Compared to a horse, the detection of sickness and disease in a donkey can be made more difficult by its stoical nature.
Dullness and depression may be the only symptoms exhibited by a donkey, and this could be a warning of a potentially very sick animal.
While a healthy donkey should be alert and aware, interested in what is going on around him, with ears pricked, a donkey in pain will often stand with its head lowered, lie down or not respond as it normally would.
In Merkato Market, it is unfortunate that many donkeys seem dull and depressed. It is a place where donkeys are literally treated like machines. The Donkey Sanctuary has a clinic here to alleviate their suffering.
