my friend breeds beautiful great danes. Harles, Mantles, and blacks mostly. Well, here is a video of her Dam, Ginger, with one of her pups that came out solid white. It was Gingers first litter. The pup goes to his home next week...but here they are playing.
and just to answer the question....he can see and hear fine

It is common for solid white danes to have hearing or vision problems...but he is 100% healthy

aren't they precious???? I want one of her babies SOOOOOOOOO BAD!!!
