The Moscow Watchdog measures 25 to 27 inches at the withers and weighs from 110 to 150 pounds.  Their coloring is incredibly close to that of a Saint Bernard; red and white with a black mask.  I have also noticed that the muzzle often has several black spots; many seem to have spotting of red, orange, or brown on their legs.  The spotting on the coat probably comes from the Russian Spotted Hound.  
The Moscow Watchdog has a massive head, triangular ears that lie close to the head, with medium sized round eyes.  My observation has been that the ears are a bit smaller than a typical Saint Bernard, also the eyes of a Saint Bernard are diamond in shape.  Some photos I have seen, the muzzle seems to be a bit longer than a Saint Bernard.
It is easy to see how people can mistake a Moscow Watchdog for a Saint Bernard; however if you take a closer look you will see the differences.  The Moscow Watchdog is also much more active than a Saint Bernard.
