As most of you know I'm in the market for a new puppy and I'm spending time researching breeders and breeds. There is a huge distinction between the dobie AKC and UKC alone. The european stock has the larger bone structure, solid black eyes and I think the european back slopes but not the american line on the doberman breed. As for the temperament distinction the american are more cuddly and the euro wants to work all day. Both are highly active and a blast to have in your life if you like that sort of thing.
