The Lhasa Apso comes originally from Tibet, where it worked historically as a watch dog. Today, these small dogs are well-loved companions and also excel in competitive agility. Their bodies are longer than they are tall, and they are known for their distinctive, long, flowing hair. Lhasa Apsos are deeply devoted to their families and are good with children. Because these dogs don't shed much, they may be a good choice for those with allergies.
