With a face only a mother could love, or a devoted pet owner at least, “ugly” dogs bring a whole heap of joy to their human families. They might have wonky teeth, a tongue that never quite stays put, patchy hair, or a proud wobble in their walk. The point is, none of that gets in the way of being someone’s best friend. Ugliest Dog Day leans into that idea with a wink: it’s not about ranking animals by looks so much as celebrating the perfectly imperfect pups who prove that charm, personality, and companionship are the real showstoppers.
In practice, the day works best when “ugly” is treated as affectionate shorthand for unusual, not as an excuse to mock. Many of the dogs that get called ugly are seniors, rescues, or dogs whose appearance changed because of an injury, a skin condition, or a genetic quirk. Their stories often highlight resilience and good care, which makes the celebration feel less like a joke and more like a reminder that love is not limited to photogenic faces.
How to Celebrate Ugliest Dog Day
Enjoy Ugliest Dog Day with some of these ideas for celebrating the day:
Host or Follow a “Ugly-Cute” Photo Share
Ugliest Dog Day is tailor-made for sharing the kinds of photos that would never win a glossy calendar contest, but still capture a dog’s heart. Friends can trade pictures of underbites, bedhead fur, crooked smiles, and the many strange sleeping positions that only dogs find comfortable. Keeping captions kind matters. The best posts read like affectionate teasing, the same tone many people use when they call their own pet a little goblin and then immediately hand over a treat.
For anyone who wants to make the sharing more meaningful, the theme can be paired with a small act of support for animals who get overlooked. Shelters often have dogs that are harder to place because they are older, have scars, are missing hair, or simply do not photograph well. Sharing an adoption spotlight, donating supplies, or sponsoring an adoption fee turns a goofy social post into something that actually helps.
Show Some Appreciation to an “Ugly” Dog
Have an ugly dog yourself or know someone who does? Ugliest Dog Day is an ideal time to spoil that dog with a little gift. Buy a new toy or a little treat to chew on. Delight them with a new dog bed or just pick up an extra box of favorite biscuits.
Of course, the best gifts often look less like shopping and more like attention. Many dogs would choose time over toys any day of the week. A long sniffy walk where the dog gets to set the pace, a trip to a quiet trail, or a session of backyard games can feel like a luxury. Dogs with “ugly” features are sometimes dogs with special needs, so celebrations can be tailored to what actually makes that individual dog comfortable. A senior dog might want a slow stroll and a soft bed. A hairless dog might appreciate a cozy shirt if temperatures run cool. A dog with dental quirks might prefer softer treats that don’t hurt to chew.
If gifts are on the agenda, choosing items that support comfort and health is a thoughtful way to keep the day from being just a joke about looks. A well-fitted harness can be a game changer for dogs with delicate throats. Puzzle feeders are great for mental enrichment and can keep energetic dogs busy without overdoing physical exertion. Grooming tools can also be a kindness, especially for patchy-coated dogs or breeds with sensitive skin.
A dog park visit can be fun, but it’s not a universal good time. Some dogs, especially those with limited vision, mobility issues, or past trauma, can find the chaos overwhelming. In those cases, a quieter alternative still counts as a celebration: a one-on-one playdate with a known friendly dog, a calm training session with high-value treats, or even a car ride with the windows cracked just enough for intriguing smells can feel like a party.
Learn About the Dogs Often Labeled “Ugly”
One fun way to celebrate Ugliest Dog Day might be to learn a bit more about dogs that are commonly described as “ugly.” Beauty is in the eye of the beholder, but some looks tend to get labeled unusual: hairlessness, underbites, prominent eyes, heavy wrinkling, or a mix of features that does not match any one breed standard.
It’s worth noting that “ugly” is usually code for “unusual by mainstream pet-photo standards.” Many of the dogs labeled as ugly are actually quite striking, and plenty of the traits that get laughs are simply normal breed features taken to an extreme. Learning more can be a neat way to practice more thoughtful dog appreciation, looking beyond first impressions and understanding what a dog needs to thrive.
