Ugh my dad used to have issues with his horse's tail. We had a morgan gelding, and my dad used to cut of his tail probably about half way down the lower part of his back legs, and when he started coming out less, and I was taking over his horse's exercise and stuff, I took about 6 months or so, and it grew long enough that it was dragging a good inch or so on the ground. Well one day my dad went out with one of his co workers and their kids, and when I went out the next day or something, his tail was cut off at the hocks, and my dad said that it looked better that way :(, my dad is NOT a fan of long tails. About 2 months after that, the horse, Joe, colicked and had to be put down, and I wanted to keep his "tail", and I have hardly any tail to keep. Everyone I have known has always kept the "tails" of the horses they've had to put down, and I wanted to as well.
