Can be quite a bit longer..Some have been known to live into there Late 40's~! SO getting and having donkeys is definitely a live long commitment,
Miniature Donkey Talk Magazine and The International Miniature Donkey Registry along with Pheasant Meadow Farm in Westminster, Maryland USA Welcomes You!
With proper lifelong care, 25-40 years
36" or under (IMDR Class A Registry), 38" or under (IMDR Class B Registry)
200 to 450 pounds
Any age male is called a Jack
Any age female is called a Jennet
With life long proper care, donkeys can live well into their 30's (although I personally had a jennet who lived to be 47 years of age) and jennets can produce foals into their early 20's. Older jennets are normally wonderful mothers and fantastic baby sitters to put in with foals being weaned.
