Id suggest a female as well, just because the male dobermans tend not to like other male dogs. The issue wouldnt be whether or not your golden would get along. Male dobes arent male friendly. Aside from that, I have always felt females are easier to manage with their gender issues. If you dont curb certain male instincts in time they can be a real pain. This may not hold true for all males but when we had our chocolate lab we had one hell of a time keeping him from lifting his leg on everything, especially when he got into unexplored territory.
