No. I raise and do basic training for guide dog puppies. The hard part is done from when they are 12-14 months, by professional trainers. You can't train a service dog when they are a puppy, unless they are simple "emotional support dogs", which I think is mostly bullshit, most privately owned dogs are emotional support dogs to a certain extent.
Real service dogs, like guide dogs, or mobility or the like, are trained professionally. Puppy educators, like me, basically raise very well behaved dogs, as a base from which the pros build.
Police and war dogs are a whole different thing.
