The Comfort Retriever, also known as the Miniature Golden Retriever, is a hybrid dog breed. It combines the friendly demeanor of the Golden Retriever with the compact size of smaller breeds like the Poodle or Cocker Spaniel. They are known for their affectionate nature, intelligence, and adaptability to various living environments.

The Comfort Retriever is not a wild animal species but a designer dog breed, specifically a cross between a Golden Retriever and a Cavalier King Charles Spaniel. As such, it does not have a natural 'native region' in the wild. These dogs are bred in various parts of the world, primarily in North America and Europe, where they are popular as companion animals.

Comfort Retrievers thrive in domestic environments where they have access to both indoor comfort and outdoor spaces. They are adaptable to a variety of living conditions, from apartments to houses with yards, provided they receive adequate exercise and mental stimulation.

As domesticated animals, Comfort Retrievers occupy the ecological niche of human companions. They are bred for their friendly nature, intelligence, and trainability, making them suitable for families, therapy work, and as general pets. They do not have a specific ecological niche in the wild.
