may I ask, I see you have experience with dogs'Course.
I'm just saying for this specific case.
Some dogs can get a bit over-excited so rewarding them just makes them more excited and forget about the rule.
Basically, you're turning yourself into a horse here. Tug on the Reins, and we stop. Keep it slack and I follow.
Dogs are quite smart and can handle things without the feedback for simple things.
Want them to do complex stuff like shake or roll over? Then reinforcement is necessary to make things clear.
