Getting a Great Dane Tomorrow....?

hi everyone so me and my husband our picking up our great dane puppy tomorrow as you can imagine were very excited, but was just hoping somebody could give us some hints we have Deon lots of research on the giant breed and have 2 dogs already so we know how much time and work they require. He is not a christmas puppy! So if you could give a few pointers that would be fab. Also what names would be good? i love tiny lol or marmaduke but my husbands not sold. Thanks everyone and merry christmas x
