Maybe the difference?.was ''You knew'' when it was being applied?...irrespective of the level?.:idea:
This reminds me of an analogy first told to me by Vermont Pro Trainer Alec Sparks.
Alec says imagine you are asleep in bed. You wake up and realize you need to go to the bathroom. You are walking down the dark hallway and as you shuffle along, you stub your toe on something. It hurts like heck! It startles you. You stop and maybe say "Ouch!" or something else.
Now imagine you are asleep in bed. You wake up and realize there's a tiger in your bedroom and he's pouncing and it isn't to give you a kiss. You get up and start running down the dark hallway. He's hot on your tail and you're running as fast as you can. You stub your toe on that same object, just as hard as the bathroom trip above. You barely feel it and you keep on hauling.
This gives a comparison to what our dogs feel at different times depending upon how mentally occupied they are on something else, and maybe how much adrenoline is cranking through their systems.
If you have your dog stopping to sniff at a cow pie, and you say "leave it" and give him a little bump on a 2 or 3, he may let a little "Yipe" and scoot on away from the distraction.
If you have your dog running a blind and he suddenly comes unglued hopping all around the bird crate, or in hot pursuit of a rabbit and you give him a high 5, he may barely flinch and never say a sound.
I think that just like dogs feel things differently than we do, our perception of what the dog feels can be colored by how hard our dog senses the correction due to context.
This is why one level of "correction" is not likely to always work in all situations.
It is also why we may suck it up and take our little test bumps on our arms. We're ready for it, we know it's coming, and we're in control.
