Hello, when I was recently grooming my 15 year old half-leased horse, Emerson Blue, on the dock of his tail was bare. It looked like he had rubbed of all of his hair. My trainer had told me to put a medication called MTG (Mane Tail Groom) on his dock. She had also told me that he could have worms. So I apply the MTG for 3 days and it had shown no signs of regrowth... I guess my question is, Does my horse have worms?
My horse is having the same reaction. I got a fecal done and because she is on a herd health program and I didn't want to over do it with the deworming. She came up negative for parasites and the vet said that with this summer it is mostly due to dry skin seeing as I regularly clean my horse's udder. They reccomended using betadine soap mixed with mineral oil and washing it off or vitamin E cream. One of the problems with using MTG, which I have had success with, is that it is very oily and with the turning out in the sun, you are basically just cooking your horse's dock.
