Well... I'm going to look at a couple mammoth donkeys tomorrow. Eeek. I've wanted one for a long time, but then again there was a time I wanted draft horses, and look how that turned out (I don't have draft horses anymore).
This pair has packed in the mountains, but they do not cross water well. They load, trim, and ride at home, but sometimes they don't feel like being ridden and they just stand there... I dunno. Can I train a donkey? I only personally know one donkey and she's wonderful but our relationship consists of petting and hugging, not working together.
My biggest misgiving is that they come as a pair. I know donkeys need other donkeys, but I kinda don't need another mouth to feed.
Anyway, apparently they're like big puppy dogs, happy to follow you anywhere and just want to be loved. They sound super sweet. Both are about 15 hands, 9 and 19 years old, gelded boys. Black with super sweet, soft grey muzzles. Pedro and Bob. :)
