The Moscow Water Dog, also known as the Moscow Diver, is a now-extinct breed that originated in Russia. It was developed in the 1950s and 1960s by the Russian military for use as a rescue dog in water. The breed was primarily found in areas around Moscow, Russia.

The Moscow Water Dog was bred to operate in cold water and harsh conditions typical of the Russian climate. This includes cold temperatures, icy waters, and rugged terrains. The breed was expected to perform in environments near rivers and lakes, particularly in emergency and rescue scenarios.

The Moscow Water Dog was intended to serve as a water rescue and retrieval dog, fulfilling roles similar to those of the Newfoundland and other water-rescue breeds. Its ecological niche was closely tied to aquatic environments where it could utilize its strength and swimming ability.