- Chinese Crested
Often associated with the “ugly dog” label because of hairlessness, tufts of fluffy hair, and expressive, sometimes toothy faces, the Chinese Crested is typically lively and people-focused. Hairless varieties can require regular skin care, including protection from sun and dryness. Their look may be unconventional, but their affectionate personality wins hearts quickly. - Xoloitzcuintli (Mexican Hairless Dog)
This breed is famous for its sleek, nearly hairless body and long history. The same hairlessness that makes it stand out visually can mean extra attention to skin health. When well cared for, these dogs can look elegant rather than “ugly,” which is a good reminder that the label says more about trends than about the dog. - Chihuahua mixes
Chihuahuas and Chihuahua mixes often pop up in “ugly dog” conversations because they can have oversized eyes, dramatic ears, and underbites, especially in mixes. They’re also small enough that dental issues can be more visible. Temperament varies widely, but many are bold, funny companions who are deeply devoted to their people. - Wrinkly, droopy-faced breeds
Dogs with lots of loose skin and wrinkles can look comical to some people, but they can be calm, loyal companions with the right training and socialization. Those signature folds also come with real responsibilities, since skin folds can trap moisture and need routine cleaning.
Learning about these looks can open up a bigger conversation: sometimes “ugly” is simply what happens when a dog’s traits are exaggerated through selective breeding, and sometimes it’s the result of age or a condition that changes appearance. Ugliest Dog Day can be a prompt to approach those differences with compassion. A dog with a crooked jaw, missing fur, or a visible disability isn’t a punchline. They’re a living creature who still wants snacks, comfort, and someone to toss the ball.

Major animal welfare groups emphasize that older, disabled, or visually unusual dogs are adopted less often, encouraging people to see these so‑called “imperfect” pets as especially lovable companions.
History of Ugliest Dog Day
Ugliest Dog Day is closely tied to the long-running World’s Ugliest Dog Contest, an event held in Petaluma, California in connection with the Sonoma-Marin Fair. The contest dates back to the 1970s and is widely described as having started as a fundraiser for the Old Adobe Association, a local preservation group. Over time, what began as a quirky attraction grew into a well-known competition with devoted fans, enthusiastic owners, and dogs who often become minor celebrities for their unforgettable faces and big personalities.
The phrase “World’s Ugliest Dog” was trademarked by the fair’s organizers in 2009, a sign of how much the contest had become part of popular culture. While the contest is a specific event with rules and judges, Ugliest Dog Day has evolved as a broader, informal observance inspired by the same idea. It borrows the theme and spreads it beyond a single fairground: celebrate the dogs who would never fit a polished image, and recognize how quickly “ugly” can turn into a term of endearment when a dog is loved.
Underneath the cheeky name, the contest also serves as a playful counterpoint to traditional dog shows. Standard shows reward strict breed standards, immaculate grooming, and precise movement. An “ugliest dog” competition flips that script and spotlights the traits that would normally be faulted, like a snaggletooth grin, a lopsided stance, or a head tilt that never quits. The crowd appeal is obvious, but the staying power comes from the dogs themselves. Many participants are rescues, seniors, mixed breeds, or dogs who look unusual because of a medical condition or old injury. Their owners tend to speak less about looks and more about the dog’s character, habits, and daily joys.
As attention around the contest grew, the message traveled with it. Photos of winners can be funny at first glance, but they often land differently once people learn the backstory: a dog who overcame neglect, a senior who found a second home late in life, or a pet whose strange features are simply part of aging. That shift in perspective is one reason Ugliest Dog Day resonates. It encourages people to look twice, soften quick judgments, and notice what actually makes a dog a good companion.
Because the observance is informal, it has also taken on a life of its own online. Dog owners share “ugly-cute” pictures as badges of honor. Shelters highlight harder-to-place dogs. Friends gently roast their own pets with captions that translate to: “Look at this weirdo. They’re my favorite thing.” When the humor stays affectionate and the dog’s comfort is respected, it can broaden what people consider lovable.
