I'm hoping some of our pit owning members can answer this question for me. I've seen quite a few of these dogs wearing huge, about 2-3 inch wide collars. I'm wondering why. Is this just a trend or do these very wide collars serve some other purpose? Usually I only see this size on sighthounds and even then they don't appear to be as big. I know the Pits I've worked with have done just fine on a regular leather collar, so just wondering if I'm missing something?
