Bocks Cattle Identi Company makes the famous Dewlap Identification tag the Boc-Loc
The Boc-Loc tag is made of non-rigid plastic. Tag is applied into the brisket, an area with few nerves in the skin, the tag is always and easily visible and will not snag like ear tags can.
The plastic covered metal hasp prevents infection.
If you're in a geograph where you can easily lose ear tags try Boc-Loc. These Dewlap tags stay in year after year.
To apply- put at the junction of the neck and brisket. First clip/shave hair with clippers and use the punch applicator to put a hole through the loose skin. The U-shaped plastic- coated hasp is placed through the hole and the tag placed over the hasp. The ends of the hasp are bent back and over to hold the tag in place.
