Re: Equine radiology
You are likely in more danger from being kicked than the scatter radiation. The old Picker army field portable x-ray machines had a "wind up" exposure timer that would scare the hell out of the poor horse as it buzzzzed counting down. I had to replace tubes, cables or plugs on those units about every 30 exposures when used by the vet.
Thinking back on it; it was never the same person that brought the units back to the service office. I only hope that the operator fared better than the equipment.

What was the exposure time? I would assuming exposures
would be similar for a hoof and a human patient knee,
70 kVp, 5 mAs for 28 mrad entrance dose. If the time
is doubled, the mAs doubles, and the entrance dose
doubles.
Where was the handler standing? If not in line with
the primary beam, which I assume not, the dose would
be from scatter and leakage radiation. Probably in
the order of a couple of mrem. The handler should be
wearing a leaded apron.
I assume radiation risks were explained to the horse.
