from the few people I've known with dobes, they've all seemed a lot more mellow than that. I did a lot of research on them a while back because I really liked (and still do like) them. I think the Dobe Club of America says as long as you train them and give them all the companionship they need, they are complete sweathearts with anyone. My sister's friend has one and he roams off leash in their yard and comes up to anyone off the street and licks their face! I just love their suspended, springy trot! Some friends a while back had two dobes, both males and they got along wonderfully, but that is just my experience, I've never owned one.
