Dandruff on horse tail

Hi, my horse has these last days a lot of dandruff on his tail, it started a week ago, his Bone tail had a kind of oily stuff coming out of the skin but after it started to be flakey and now hé s looking some hair. He s not itchy AT all. Somebody knows what it could be and which treatment would be the best? I ll post some pics, tia.


The first thing I go to is dandruff shampoo and take it from there. Soap it up well and let it sit for a couple of minutes before rinsing. Did you check underneath his tail? He could be rubbing the tail (and your not seeing it) because he need a cleaning under there.

That bald spot means he’s rubbing.

His sheath may need to be cleaned.

Or his anus cleaned/wiped with a baby wipe.

I load mine up with MTG because I know she tolerates it but alternatively I use a combo of castor and vitamin e oil. Lather it in. Next day or two days later shampoo with head and shoulders. It’s always worked well for me. I make sure to really get the dock and entire anatomy super clean and then meticulously rinsed.
