inventing humorous things, and never angry. He is silly (in a fun way).
This is just an Idea. It's your story so..
