Many landlords will not allow intimidating looking guard dog breeds and big game hunting breeds to live on their properties.
The Moscow Watchdog, a Russian guard dog, crossbreed of the Caucasian Ovcharka and St. The Great Dane is a molosser, mixed with unknown sighthounds, to improve its agility and speed in boar hunting.
The Great Dane looks similar to the Broholmer, a nearly extinct Danish Mastiff, so the Great Dane could actually truly be a Great Dane.
Current Great Danes are considered to be less ferocious than the medieval specimens that hunted wild boar.
The Fila, Dogo and Tosa are banned from the UK and Pitbulls must be microchipped, neutered and muzzled.
The Canary dog or Presa Canario, is considered to be a natural fighting dog and should be carefully watched around other dogs.
Both guard dogs and watchdogs bark loudly to alert their owners of an intruder's presence and to scare away the intruder.
