well, it will be a larger sized dog because of the dane, it also depends on the colors of both of the breeds. It may like to swim because of the blood lines of the chesapeake bay.
We have a Great Dane and a Golden Retriever. They love to play and run in the yard. They "body slam" when they play like football players in the field.
English Mastiff
Iwao Takamoto created Scooby Doo to look like a Great Dane .
There is unfortunately no webkinz great Dane......
Some types of Great Dane have spots, making them appear like oversized Dalmatians. An example is the Harlequin Great Dane.
Maybe a trip to the vet is called for?
See related link.
Great Danes have very thin coats, so they do not like cold weather. If it's comfortable for a person, it's comfortable for a Great Dane. In cold weather they really do need a coat to help them keep warm, just like a person.
He's a Great Dane, like Marmaduke and Astro of The Jetsons.
Height is same like great dane, weight is half of that.
Great danes like all dogs do have backbones.
It looks a little like a golden retriever, except it is smaller and a little longer looking. Most have white on its chest and legs. They are great dogs!
