My friends have a very large black dog that acts as sentry on their hilltop home in the Sierra foothills. He is a great dog with a 22" neck. I made this gun oriented tooled collar for him. I've made many dog collars but this one has all the bells and whistles and took longer than expected to make inbetween other projects. Those are deactivated .38 Special cartridges in those loops. They will let the dog wear this on special occasions like their huge two day two keg parties they have up there.
