Lately again he has really started rubbing it...the whole dock of his tail has choppy little hairs. It isnt completely rubbed out but the hairs are choppy and all broken off. He is wormed regularly and the vet suggested worming for pin worms and I did. It seemed to stop for about two weeks and now its starting again. I've done oatmeal shampoo on the tail and washed it good, I've done a mix of head and shoulders dandruff shampoo and oatmeal shampoo and I've also done medicated spray from Mane and Tail and MTG to no avail. No matter what I put on it he still rubs it. I Soaked his tail in MTG and wrapped it the other night but it still looks the same, but now under his tail around his rectum and dock it looks like he has flakey skin. (like when you get sunburn and it peels)
My mare has it also. Hers almost looks like someones biting her tail in one spot. I noticed her trying to rub her butt on the fence today and shoo'd her off. She's on the same worming schedule as my gelding and I've done the same things to her that I've done with him with no avail still. The other horse in our pasture has none of these problems..
It doesnt help that im trying to grow my mares tail because we have an upcoming WP show and at the last one her tail looked terrible.
Any suggestions are greatly appericiated!
