We’ve all seen them. You’re scrolling through a feed of doom-posts and political arguments when suddenly, there it is: a fuzzy, gray face with oversized ears and a set of teeth that would make a Victorian ghost jealous. Pictures of donkeys smiling hit different. There is something about that wide-mouthed, gummy grin that feels more honest than a golden retriever’s wag or a cat’s indifferent blink.
But here’s the thing. They aren't always "smiling" because they heard a funny joke.
Donkeys are misunderstood. People call them stubborn. They call them "beasts of burden." Yet, if you spend ten minutes looking at a donkey with its lips curled back, you’re going to feel better. It’s science, or at least, it’s biology and psychology crashing into each other. We are hardwired to respond to these expressions, even if the donkey is actually just trying to figure out what you had for lunch.
The Flehmen Response: The Truth Behind the Grin
When you see pictures of donkeys smiling, you are often looking at a biological process called the Flehmen response. It’s not a smile in the human sense. Basically, the donkey curls its upper lip to expose the vomeronasal organ, also known as Jacobson's organ. This helps them "taste" scents in the air.
They do it to analyze pheromones or unusual smells.
If you walk into a paddock wearing a new perfume or carrying a bag of salt and vinegar chips, a donkey might "smile" at you. They are literally pulling air into a specialized duct to see what’s going on with your chemistry. It looks hilarious. It looks like they’re laughing at your haircut. In reality, they are just being very thorough detectives with their noses.
However, don't let the anatomy ruin the vibe.

Ethologists—people who study animal behavior—have noted that donkeys do show signs of contentment that mirror what we interpret as happiness. A relaxed donkey has soft eyes, droopy ears, and a neutral mouth. When they are truly engaged or excited, like when a sanctuary volunteer they love walks in, their whole face changes. While the "tooth-baring" Flehmen response is a sensory tool, donkeys also have a range of facial expressions that communicate genuine social bonds.
Why We Can’t Stop Looking at Them
There is a reason these images go viral on Google Discover and social media. It’s called anthropomorphism. We love to project human emotions onto animals because it makes us feel connected to the natural world.
When we see pictures of donkeys smiling, our brains release oxytocin. It’s the same chemical that hits when you see a baby or a puppy. Donkeys have these massive, expressive eyes and "long" faces that lend themselves perfectly to our desire to see a "mood." A donkey's face is a canvas for human empathy.
The "Donkey Sanctuary" Effect
Organizations like The Donkey Sanctuary in the UK or Safe Haven Adoptions in the US have used these images for years to change the narrative around these animals. Historically, donkeys were treated as disposable tools. By sharing photos of them looking joyful, these groups have successfully pivoted the donkey's public image from a "stubborn mule" to a sentient, emotional companion.
It works. It really works. You see a donkey "laughing" in a field of daisies, and suddenly you’re looking up how to sponsor a farm animal.
Real Examples of Famous Smiling Donkeys
Take the case of "Laughing" Jack, a rescue donkey whose photo made the rounds a few years back. He wasn't just doing the Flehmen response; he was mid-bray. When a donkey brays, their entire body gets involved. Their neck stretches, their mouth opens wide, and their teeth are fully on display. To a camera lens, it looks like the punchline of the century just landed.

Then there are the "miniature donkeys."
Miniature donkeys are a specific breed, originally from the Mediterranean islands of Sicily and Sardinia. They are tiny—usually under 36 inches at the shoulder. Because of their scale, their "smiles" look even more exaggerated. Their heads are large relative to their bodies, making every expression look like a Pixar character come to life.
Does a Smile Mean They Are Happy?
Context is everything. You have to look at the ears.
- Ears forward: They’re interested and likely "smiling" because they’re curious.
- Ears pinned back: That’s not a smile. That’s a warning. If the teeth are out and the ears are flat against the neck, back up.
- Ears floppy/sideways: This is the jackpot. This is a relaxed, happy donkey who might just be enjoying a good scratch behind the ears.
The Mental Health Benefit of "Cute" Content
We live in a high-cortisol world. Looking at pictures of donkeys smiling isn't just "wasting time." Research from Hiroshima University found that looking at "kawaii" (cute) images can actually improve focus and performance on tasks. It triggers a "caregiving" impulse that slows us down and reduces heart rates.
Donkeys are particularly good for this because they aren't "perfect" like a show horse. They are scruffy. They have knobby knees. They are the underdogs of the equine world. Seeing an underdog look happy is incredibly cathartic for humans.
How to Capture the Best Photos of Your Own
If you’re at a farm or a sanctuary and want to snap your own pictures of donkeys smiling, you need to understand their triggers. Don’t force it. Donkeys are incredibly sensitive to energy. If you’re frantic and shoving a phone in their face, they’ll just walk away.

- Scent is the key. Bring something with a strong (but safe) smell. A piece of peppermint or a fresh apple can trigger that Flehmen response.
- Wait for the bray. If you hear one donkey start to "hee-haw," get your camera ready. The physical motion of a bray is where the most "expressive" toothy photos come from.
- Low angles. Getting down to their level makes the donkey look more "human" and less like a farm animal you're looking down on. It highlights the jawline and the mouth.
- The "Scratch Spot." Most donkeys have a sweet spot at the base of their neck or just behind the ears. If you find it, their lip might start to quiver or curl. That’s pure bliss.
The Ethical Side of Donkey Photography
While we love these photos, it's worth noting the limitations of what we see online. Sometimes, "smiling" photos are captured during moments of distress or when an animal is being teased with food it can't reach. Expert handlers at places like Peaceful Valley Donkey Rescue emphasize that while donkeys are stoic, they feel stress deeply.
Always ensure the donkey has the "right of refusal." If they turn their back on you, the photo session is over. A real smile—or at least a real moment of connection—can't be forced.
The nuance here is that donkeys are smarter than we give them credit for. They have a memory that rivals elephants. If you treat a donkey well and capture a photo of them looking "happy," you’re capturing the result of a bond. That’s why the best pictures of donkeys smiling usually come from sanctuaries where the animals finally feel safe after years of neglect.
Putting the Joy Into Practice
Next time you feel the weight of the world, don't just look at one photo. Look at a gallery. Observe the way their whiskers catch the light. Notice the weird, horizontal pupils in those big brown eyes.
Actionable Steps for Donkey Lovers:
- Support Sanctuaries: If a photo brings you joy, consider donating to the source. The Donkey Sanctuary (UK) and Peaceful Valley (USA) are the gold standards for care.
- Learn the Language: Read up on equine body language so you can distinguish between a "scent-tasting" grin and a "leave me alone" grimace.
- Visit in Person: Use sites like "Visit My Farm" to find local rescues. There is nothing like a donkey lean—when they lean their whole weight against your leg because they trust you.
- Digital Detox: Replace your morning news scroll with a five-minute search for "rescue donkey transformations." It genuinely resets your brain's baseline for the day.
Donkeys don't have much in this world, but they have a spirit that seems to transcend their circumstances. Whether it’s a biological quirk of their olfactory system or a genuine expression of a life well-lived, a smiling donkey is a reminder that even the scruffiest among us can find a reason to show some teeth and enjoy the sunshine.
