Dipped or swayed backs are a conformation fault, unless in old animals or brood jennies who have produced many foals, and not due to genetic factors. The mane and tail in the donkey are coarse. The mane is still and upright, rarely laying over and the tail is more like a cows, covered with short body hair for most of the length, and ending in a tasseled switch. Donkeys do not have a true forelock, although sometimes the mane grows long enough to comb down between the ears toward the eyes. Because the mane is stiff and sometimes flyaway, many donkeys, especially show stock, wear their manes clipped short or shaved close to the neck.
Hoof shape varies as well, donkey hooves are smaller and rounder, with more upright pasterns.
The legs should have good bone, but many donkeys of common breeding may appear to have long thin legs with tiny feet. Larger Asses such as the Poitou or Andalusian types may appear opposite, with huge, heavy shaggy legs and large round feet. Good legs and feet are essential for breeding mules, as a good foot is much preferable to a large body on tiny stick legs and feet. The vocal qualities are the frequently remembered differences in the long-ears. Although many donkeys are the familiar gray-dun color, there are many other coat shades.
