It's a tendon injury, and it will heal on its own schedule if I don't aggravate it again. X-rays won't reveal anything. There's nothing to really check.

I assume the goat's tennis balls are to protect others. Several pack goats had less fluorescent and smaller horn protection if the horns hadn't been burnt away entirely. That is a stinky job,so I completely understand choosing the blunted protective coverings instead.
