Every year several horses
in my neighborhood, including one or two at my place, get a condition
similar to what you're describing. Some of us have vets check it & give
advice, and some of us just confer with our neighbors on what to do. We've used
fungicides, betadine washes, tea tree oil washes, or nothing on
it, and it always clears up as their spring hairs grow in. It feels
better to do something, though, and since this is the buffalo gnat season as
well, tea tree oil washes are a good choice. Good luck and hope it's
nothing serious.
The farm where I field board is
currently suffering from an epidemic of hairloss. Most of the 20+
horses have patches of hair loss or areas where the hair is broken off at the
skin surface in large irregular patches - look like they've
been shaved. At first I thought it was due to rubbing, but it
is showing up on areas that would be impossible for a horse to rub. It
does not look anything like rain-rot (no scabs, bumps or dust), and does not
appear to itch or be sore.
Any suggestions as to cause or treatments
would be most appreaciared. My vet is treating several of the horses
and is not sure what is going on.
