Welcome to BPO Writergirl. My name is Ang, and i have a Great Dane named Sanity who's the love of my life, and a Chinook named Hobo, and an evil English Setter named Araby.
I saw you were looking for another Dane mix puppy. PLEASE think about that for awhile. Many people who have Dane puppies think that they're the most perfect wonderful well behaved puppies ever. What it is is that they're spending so much energy growing that thye don't have the gumption to do puppy trouble like things. When the overnight growing stops, usually around 8 months, that's when they do puppy destruction. Cept they're like 80 - 100 pounds by then so it's ALOT of destruction. Most Danes that are brought in for behavior issues are 8-14 months old.
I'm just saying that it would be easier if you waited till your pup was a little more mature before you brought another into your home. Good luck!
