A Chinese dog counted among the oldest breeds, known for its lion-like mane, blue-black tongue and dignified bearing. Calm, clean and loyal to its family, but aloof with strangers. Inward-rolling eyelids (entropion) and poor heat tolerance are the breed's two biggest health issues.

The Chow Chow is a spitz dog known in China for more than 2,000 years and counted among the oldest breeds in the world. With its lion-like mane around the head and shoulders, blue-black tongue and distinctive "scowling" expression, it looks like no other dog. At home it's calm, clean and loyal to its family, and it stays reserved with strangers. However, some of the features that create the breed's look also affect its health: inward-rolling eyelids (entropion) and struggling in the heat are very common in this breed. We've put this page together from breed registry standards, animal welfare resources and scientific studies.
The FCI standard describes the Chow Chow as a quiet dog and a good guard: independent and loyal, yet aloof. The AKC also presents it as dignified, serious-minded and aloof: a well-socialized Chow is never fierce or intractable, but always refined and dignified, reserved with strangers and eternally loyal to its loved ones.
In the AKC's breed trait chart, the Chow is rated at the top of the scale for watchdog instincts and at the bottom for barking, so it's usually a quiet dog. Its scores for getting along with other dogs and openness to strangers are on the low side.
Every dog is an individual. Breed traits describe general tendencies; how well a puppy was socialized, its training, its daily life and its health shape its personality as much as its breed.
The Chow Chow suits people who want a calm home life, respect their dog's independence and can make time for regular coat care and eye checks. According to the AKC, it has no special exercise needs and adapts well to city life.
| Situation | Good fit? |
|---|---|
| Apartment | Possible; the AKC says it takes to city life, while the Royal Kennel Club recommends a large house |
| Family with kids | With supervision; the AKC rates it as moderate with children |
| Other dogs | Needs care; the AKC rates it low with other dogs |
| Homes with frequent visitors | Reserved and protective; early socialization is a must |
| Hot climates | Hard; the AKC stresses that it doesn't tolerate high heat or humidity well |
| First-time dog owners | Possible, but learning about eye health and coat care is a must |
| A calm lifestyle | Excellent; it isn't an overly active dog |
If you have children at home, a quiet corner where the dog can retreat and clear rules are essential. Our article on kids and dogs offers step-by-step tips.
According to the FCI, the Chow's ancestry traces back to China, where it was kept as a guard dog and also used for hunting. Known in China for more than 2,000 years, the breed is thought to be related to Nordic-type spitz dogs, with something of the mastiff in it as well. The AKC notes that Chows appear in artifacts from the Han Dynasty (around 206 BC) and relays that a Tang Dynasty emperor was said to have kept thousands of Chows. Over its long history, it served as a companion to nobles as well as a guard, hauler and hunter.
Because of China's closed-door policy, Chows only began to appear in other countries around 1800. According to the Royal Kennel Club, East India Company traders brought two Chows to Britain in 1780; Queen Victoria's Chow sparked public interest, and the Kennel Club recognized the breed in 1894. The AKC relays a popular explanation for the name: "chow chow" was an 18th-century expression for the miscellaneous, unlisted items in British trading ships' cargo, a way of saying "etcetera." Today the FCI places the breed in Group 5 among the Asian spitz breeds.
According to the FCI, the Chow is an active, compact, short-coupled, well-balanced and lion-like dog that carries its tail over its back. The bluish-black tongue is characteristic of the breed. The small, thick ears tilt forward, giving the breed's typical "scowling" expression; the standard says this scowl should never come from loose, wrinkled skin on the head. Its short-striding gait swings like a pendulum, but per the standard the dog must always be able to move freely without any sign of distress.
According to the AKC, both rough- and smooth-coated Chows have a profuse double coat that needs regular grooming: thorough brushing at least twice a week and a monthly bath keep the skin and coat healthy. The Royal Kennel Club recommends daily grooming. The puppy coat and the hair around the head can mat badly if not groomed regularly, so mats need to be worked out and the undercoat brushed down to the skin. Drying thoroughly with a cool-air dryer after a bath is recommended.
