Need to grow a horses tail faster!!!?

Wrap her tail in vet-wrap (it wont slip like a tailbag) and leave it like that while your gone so she cant rub it and other horses cant eat it. also invest in a fake tail (made out of real horse hair from other tails, dont worry, they do not get it cruely, they just cut it off) for showing, you wont want to show her with a 6 inch tail. this is just what i've done with my horse who loves to rub and itch his tail, causing it to be like 2 inches at the top and long at the bottom xD
