Never put a male Dobe with another male in the same house! Females generally tend to get along just fine though, just aslong as you don't have two dominant females. They're very, very guardy and protective. Much moreso than any Rottweiler I've ever had. Dobermans are always ready for action! Show Dobes aren't as high drive as working Dobes, but they're not low drive either. Sort of inbetween. They do need an owner who will be able to set the rules straight from the beginning and show them who's boss, as with most dogs. They thrive on obedience and love to learn new things. They're an extremely intelligent breed (a little stubborn too though). I reccomend obedience classes for all dogs, no matter what breed as they do need tons of socializing. Some people don't take their Dobes to obedience classes and are lucky that they do well in public around other dogs and people but more often than not, that isn't the case. They also have a Dober whine...which can get quite annoying but they don't whine all of the time, mostly just when they're anxious or excited. They do need exercise and really enjoy running around but they are quite content just to sleep the day away most of the time also, obviously with young Dobes this won't always be the case. Every Doberman I know plays what I and a friend of mine who breeds Dobes called "the stare game"...lol. Basically, when Dobes are around other Dobes they'll be running around having a great time, suddenly stop and stare at eachother. They then, hoepfully without any of the others noticing, stalk the others and whoever moves first gets pounced on. They try this with other breeds too, but it doesn't work too well as other breeds don't understand the game...lol. They also have a Dober grin. When they're happy, excited, etc. They're curl their lips like they're snarling, but they really aren't. Not all Dobes do this, but tons do. That's all I can think of at the moment, but if you have any other specific questions I'll try to answer them
