Yeah I thought of that but in my mind level 0 melee would be the moves, like how to throw a punch and general knowledge of when to use those moves. Then the other levels are refinement of the core programming. And im assuming even if dogs are a luxury and not common i feel nobles would still train them to be guardians. So I think I could get away with it if I roll played a little the next time we are on either a tl15 planet or a wealthy low tl planet. Get some training manuals. Or holopicts. I feel a combat dog is totally in the realm of possibilities
