The Lhasa Apso is a non-sporting dog breed originating in Tibet. It has traditionally been used as an interior sentinel. In the early twentieth century, some Tibetan dogs were brought to the United Kingdom by military men returning from the Indian subcontinent. These were of mixed types, similar either to what would become the Lhasa Apso or to what would become Tibetan Terrier; they were collectively known as the "Lhasa Terriers".

Lhasa Apsos are lovable and loyal toward their owners but wary of strangers. Due to their calm and gentle nature, they can get along well with kids. Lhasa Apsos have an average lifespan of 12-14 years. A few of them can live for nearly two decades. A 2004 Kennel Club survey puts the median lifespan of the breed at 14 years 4 months. The UK vet clinic data puts the median at 13.0 years.
