Donkeys have distinct physiological and behavioral needs that differ from horses, and their welfare is frequently compromised by being managed as if they were small horses.
Donkey welfare suffers from a combination of species-specific misunderstanding and global neglect. In developed countries, donkeys kept as companions are often obese due to inappropriately rich pasture and inadequate exercise - their efficient metabolisms evolved for sparse grazing. This obesity predisposes them to painful laminitis and potentially fatal hyperlipemia when stressed. Working donkeys in developing nations face the opposite problem: overwork, inadequate feed, untreated injuries, and lack of access to veterinary care. The Brooke and other organizations working with working equids document widespread suffering including poorly fitting harnesses causing wounds, untreated eye conditions, and chronic lameness. Donkeys deserve recognition as distinct from horses in their specific welfare needs.
