Can somebody tell you as much as they can on the hybreed mix of a great dane and a black lab?

I breed Great Danes and have owned two Dane/Lab mixed. Male and female. I think they are great. They had the better qualities that both breeds offer. They also lived to be 11 and 12 years old. When Danes alone are not expected to live as long. Eight years is a grand old age for a Dane. Keep in mind that all dogs are individuals and have their own personalities, but from my experience there is no better dog than a Dane/Lab.
