I'm assuming that you are reffering to what colors should be bred to a blue dane. The AKC breed standard states that a blue great dane may be bred with one that is a blue or a black.
The female comes into heat and then is able to be bred. The male will mount the female and breed her. It is just like any other dog.
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.
