Why are chesapeake bay retrievers named retrievers?

Chesapeake Bay Retrievers are named "retrievers" because of their primary purpose: retrieving waterfowl from the water.

The breed was developed specifically to work with hunters in the harsh conditions of the Chesapeake Bay. Their dense, oil-resistant coat, strong swimming abilities, and natural retrieving instincts made them ideal for retrieving ducks and geese from the cold, often rough waters of the bay.

The term "retriever" applies to any dog breed developed for the specific task of retrieving game, particularly waterfowl.
