My dog became over stimulated by the bark collar while walking and bit my leg. Did I address this situation correctly?

Cindy,

I am writing to see if I am going in the right direction. I was walking my blue heeler/ border collie, Blu. He was wearing his tri tronics bark collar. He's been using it for over a year.We had just seen 5-6 does on our last walk, he was pretty excited about that. Next walk, two little shi tzu puppies approached from about 25 feet away. Blu began the long howling barks, you could hear each time he barked the collar set at 4 shocked him, and he just kept going off. This was the 1st time he's ever displayed "over stimulation" from this collar.

He's normally a dominant dog, but not dog or handler aggressive. I began to reconduct him away from the approaching dogs back to our garage, he would not give up on barking and snarling. He gets walked on a prong collar (plasti-dipped prongs) with a dominant dog slip collar - he has a tendency to pull when were on a pleasure walk without it. I normally will put myself between him and whatever he's fixated on, at arm's length. I got bitten in the thigh, I didn't mark the behavior because frankly I was shocked, but he was very aware he'd done something wrong.

I walked him home immediately and he's been in his cage continuously since, like just starting over with the week of cage / no freedom, like when he was a puppy that 1 week Ed instructed in the groundwork video. Is this the correct way to address this issue? I just don't know what else to do to re-assert my dominance over him.

Thanks,
Alex
