1. Their “stubbornness” is a survival instinct
Donkeys are often called stubborn, but this is a misconception. Unlike horses, which are “flight” animals that run when scared, donkeys are “fight” animals. When they sense danger, they will often freeze and refuse to move until they have had time to assess the situation and determine it is safe to proceed. This is a survival strategy, not a sign of obstinance.
2. They are natural-born protectors.
Donkeys have a strong, natural dislike for canids like dogs, coyotes, and foxes. Because of this, they are sometimes used as “guard donkeys” for herds of livestock, such as sheep or goats. They will aggressively defend the herd from predators, and the other animals will often gravitate toward them for safety.

3. Their ears are multi-purpose marvels
Donkeys’ large ears are more than just for hearing. They have a high density of blood vessels, which helps them dissipate heat and stay cool in their native hot, arid climates. They can also rotate their ears to pinpoint sounds from miles away, allowing them to communicate with other donkeys over vast distances.
World Donkey Day is celebrated every year on May 8th to raise awareness about the important role donkeys play in human lives and to advocate for their welfare.
4. Their bray is unique among equines
The donkey’s characteristic “hee-haw” sound, or bray, is unique because they can vocalize while both inhaling and exhaling. The “hee” happens on the intake of air, and the “haw” on the exhale. This ability is not shared by horses or zebras.

5. They form deep, lifelong friendships
Donkeys are incredibly social animals. They often form very strong, lifelong bonds with other donkeys or with other animals they live with. When a bonded pair is separated, the donkeys can become extremely distressed and even ill from the separation.
The American Mammoth Jackstock is the largest breed of donkey in the world, with the tallest living donkey, Romulus, standing at 17 hands (5 ft 8 in) tall.
6. They are more intelligent than they are given credit for
Donkeys are highly intelligent and have an excellent memory. They can learn and problem-solve at a similar pace to dogs and dolphins. Their sharp memory means they can remember places, routes, and people for many years.
7. Their digestive systems are incredibly efficient
Donkeys evolved to survive in desert environments with sparse vegetation. Their digestive systems are so efficient that they can get up to 95% of their nutrients from plants that other animals might find indigestible. This makes them prone to obesity and health problems like laminitis if they are allowed to overgraze on rich pasture.
The smallest breed of donkey is the Miniature Mediterranean Donkey, which is a popular pet and typically stands no more than 36 inches tall.
8. They are a foundation for unique hybrids
Donkeys are closely related to horses and zebras and can breed with both. A male donkey (jack) and a female horse produce a mule, while a female donkey (jenny) and a male horse produce a hinny. A zebra and a donkey can also mate to produce a zonkey or zedonk. These hybrid offspring are almost always sterile.
