The Lài dog is a medium-sized landrace from the mountains of northern Vietnam, especially the upland country along the Mã River west of Thanh Hóa. It has a long, sturdy body, a triangular head, amber or reddish eyes and a double coat that can be short or long. It is counted among Vietnam's four traditional national dogs, but it is critically endangered and very rarely seen outside its home area.

Typical adult ranges. Males are often at the top of the range and females at the bottom. Most reach adult size by around 12 months.
Lifespan
12–16 years
Most Lài dogs live 12–16 years. Like other medium dogs, they're usually considered senior from about 8, when twice-yearly vet checks help catch problems early. Keeping them lean is one of the most effective things you can do for a long life. How old is that in human years?
Temperament
Lài dogs are known as clever, quick and devoted to their own people, and they can be fiercely protective. They are typically aloof with strangers, which makes them good watchdogs but means they need careful introductions. Many bond so strongly with their owners that rehoming an adult is difficult.

Exercise
90–120 min a dayBred as farm and hunting dogs, they have great stamina and need plenty of daily activity and room to roam safely. They are agile enough to climb and swim.
Grooming & shedding
The weather-resistant double coat benefits from a weekly brush, more often when it is moulting.
Health
Their protective streak means early, thorough socialisation is important. Traditionally they were allowed to roam, and cross-breeding with other dogs is now the main threat to the landrace, so anyone acquiring one should do so through conservation-minded breeders. Very little veterinary research has been done on the breed.
The breed can be prone to
- Considered robust; no breed-specific problems are documented
Health tests to ask a breeder about
- General veterinary check before breeding

History
Dogs of this type are thought to have reached Vietnam from southern China several thousand years ago, and dog images appear on Bronze Age Đông Sơn artefacts. Vietnamese historical writing credits the dogs with serving Lê Lợi's forces in the Lam Sơn uprising of the early 15th century, after which they stayed with soldiers guarding the northern borderlands. Today only a few hundred pure dogs are believed to remain, and conservation breeding efforts are under way.
