Donkeys do get sick and injured just like all other animals. Thus when your donkey is sick please contact your local vet to help it and provide it with the medical care it needs. Do not work a sick or injured donkey. Sick donkeys will show signs of pain, weak, dull looks, may not eat well, tired, may produce mucous or tears, may cough a lot, may have a swollen stomach, may have diarrhoea or difficult breathing and wounds among other signs. In such cases please call a vet for help. Get Your Donkey Health Manual..
