This collar is heavy duty. It is made of quality materials and will last a very long time.
I have two mixed breed dogs with a mixture of bulldog and boxer. They chew on everything including each other's collars. Kong collars maybe last 48 hours if they survive the first 24 hours. Going on two weeks and only lost one flag patch, so far, and the collars still look brand new.
