Maybe an old Equus? I remember this, have
done it, it works. With or without stitches, wounds healed faster and
smoother with regular hosing, scrubbing scabs off gently. As
healing progressed some good ointment to keep edges soft seemed to help.
Seen some really ugly injuries that healed surprisingly well.
If I recall
correctly, some time ago UC Davis Vet School did a little study in which they
made an incision (it looked like a big slice) in the back of several horses
upper rear legs. They tried all sorts of different meds on these horses,
some they covered, some uncovered, and some they just hosed with plain water a
couple of times a day and did no other treatment. Big surprise, the horses
that were hosed regularly healed up better than anyone. Just keep that
wound clean, scrub the proud flesh and scabs out of it with a soft brush daily
and hose, hose, hose.
They had
pictures of these horses and these were not little cuts, they were gory
looking. Was it in Practical Horseman?
