Yeah. Teaching dogs how to do things is actually pretty easy IMO. But obedience is absolutely useless if you have behavioral issues and poorly adjusted dogs.
You will get way further with your dog if you spend the little puppy time getting them proper environmental exposure, showing them what's expected in the house and getting them used to being crated, handling, grooming and appropriate sleep, meal, and bathroom schedules.
As for the e-collar, you nailed it. Pressure is pressure. Whether it's the prong collar, choke chain, spacial, or e-collar it doesn't really matter. I just want a dog who understands that pressure isn't bad, it just is. And that they're in total control of turning it on and off.
Once that happens, the e-collar can be used as a gas pedal or a brake.
Something I learned from Michael Ellis is, spend the time teaching the dog the skills they'll need to learn how to learn and everything else comes together rather quickly.
