Doberman Pinschers are not the smartest dogs around although they're pretty smart and can be trained to do a lot of great tricks and perform certain tasks.
Doberman Pinschers are also great guard dogs and I used to have one that wouldn't even let my mom into my house when she came over.
I had to take the Doberman Pinsher outside while my mom was there and it wasn't just her it was other people who came over that the dog didn't know.
The Doberman Pinschers are wonderful dogs that are friendly once they get to know you but they're also very protective.
My Doberman Pinscher would also get his leash for me and bring it to me to let me know he wanted outside or to go for a walk.
