Hi, Its a very good question to ask. I would take your Doberman to play with a small pup first. You want to make sure they get along well. We have Princess our Yorkie, Poncho our Chihuahua, and Mandy our Rottweiler. They are all best friends. Big & Small can get along. but you need to make sure they do before ever leaving them alone. I do have a lot of friends with Big & Small, and have had no problems. But I also heard stories about some that didn't get along.
I treat all ours the same, they all live inside, get lots of One on One. And if Mandy wants up on my lap, well that's where she goes. (my poor legs!!! LOL)
Again, I would take him to see a small pup, and if he's game, I'd say go for it.
