For Caine i use a response collar.
I was told not to use a harness by my obedience trainer as all their strength comes from their chest and that a GL was not goo until they were full grown as their snout is too small and it sits to close to his eyes.
So I went out and got a Response collar. So it has a stopper on it it goes around their head and sits at the top of the neck ( where it is most soft) right under their ears and below the jaw. so when i walk him i can give a little jolt and he will stop pulling. I have used it on him a few times when walking and i have only had to do a little jolt here and there.. it seems to work wonders......
What type of "Jolt" are you talking about......
If its a literal jolt you might want to read the rules of this forum again. Not trying to be mean, just trying to inform you before a Mod does.
If Im mistaken please forgive me.
