I use one on Bon now because he is such a big boy and a lot to handle. I feel much more in control. I've thought of trying a martingale collar but I'm not sure where I could get one to slide over his big ol' head
Some of the martingale collars have snaps, so you can adjust it to size & snap it on around the neck like a regular collar instead of putting it over the dogs head.
