The German Mastiff were a gentle giant dogs. Back to 36 B.C., the image of a dog similar to the Great Dane appeared on Greek money. The German Mastiff is considered as the 'Apollo of dogs'. In 407 A.D., Asiatic people (the Alans) invaded part of Italy and Spain and German Gaul. The Alans brought big mastiff dogs (especially in Germany) with them. They were considered the dogs of royalty and were very high prized and regarded.
