We have a yearling Andalusian filly who got a hawthorn spine stuck in the soft tissue on the underside of her foot when just a couple of weeks old. We had to catch her and restrain her, of course, to get the thorn out and clean the wound, then catch and hold her every day to administer oral antibiotic. The experience left her very, very leary of human contact--so much so that we gave up on haltering her until this spring, when we realized we were never going to get this girl registered, turned out, or anything until we got a halter on her. In the long run, getting her to poke her nose through the halter to get bits of apple got the job done--took a long, patient time to get past her jerking her head away when I tried to buckle the strap behind her ears. But once it was on, she reared and took off for about ten yards--then stopped dead and stood there thinking. I believe she was thinking, "So this was all they wanted? What's the big deal?" because she turned around and came back, let me take the halter off and put it back on, and just went on eating as if nothing had happened. Bribery works, sometimes.
