The Cavanese is a hybrid dog breed, a cross between the Cavalier King Charles Spaniel and the Havanese. These dogs are small, affectionate, and have a gentle temperament. Known for their silky coats and expressive eyes, they thrive as family companions and are adaptable to various living environments.

The Cavanese is not a scientifically recognized animal species. It appears to be a name sometimes used to refer to a hybrid dog breed, a mix between the Cavalier King Charles Spaniel and the Havanese. As a hybrid breed, it does not have a wild native region but is instead bred by humans.

As domesticated pets, Cavanese dogs are typically found in human environments such as homes and urban areas. They thrive in conditions where they receive adequate care, regular exercise, and social interaction.

The ecological niche of the Cavanese is that of a companion animal, providing emotional support and companionship to humans. They do not occupy a traditional ecological niche in the wild.
