The best small dog breeds are not the ones that ask least of you. They are the ones whose demands match your actual week. Three weeks on Vancouver Island with three Bichon Frises taught us that faster than any breed profile could — same breed, same house, same fluffy coat, three genuinely different dogs.
Between us, Jackie and I have housesat more than twenty pets across Australia, Canada, the UK and Mexico, and the little dogs taught us most: Apple the Shih Tzu for five weeks, Ruby the dachshund in England, a pair of cavoodles in Australia. Cesar is a conservation biologist, so we ask why a dog does something rather than just noting that it does.
Below are fifteen small dog breeds worth meeting, with the numbers that decide things: adult weight, exercise minutes, grooming cadence, the health conditions large veterinary datasets flag, and whether each is a sensible first dog.
1. Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is the gentlest small breed on this list and the one with the heaviest health caveat. They weigh 13 to 18 lbs, adapt well to small spaces, and want 30 to 45 minutes of moderate exercise. Weekly brushing keeps the feathered coat and floppy ears clear. They are the definition of a velcro dog — bred purely for human companionship, not work — which makes them excellent family dogs with younger kids and other pets, and poor candidates for long days alone. The catch is mitral valve disease: roughly half have a heart murmur by five, nearly all survivors by ten. Buy only from breeding dogs with cardiologist-graded parents.
2. Shih Tzu
Shih Tzus are content with apartment living and among the best small dogs to have in a flat. They weigh 9 to 16 lbs, need only 20 to 30 minutes of walking, and are famously tolerant family dogs with young children. We had Apple, a very small Shih Tzu, for five weeks alongside two fox-terrier types — long enough to watch a dog stop performing and simply live with you. The grooming is the real cost. That floor-length silky coat needs daily brushing or a clip every four to six weeks; skip either and you get mats against the skin. The shortened muzzle also means heat intolerance. Expect 12 to 14 years.
3. Bichon Frise
Bichon Frises are cheerful, gentle, and one of the easiest small breeds to train, weighing 10 to 18 lbs and thriving in apartments on 30 to 45 minutes of daily walks and playtime. The curly double coat needs daily brushing and a professional trim monthly, that fluffy coat is a maintenance contract, not a decoration.
Our three on Vancouver Island had markedly different personalities, which is less an anecdote than a demonstration. Morrill and colleagues surveyed 18,385 dogs and found breed explains only about 9% of behavioural variation between individuals. Three Bichons in one house is that statistic with legs.
4. Miniature Dachshund
Miniature Dachshunds are the longest-lived small dog in UK veterinary data, with a median life expectancy of 14.0 years. They weigh 8 to 11 lbs, want 45 to 60 minutes daily, and a smooth coat needs little more than occasional brushing. Ruby, the dachshund we sat in England, went to the beach with us most days and would not swim — not stubbornness, but physics. Wiener dogs were originally bred to go down badger setts, so the chondrodystrophic build gives them almost no paddling leverage. That same build carries real risk of intervertebral disc disease. Ban the sofa jumps, keep them lean, and read our full dachshund guide before committing. Barking tendencies: high.
5. Miniature Poodle
Miniature Poodles are the smartest of the small dog breeds and the most likely to outwit an underprepared owner. At 10 to 15 lbs they need 45 to 60 minutes of exercise plus genuine mental stimulation — puzzle work, training games, dog sports. Bored poodles invent hobbies you won’t enjoy. The curly coat requires professional grooming every four to six weeks, non-negotiable. Toy poodles carry the highest recorded dental risk of any breed at nearly four times average. Poodle crosses dominate the mixed breeds market for a reason; the cavoodles we sat in Australia were the obvious proof, and we’ve written up cavoodles and cavapoos separately.
6. Jack Russell Terrier
Jack Russell Terriers need 60 to 90 minutes of exercise daily and are the least apartment-suited dog here. These are active dogs originally bred to bolt foxes from earth, and that engine did not switch off when they moved indoors. At 13 to 17 lbs with a smooth or wiry coat needing only weekly brushing, they are minimal grooming and maximal management. The two fox-terrier types who lived with Apple during our five-week sit ran on a completely different clock. Terrier breeds suit an active family with older children and no small pets; they are honestly not a first dog. Lifespan is a robust 13 to 16 years.
7. Miniature Schnauzer
Miniature Schnauzers are the best small dog breed for people who want terrier character with an off switch. They weigh 11 to 20 lbs, have moderate exercise needs of 45 to 60 minutes, and the wiry double coat wants weekly brushing plus hand-stripping or clipping every six to eight weeks, with occasional trimming around the beard. They shed very little. Even tempered with older children, alert without being frantic, and eager to please enough to be easy to train, they’re one of the few terriers we’d hand a first-time owner — a genuinely low-drama family pet. Watch for hyperlipidaemia and pancreatitis — this breed genuinely cannot handle table scraps. Our full schnauzer breakdown goes deeper.
8. Yorkshire Terrier
Yorkshire Terriers require daily brushing to maintain their long, silky coat, or a short clip that most pet parents eventually choose. At 4 to 7 lbs they’re true toy breeds: 30 minutes of walking is plenty and apartment living suits them. The health data is the caution. In a VetCompass study of 210,824 dogs, Yorkshire Terriers showed 5.4% prevalence of luxating patella (over five times average) and dogs under 5 lbs risk hypoglycaemia. They bond hard, bark readily, and can be prickly with other dogs unless socialised early. Typical lifespan 12 to 15 years.
