The wide dog collars this company offers are fantastic! They are stylish, very sturdy, decorative and are structured to automatically tighten when the dog pulls on its leash. This is the only collar that has not been chewed through, despite it's ribbon-like material! I'm thinking about getting their 'Patented No-Pull Harness'.
Everyone asks where I get my pups dog collars. These are cheap and they put an engraved name plate on them as well. No jingle-jangle since they are flat. They last forever and only $8 for a leather collar.
