What counts as a “small” breed
There is no official “small” category. The FCI recognises 364 breeds and organises them into ten groups by function and type, not size. The American Kennel Club uses seven groups; its Toy Group comes closest to a size category, but it still mixes breeds of very different origins. In practice, owners and the pet trade call breeds “small” when adults weigh up to about 10 kg. It is a useful reference for space and handling, not a hard limit.
Popular small breeds and how they are classified
| Breed | FCI group | AKC group | Practical note |
|---|---|---|---|
| Yorkshire Terrier | 3 — Terriers | Toy | Long coat needs frequent brushing |
| Shih Tzu | 9 — Companion and Toy | Toy | Coat and eyes need regular hygiene |
| Poodle (Toy/Miniature) | 9 — Companion and Toy | Toy (Toy Poodle) / Non-Sporting | Coat keeps growing and needs regular clipping |
| Maltese | 9 — Companion and Toy | Toy | Long white coat, daily care |
| Pug | 9 — Companion and Toy | Toy | Brachycephalic: watch heat and breathing |
| French Bulldog | 9 — Companion and Toy | Non-Sporting | Brachycephalic: avoid exertion in heat |
| Pomeranian (German Spitz, dwarf) | 5 — Spitz and primitive | Toy | Thick double coat, constant brushing |
Notice that “small” does not mean “companion breed”: the Yorkshire is a terrier under the FCI, and the Pomeranian is a spitz. Any list of “most popular” small breeds varies by country, source and year; treat it as a reference, not a census.
Care that small size calls for
- Feeding: amount and type of food vary with age, weight and health. Don’t guess — ask your veterinarian.
- Cold: very small dogs lose heat faster and may need protection on cold days.
- Falls and children: a delicate frame needs care with jumps, being stepped on and rough play.
- Flat-faced breeds: Pugs and French Bulldogs need extra care with heat and exertion; any breathing sign is a matter for the vet.
- Routine health care: vaccination, parasite control and neutering should be planned with a veterinarian.
Small does not mean easy
Small size solves part of the space problem, but it does not remove the need for walks, stimulation and training. Many small dogs are full of energy and pick up unwanted habits without a routine. Before choosing on looks, think about the time you have, who lives with you and how much daily care the breed’s coat and health will demand. Mixed-breed dogs from shelters come in small sizes too and make excellent companions. Breed profiles: Shih Tzu, Maltese and Chow Chow.
Frequently asked questions
Is a small dog breed better for an apartment?
Small size helps with space, but it is not enough. Small dogs also need daily walks, stimulation and training. Weigh the time you have and the breed's routine before deciding; size is only one factor.
Do small breeds live longer than large breeds?
Smaller dogs are often said to live longer, but lifespan varies a lot with the individual, genetics and care, and there is no fixed rule by size. Ask your veterinarian about longevity and health for your own dog.
Do Pugs and French Bulldogs need special care?
Yes. They are brachycephalic (flat-faced) breeds and need extra attention to heat and physical effort. Any breathing sign should be assessed by a veterinarian, who can advise on how to manage it.
Where can I check what a small breed is really like?
In the official breed standard published by the FCI or by your national kennel club, such as the AKC in the United States. It describes the size, structure and original function of each breed, instead of relying on loose descriptions online.
