They didn't so much choose it as decided to go along with what someone else was using to represent them.
The first time the donkey was used in connection with the Democratic party was during Andrew Jackson's presidential campaign when his opponents tried to label him a "jackass" (Jackson the jackass). Jackson turned it around and used it as his own symbol on his campaign posters. His opponents used it again to characterize his stubbornness in refusing to re-charter the national bank. It got dredged up again after he left office but still though of himself as the leader of the Democratic party. In a political cartoon, Jackson was shown trying to get the donkey to go where he wanted it to go. The cartoon, published in 1837, was titled "A Modern Baalim and his Ass." In this case the donkey was representing the Democratic party rather than Jackson - the first time the donkey actually represented the party rather than a member of the party.
Years later (starting around 1870) the famous political cartoonist Thomas Nast used a donkey to represent the Democratic party and party members in his Cartoons. His cartoons are also established the Elephant as the symbol of the Republican party. It is unlikely that Nast ever saw the Jackson cartoons since he didn't emigrate to the US with his parents until 1940 when he was six.

The main political symbol for the US Democratic Party is the donkey, ideally incorporating at least a couple of stars and the colors red, white and blue. A couple of years ago, the Democratic Party tried out a new logo, of a white letter D on a blue background, meant to evoke D for Drive versus R for Reverse, but its public reception was underwhelming. Most people know it only from Jon Stewart's ridicule. Thus, for the time being, they're sticking with the donkeys.

It is a donkey and the now-famous Democratic donkey was first associated with Democrat Andrew Jackson's 1828 presidential campaign. His opponents called him a jackass (a donkey), and Jackson decided to use the image of the strong-willed animal on his campaign posters. Later, cartoonist Thomas Nast used the Democratic donkey in newspaper cartoons and made the symbol famous.
