Horses have much more sensitive skin than cattle.
A horse will be shredded by a barbed wire fence...a cow will plow through it and
never even get a nick or a drop of blood. Some horses, including mine, as
so sensitive to prickles that they become very upset when passing through
thistles or nettles (particularly the latter.) Cows would never even feel
them. So, one cannot compare the two animals for skin
sensitivity.
After reading this, people will come back and say, " but
horses and cattle aren't like people. They have thicker skin. They don't
feel it like we do." And the saddest part is they actually believe
it. As long as people continue to convince themselves this does not
hurt, they will continue doing it.
