Over the years I've had four rescued dogs, three of which have been dobermans. I've been a long time fan of this breed but would encourage anyone looking for a new best friend to research their local animal rescue centers and groups.
As for dobermans they are very smart, oddly enough needy, love attention of their family and can do great with their own young kids but can be very defensive against other young kids. That may be a plus and a minus as friends may need to play in areas unaccessible by the doberman. Each can be different about what they will and won't accept but all demand a strong willed alphas or they will dominate you.
Hope this helps and if I can try to answer any questions feel free to ask.
