I’m reviving this thread because my donkey’s doing it again!
This time, I did a google search, and came up with this:
Every spring on various donkey lists, newbies “panic” because their
recently-acquired donkeys suddenly have developed large bald patches.
We’ve taken to calling it the Donkey Depilatory Disorder—it seems
that stress, or maybe excess rolling (which donkeys do to “claim” new
territory) will remove the old hair before the new has fully come in.
It usually takes 2 or 3 weeks for the condition to resolve itself, as
the summer hair finally emerges from the skin.
It’s from this address: http://www.mail-archive.com/fjordhorse@angus.mystery.com/msg03733.html
I just thought I’d include it in case anyone else didn’t realize this was, I guess, normal.
This year, I’ve been pulling out her hair, kind of like you can do to dogs when they are shedding – some dogs have clumps of fur you can just pull out. So does my donkey. She must really like it because she stands still in the field while I do it, with no halter or anything so she is perfectly free to walk away. But she doesn’t, she stands there very contentedly. This year, her bald patch is HUGE, from the withers to where the cantle of a saddle would be, if she ever had one on.
Last year her patches regrew fur quickly.
So I guess this is just an FYI for those with patchy molting donkeys.
