Moscow Watchdog
This dog breed was really meant to be a watch dog. Don’t be fooled by its tame look. The truth is that it can be very dangerous. It was originally created by brreding the vicious Caucasian shepherd with the large Saint Bernard. As a result, the dog is stunningly huge and very strong. The first breeds though were not that aggressive. As time went by, they were able to create dogs with better mental and physical attributes, making them even scarier.
