Maybe your weak genetics led you to not develop facial hair but I myself sport a rich and luxuriant beard. As for your horse analogy, breeding horses, as with breeding any animal or plant, is about selecting offspring with the desired mutation and breeding them with other plants or animals that also have the desired mutation, to increase the chances that more of their offspring will also have said desired mutation. If you want hairless dogs, you have to breed dogs that naturally, through random mutation and natural or artificial selection were born without hair. You don't just shave your dogs all the time and hope that somehow their babies get the message. Horses will never be born that have little holes in their hooves where we can neatly fit horseshoe nails. Are you really so ignorant that you believe this is how evolution works? If I were you I would do more research into both breeding and evolution, you are thoroughly and tragically misinformed, and your continued support of a completely unfounded and unsupported idea is going to make you look even more like a fool than you already are.
Here, give this a quick read

And here is a much more detailed paper, but it would require you to have a reading level somewhat above that of a prepubescent child so I have my doubts as to your ability to comprehend it, but here it is anyways
