Got a big dog? This collar is made tough for the strongest of dogs! It is a double thickness of 10 oz. cow hide, 2" wide in front tapering to 1" at back for buckle. The buckle and ring are solid brass as well as the engraved name plate. The dots on this one are silver and gold in a zig zag pattern. This collar is a slate blue color but tan/brown, black, oxblood, red, green, or chocolate brown are also available. To measure your dog wrap a tape measure around his neck and add 1" to get your measurement. The collar will measure that measurement to the center of 5 holes at 1" apart.
