The Chi Apso is a hybrid breed, a cross between a Chihuahua and a Lhasa Apso. This small dog is known for its lively and affectionate nature, with a distinct appearance featuring a long, flowing coat and expressive eyes. Chi Apsos are adaptable and thrive in various environments, from apartments to larger homes.

The Chi Apso is not a wild animal species but a designer dog breed, resulting from the crossbreeding of a Chihuahua and a Lhasa Apso. As such, it does not have a native region in the traditional sense like a wild species would. It is primarily bred in various parts of the world, particularly in regions with a high demand for designer dogs, such as North America and Europe.

As a domesticated dog breed, the Chi Apso is adaptable to living in human environments. It typically resides in household settings, ranging from urban apartments to rural homes. The breed thrives in environments where it has access to human companionship, adequate space for exercise, and protection from extreme weather conditions.

The Chi Apso's ecological niche is that of a companion animal, providing emotional support and companionship to humans. It does not occupy a specific ecological niche in the wild, as it is a product of selective breeding for specific traits desired in household pets.
