The temperament has been one of the most attractive aspects of the breed since it was first established in the 1920's. They are amiable and affectionate family dogs, sensitive to their owners and gentle with older children. As is fitting a dog formerly used as a watch dog, they tend to be reserved around strangers, but should never be aggressive nor shy with them.
Suitable for apartment living, the Tibetan is still an energetic and surprisingly strong dog, and needs regular exercise. Their energy level and intelligence is well suited for dog sports such as agility. They are steadfast, determined, and clever, which can lead to them being stubborn. Some dogs of this breed can often be jealous, which can make it hard to live with another pet.(Wikipedia)
