That is really a matter of opinion. If you like dogs, then yes, you will find them cute. If you don't, you won't. I have great danes and I find them cute, but only as cute as other dogs such as labs.
the dog itself is a Great Dane. Plural (more than one) it is Great Danes.
no because, the great danes are much bigger than the poodles
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.
Great danes like all dogs do have backbones.
