Mav barely ever wears a collar..he has always worn a harness but now that he is getting older id like to get him a tag collar and perhaps a martingale for walking because he has started to pull now that he realizes how strong he is. these keep safe ones sound really cool tho. I know shaka has some nice collars if youre just looking for one that is nice and not a "special" one that serves a purpose other than being a collar..they have martingales there too i think. they have a sale on now too
