I prefere a choke chain, yesterday I had to use it with Misty and I was walking Blair as well so out came the coupler, and well Misty normally wears haltie, which was not really work well when using a coupler lol and it was not bad at all, she choked herslef far less then she does on a normal collar. Shadow was trained with a chcoker, she LOVES it lol I am not kidding, she hates the leash being on her regular collar and will pull and be a jerk, but she gets so exited to see the choke chain, and proceded to walk in a perfect heel and be a sweety lol. Shadow however has a very very thick ruff, so on her the choker would do no more then tickle lol