Still, the best version of Ugliest Dog Day keeps the dog’s wellbeing at the center. If a dog’s “ugly” trait is tied to a health issue, the day is a good reminder to prioritize care over comedy. Dental problems, skin conditions, eye issues, and mobility challenges should be handled responsibly, with vet support when needed and daily habits that keep the dog comfortable. Done well, the celebration becomes less about ugliness and more about perspective: a nudge to value personality, resilience, and the simple fact that every dog deserves to be treated kindly.
Facts About Ugliest Dog Day
Hairless “Ugly” Breeds Share a Single Genetic Quirk
Several of the dog breeds most often labeled as “ugly,” such as the Chinese Crested and the Mexican Hairless Dog (Xoloitzcuintli), owe their bare skin and odd dentition to the same dominant mutation in a gene called FOXI3.
Genetic work has shown that this mutation likely arose only once in dogs and then spread through different hairless breeds, which is why coated and hairless pups can appear in the same litter and why hairless dogs so often have missing or oddly shaped teeth.
Wrinkles and Rolls Come With Hidden Health Costs
Heavily wrinkled breeds that sometimes win “ugly dog” contests, such as Neapolitan Mastiffs and Shar Pei–type dogs, are intentionally bred with deep skin folds that can trap moisture and debris.
Veterinary manuals note that these dogs are at high risk of skin fold dermatitis, chronic infections and painful eyelid problems like entropion, which may need lifelong cleaning regimes or surgery to prevent constant irritation and damage to the eyes.
Flat Faces Make Breathing Harder Than Many Owners Realize
Short‑muzzled breeds that often look comically “squashed,” such as Pugs, Bulldogs and Pekingese, are prone to brachycephalic obstructive airway syndrome, where shortened skulls leave too little space for soft tissues and airways.
The British Veterinary Association and other professional bodies warn that noisy breathing, snoring and quick tiring are not cute quirks but clinical signs, and they actively campaign for less extreme faces in these dogs to reduce chronic breathing, eye and overheating problems.
Shelter Dogs With “Less Pretty” Looks Really Do Wait Longer
Studies of shelter populations have found that physical appearance measurably affects how quickly a dog is adopted, with traits like age, size and perceived attractiveness all playing a role.
Research in applied animal welfare science shows that dogs considered less appealing in looks, including older or physically atypical animals, generally experience longer lengths of stay than younger, “cuter” dogs, even when behavior is similar, which is one reason many campaigns spotlight so‑called “underdogs.”
“Ugly” Rescue Dogs Often Become Media Ambassadors
Coverage of the World’s Ugliest Dog Contest repeatedly highlights that many entrants are rescue dogs or have survived illness, neglect or congenital problems, turning their unusual looks into a platform for adoption messaging.
Local news reports describe winners like the French bulldog mix Petunia as shelter rescues whose backstories are used at the fair to draw attention to local rescue groups and to encourage people to adopt dogs that might otherwise be passed over.
Hairless Dogs Have Ancient Roots in the Americas
Although some modern hairless breeds carry exotic names, archaeological finds show that dogs closely resembling today’s Xoloitzcuintli have been depicted in Mexican ceramics and tombs for around 3,000 years.
Pre‑Columbian cultures such as the Aztec and Maya associated these hairless dogs with the god Xolotl and believed they could guide human souls in the afterlife, giving an animal now joked about for its looks a long history as a spiritual companion.
Purebred vs. “Mutt”: Health Is More Complicated Than It Looks
It is common to assume that mixed‑breed “ugly mutts” are always hardier than purebreds, but a large veterinary study of more than 27,000 dogs found a more nuanced picture.
Purebreds did have significantly higher risk for many specific inherited disorders, yet some conditions were more common in mixed‑breed dogs and many showed no difference at all, suggesting that health depends on the particular disorder and breeding practices rather than on pedigree status alone.
