the dog itself is a Great Dane. Plural (more than one) it is Great Danes.

Yes, both my male and female great danes catch and fetch frisbees.
Great Danes are not natuarlly viscous dogs. They can be trained for many jobs, including guarding.
Great Danes are believed to be originated in Germany by the Alans from Mastiff's and probably wolf hounds.
