The Care-Tzu is a small, affectionate hybrid dog breed, a cross between a Shih Tzu and a Cairn Terrier. It typically features a fluffy coat, expressive eyes, and a playful demeanor. Known for its sociable nature, the Care-Tzu thrives in family environments and adapts well to apartment living.

The Care-Tzu is not a wild animal species but a domesticated dog breed, resulting from a cross between the Shih Tzu and the Cairn Terrier. As such, it does not have a native region in the wild. Both parent breeds originate from different parts of the world: the Shih Tzu is originally from China, and the Cairn Terrier hails from Scotland. Therefore, the Care-Tzu does not have a natural geographical distribution.

As a domesticated dog breed, the Care-Tzu typically inhabits environments suitable for human dwellings. They can adapt to a variety of living conditions, including apartments and houses with yards, as long as they receive adequate care and exercise.

The Care-Tzu's ecological niche is that of a companion animal, providing companionship and fulfilling roles in human households. They do not occupy any ecological niche in the wild, as they are bred and maintained by humans for domestic purposes.
