Hi newbie!
What a lovely looking pup!
I had a Great Dane once upon a time. Extremely inteligent she was. She used to try and talk to me, we'd have conversations for hours!
Im afraid I dont know much about training them though as ours was adult when we got her from a rescue and knew pretty much everything.
Hope it goes well tho.
