Dry, Itchy, Flakey Tail Bone - at my wit's end

[foxyqh]

My mare did this until we got good coconut oil and rubbed it in her tail bone daily. All the hair has grown back and is now thick, shiny, and no more rubbing

Have you checked for pinworm eggs around the anus? They are sometimes the cause of extreme tail rubbing.

For those pinworms: Anthelcide EQ
no more tail rubbing if it is pinworms. Put it in your worming rotation
