Donkeys evolved from the desert. Donkeys’ fur and hooves do not like to stay wet.
Seems like spring is the time of the year our donkeys need the most help with the itchy fur and they are more prone to sores and need us, humans, to be checking them over each and every day.
Bald patches on donkeys are normal. Donkeys have longer hair than a horse. Donkeys are more susceptible to rain rot than a horse. Make sure your donkey has access to shelter as clumps of hair fall out and bald patches develop. Check for Lice. Oil-based products work much better than powders due to the donkey’s thick and long fur coat.
As soon as the weather is 70 degrees give a good bath with antiseptic soap and cream rinse. I never spray water in my donkeys or horses’ faces. I wash gently with the washcloth. Select Virbac Epi-Soothe Shampoo
If after doing all of the above your donkey still has lice and sores contact your vet. Ask for a full physical and blood tests for Cushings. Sadly, the immune system is attacked when a donkey, horse, or mules has Cushings.
GOD bless you and your family two and four-legged!
