Has a loop on the end so you can hook it on the puller or pull on it to keep the calfs head coming the right way when you pull him up into the birth canal. A calf that has his head back can be a real problem. Usually the cow has been straining a lot and he is pretty much like a dish cloth.
If you don't have a snare it can be extremely tough to keep that head pulled around. The best way is put your thumb and index finger in his eye sockets as you pull. Get a red eyed calf and an awful sore arm!
