"The Traditional Gypsy
Horse will have huge, flat bone. His body must be comparitively short. He
will have a thick neck and a long shoulder, which should tie in well down
his back. He should have a wide and powerful chest. His hindquarters
should be round and large. He should sport a very thick mane and tail.
His feet should be covered with an enormously profuse amount of long hair.
This should start behind the knee or hock and fall to the ground. It is
known as Feather. Feather can be noted as curly, woolly or straight and
silky within the breed. Many prefer straight, silky feather but it is not
usually demanded. What "is" demanded, is that there is profuse Feather
which covers the hoof."