In a 2020 UK study by Hall and colleagues, the Chow Chow had the highest risk of heat-related illness (heatstroke) of any breed studied: about 16 times the odds of Labradors. The authors link this to the breed's very thick coat, but note that the small sample size gives the estimate a wide margin of uncertainty. The AKC also stresses that Chows don't tolerate high heat or humidity well and should not exercise during the hot part of the day.

According to the AKC, the Chow is active and alert but has moderate exercise needs: daily walks and gentle play with toys are enough, and rough play or high-impact exercise is not recommended. The AKC suggests moderate-paced walks four or more times a day. The Royal Kennel Club also recommends up to an hour of exercise a day.
For training, the AKC recommends early socialization, puppy classes, and patient, positive, consistent reinforcement. Chows are very intelligent but can be stubborn, and harsh methods should be avoided to build a trusting relationship. Patience, praise and regular practice are the best tools.
The AKC says good-quality commercial dry or wet foods suit the Chow, and recommends checking the skin for irritation or allergy signs even if the food hasn't changed, since manufacturers sometimes change formulas. Treats can cause allergy and digestive problems too. Avoid table scraps, especially cooked bones and fatty foods.
According to the AKC, Chows can have eyelid entropion, hip and elbow dysplasia, allergies and thyroid problems, and these risks can be reduced through health screening and responsible breeding. The Royal Kennel Club lists an eye exam and hip and elbow screening as minimum requirements for breeding, and places the breed in Category 2 of its Breed Watch list (breeds with points of concern). The information below is for awareness only; ask your vet about diagnosis and treatment.
Entropion means the eyelid rolls inward, so the eyelashes and eyelid skin constantly rub against the surface of the eye. According to UFAW, this causes irritation, pain and, over time, possible permanent damage to the eye; without treatment, most affected dogs live with lifelong pain. In most breeds entropion comes from loose eyelids, but in the Chow it's usually caused by a narrow eye opening, and excess skin on the brow and cheeks can add to the problem. That's why corrective surgery can be harder in Chows and may need more than one operation.
In a 2025 study by O'Neill and colleagues, based on the records of more than 2 million dogs in the UK, the one-year prevalence of entropion in Chow Chows was about 9.3%, and their odds of entropion were about 53 times those of mixed-breed dogs. UFAW advises checking whether a puppy keeps its eyes fully open and whether it blinks a lot or has discharge, and avoiding puppies whose parent has or had entropion. The FCI standard also requires eyes free from entropion.
The AKC's recommended tests include hip, elbow, patella, eye and thyroid evaluations. Ask for the parents' results when you look for a puppy.
In a 2024 study by McMillan and colleagues that analyzed records of more than 584,000 dogs in the UK, the Chow Chow had a median lifespan of 12.1 years (confidence interval 11.7–12.5), almost the same as mixed-breed dogs (12 years). The Royal Kennel Club, however, lists the breed's lifespan as "under 10 years," and the AKC gives 8–12 years. Differences in data sources and methods may explain part of this gap.
Early treatment of eye problems, an ideal weight, protection from heat and regular vet checkups are the most concrete ways to improve both lifespan and quality of life in this breed.
The blue-black tongue is one of the breed's best-known features, and the FCI standard lists it as characteristic of the breed. Per the standard, the ideal is a solid black mouth, including the roof and lips; blues and fawns may show some lighter shading.
It needs care. In a 2020 UK study, the Chow Chow had the highest risk of heatstroke of any breed, and the AKC says the breed doesn't tolerate heat and humidity well. In summer, walk early in the morning and in the evening, provide a cool room and plenty of water during the day, and never leave it in a car.
UFAW suggests checking whether the puppy keeps its eyes fully open, blinks constantly or has discharge. Some puppies with mild entropion may grow out of it, but there's no way to predict which ones will. Ask for a vet exam to be sure.
It's very loyal to its family and usually calm at home. But it's aloof with strangers, independent and doesn't welcome petting from everyone, so it always needs supervision and clear rules around young children.
The FCI standard doesn't accept trimming that alters the dog's natural outline (except tidying the feet), though that mainly matters for shows. PDSA, on the other hand, suggests considering a clip for heavy-coated dogs in warm months. According to the University of Minnesota's dermatology handbook, hair can fail to grow back fully for months, sometimes 1–2 years, after clipping in dense-coated breeds, so make the call with your vet; thorough, regular brushing is a must either way.
