I watched that common sense video when I was looking for a training vid! It's good.
An illustration which might be helpful: From what I learned researching prior posts here and videos elsewhere, and being the kind of person who appreciates structure and planning, I decided to work my puppy for eight weeks on the same five commands after some playing, in a quiet area with low distractions, always on a leash. I gave him a week with each command before starting a new one. The first was sit
--for everything: play, walks, potty, whatever. Next was come
, and I would tug the leash gently so I could correct him and walk him toward me. Then down
, treat close to the chest and lowered to the floor from a sit position. Then we did up
, with me saying this a little animated and taking a step back, which got a perky response initially, enough for him to eventually "get it." We're stuck on stay
at the moment...he's more likely to flop on his side, tongue lolling, smiling, but I get a good ten to twenty seconds out of him right now. Up has actually been a good one for being out in public with this particular dog. He's low energy and will likely lie down while I'm talking to someone. The up avoids me having to give him a gentle tug to get up and going.
It's all been in good fun (no reprimanding) because of his age, but I was also careful about how I carried myself, because it was not simply play. I dropped using his name during training sessions so he could latch onto my voice + 1 command = do. He's doing great and can go to the yard off leash and perform. I've also switched to not treating every time, alternating between praise, treat, or simply the next command, and he can do all five in sequence.
At an early point, I realized he was purely responding to the sound of my voice, not necessarily the action I wanted, so we did a *lot* of short sessions to help reinforce the verbal sounds, maybe ten minutes, rather than prolonged work that could be confusing or mentally tiring. I'm starting to call commands from other places rather than just standing in front of him, too, which I had nooo idea was a thing to do, and it's a whole new ballgame. He'll start more formal training in another month or two when I feel he has a good grasp of these basics.
Anyway, that's worked for this particular dog, your mileage may vary. There are many ways to skin a...carrot?