9. Maltese
Maltese dogs shed very little and need regular grooming to prevent tear stains and matting — frequent brushing of that silky coat plus face-washing most days. At 4 to 7 lbs they want 20 to 30 minutes of gentle exercise and are among the most apartment-adapted little dogs going. On the hypoallergenic claim attached to Maltese, Shih Tzus, poodles and Lhasa Apsos: Vredegoor and colleagues measured the major dog allergen Can f 1 in hair and homes and found no support for calling any breed hypoallergenic. Low shedding is real; allergen-free is marketing. Best with older children, given how easily a 5 lb dog is hurt.
10. Havanese
Havanese are playful, responsive to training, and the small breed we’d recommend most often to first time pet parents. Cuba’s national dog weighs 7 to 13 lbs, needs about 30 minutes daily, and asks for regular brushing three or four times a week, lower grooming needs than the Maltese or Bichon for a similar look. They’re another velcro dog, genuinely good with younger kids, other dogs and other pets, and quiet by toy-breed standards. Apartment living suits them perfectly. Expect 14 or more years, with patellar luxation and eye conditions the main things to screen.
11. French Bulldog
French Bulldogs are ideal for apartments due to low exercise needs: 20 to 30 minutes, and only in cool hours. At 16 to 28 lbs with a short coat needing weekly brushing, they are minimal grooming and maximum veterinary attention. Liu and colleagues assessed 604 brachycephalic dogs and found 58.9% of French Bulldogs had clinically significant airway obstruction. UK life expectancy is 9.8 years — the shortest of 155 breeds analysed. We like Frenchies enormously and we would still tell you to look at a Boston Terrier first, or insist on a BOAS-graded litter.
12. Pug
Pugs weigh 14 to 18 lbs and adapt well to apartments, needing daily walks or playtime of 20 to 30 minutes to stay healthy, never in heat. Their double coat sheds far more than people expect; weekly brushing barely contains it, and pale fur turns up on everything you own. Pugs are affectionate, comic and adaptable to various living situations, and excellent with children. But 64.6% show clinically significant BOAS, median lifespan is 11.6 years, and obesity in small dogs compounds all of it. A lean, moderately-muzzled pug from a health-testing breeder is a different animal to a supermarket one.
13. Boston Terrier
Boston Terriers are the flat-faced breed we’d actually recommend, because their muzzle is meaningfully longer than a pug’s. Often called the American Gentleman, they weigh 12 to 25 lbs, need 30 to 45 minutes daily, and their short smooth coat asks for occasional brushing and nothing else. They are even tempered, sturdy enough for active family life with younger kids, and generally sociable with other dogs. Prominent eyes mean injury and ulcer risk — the trade-off for that face. Lifespan runs 11 to 13 years. For a first dog in an apartment, they’re one of the strongest picks here.
14. Chihuahua
Chihuahuas are highly alert, fiercely loyal, energetic, and require protection from cold weather — a 3 to 6 lb dog with a smooth coat has almost no thermal buffer, which is basic surface-area-to-volume biology, not fussiness. They need 20 to 30 minutes of walking, suit apartment living, and the smooth coat needs occasional brushing only. Prevalence of luxating patella is 4.9%, nearly six times the average dog. They can live 15 years or more. The reputation for snappiness is mostly a training failure: tiny dogs get carried instead of taught. Small dogs benefit from the same obedience training and socialization as larger dogs.
15. West Highland White Terrier
West Highland White Terriers are the small breed with the best ratio of character to size, weighing 15 to 20 lbs and needing 45 to 60 minutes daily. The harsh white double coat wants weekly brushing and stripping or trimming every eight weeks; it sheds little but demands regular grooming. Like the Cairn Terrier and Scottish Terrier, they were bred to kill vermin in Highland rock — hence the digging, the barking tendencies, and the conviction that they are large dogs. Atopic dermatitis is the signature problem. Best with older children and a second-time owner; fine in an apartment given real walks.
Frequently Asked Questions
The Cavalier King Charles Spaniel is the calmest small dog breed, followed closely by the Havanese and Shih Tzu — all three were bred purely as companions rather than workers. But temper that: breed accounts for only about 9% of behavioural variation between individuals, so the calmest pup in a litter of Jack Russells may out-settle the liveliest Cavalier. Meet the adult dogs before choosing.
The best small breed dogs by vet consensus are those without extreme conformation: Miniature Schnauzers, Havanese, Bichon Frises, Miniature Poodles, Boston Terriers and Miniature Dachshunds from health-tested lines. Stretch the definition and Cocker Spaniels, needing 45 to 60 minutes of active exercise daily, and Beagles both thrive in busy family environments. Small dogs develop dental disease earlier than large breeds — under 10 kg carries roughly three times the risk — so the best small dog to have is one whose teeth you brush daily.
The French Bulldog is currently the most wanted small dog breed in the US, UK and Australia, with Cavalier King Charles Spaniels, Dachshunds and poodle crosses close behind. Popularity is not a recommendation: Frenchies have the shortest life expectancy of 155 UK breeds analysed, 9.8 years. Across toy dog breeds and little dog breeds alike, the most popular small dog breeds and the best small dogs to own are not the same list.
Which is the best small dog breed for you?
Size tells you how much floor a dog needs and almost nothing about how much life it needs. A Jack Russell in a two-bedroom apartment with 90 minutes of proper work is happier than a Cavalier in a house with nobody home. Match the exercise minutes and grooming cadence to your real week, not your aspirational one.
