Moscow Water Dogs were bred in Krasnaya Zvezda, Belarus, by interbreeding Newfoundland males with East European Shepherd and Caucasian Ovcharka females, and by mating the offspring with each other. They were developed as a water rescue/lifesaving dog, but according to O. Krasnovskaya, "That was not a good idea as [they] were not willing to save drowning people, but mostly were looking to bite them so this breed was never developed".
excerpt from wikipedia article I was reading... I can't stop laughing at the mental image of a dog swimming up to someone and biting them!
I was drowning, and I was almost able to save myself until this dog swam over and attacked me!
