I have a GSD puppy that I am training in SAR. Many SAR dogs I've worked with have little to no obedience training or impulse control. By doing obedience, will I reduce the dog's drive? I want to retain or even increase her drive but I don't want a monster dog either. Is it worth it to train her in obedience and impulse control? Are there certain commands you wouldn't teach your working dog (such as drop it/wait/no pulling on leash/ etc)?
