Hi and Welcome!! 
I'm a first time Doberman owner and I couldn't have picked a better breed IMO. Bruno is also my first dog (other then growing up). But like Lexus said they take alot of time and dedication. I'm a stay at home mom so Bruno is ALWAYS with someone. Rarely, if at all left at home. He's always in the van no matter where we go
He thinks he's a 54lb lap dog haha.
Good Luck with the search
