I use a martingale.
His seat belt for the car is a harness. I was in a rush and clipped his leash onto it when we were going into the vets. I had no control. It was a nightmare. I like the martingale. He must know the difference, because he is very easy to handle with it.
He is 10 months and 78 pounds, but we started his training with the martingale when he was 3 months.

He will always be in my heart.
