No, horses don't have quills like a porcupine or hedgehog, they have hair.
horses just grow their hair like humans do
because that is the way the hair grows. Just like your own hair.....
like tree sap? my best guess is to give him a bath
same as it does in humans. flakey or oily skin underneath the hair. generally found in breeds with short hair like Arabs
Braid a horses mane like a persons hair, there isn't really anything different between the two.
A horses hair is longer in winter months and then it sheds out in the summer.
Horses don't have fur they have hair
yes
hair
They get very hairy in the winter... like horses the hair falls out when it gets warmer.
The hair on the horses neck is called a mane.
