Horses/Ponies can't really "break" their dock, their tail can be ripped, and uneven if it was caught on a fence, so it is then usually cut clean again, and a horse who has been a racer in the past may have been "docked" which then means it's tail cannot grow back to the lenght it was, meaning it is also more proned to flies in summer and needs more care taken of it then horses with long tails.

The tail head is the base of the horse's tail. It is also called the "dock."
the dock is the tail... the hair is the tail the soild bit its attched to (which is quite short) is the dock.

The tail of a horse consists of two parts. The dock and the skirt. The dock consists of the muscles and skin covering the coccygeal vertebrae. The term "skirt" refers to the long hairs that fall below the dock. It has a curvy shape, with small tufts of thick hair.
it may be at weird angle if they broke it and if you feel the tail you will feel a lump or a gap
Tail docking was orignally done to prevent the tail from becoming entangled in the harness of draught and carriage horses. Today, it is done infrequently and more likely to be done to draught horses.
