Ha my bay gets into the cockle burr patches all the time! I don't know how he manages to get into them and how my bestfriends horse doesn't. But he has never got them that bad.
Peanut butter works very well. Most people use it to get gum out of their hair so they won't have to cut it. Im not sure how it works.
