Doberman's fell out of favor because they attack people. It is a fact and we are 100% aware of it which is why we train our dogs the way we do. Dobermans are pretty misunderstood.
You hear everyone say LGDs are a whole different kind of dog.....Dobie's are too. LGDs and Dobies are the smartest dogs I have ever owned, worked with or been around. They are the easiest dogs ive found to house break, to train obedience commands to, just easy to work with.
The number one personality trait of a dobie is in my opinion loyalty. They are literally loyal to death to their humans/family. Dobie's are used pretty often as police dogs because of this trait the downside is dobie's can not easily be transferred between officers if the need arises.
Dobie's are smart on a different level they will try to work out more efficient ways to do anything asked of them, beyond what you taught them. You give them a command and they literally think about it for a second before doing it. They are not thinking about how to not do the thing asked they are thinking if there is a better way to accomplish the end goal. If your routine is to always ask your dog to sit and then lay down, the dobie will skip sitting when you ask and just lay down because that is the end goal. We were training our dobie to shake paws, we would ask him to sit then immediately after to shake, he decided to take out the middle man and when we said sit to just offer his paw instead, again get to the end goal faster and more efficiently. If you trained a dobie to take a certain path to some destination every single day, unlike many other breeds they will decide on their own to try to find a quicker way to the end location vs the path you taught them. We taught our dogs to come to our side backdoor when we moved into our new house, after about 3 days they evaluated the situation and decided it would be faster and more direct to come to the back sliding glass door to be let in. They were right as the side back door is separated from our house by a mud room and took longer for us to get to it to left them in.
The problem with dobies is the loyalty and their ability to sense peoples actions. If a dobie does not like someone there is a reason for it. Likewise people will say....the dobie attacked them and they were not even doing anything.....yet. Dobie's attack so much because of the ability to sense people's actions and intentions and their built in loyalty along with their need to protect. They were literally bred to protect their humans. They do not differentiate an aggressive adult from an aggressive child, they see this thing(person, animal, whatever) is hurting my humans and attack the thing doing the hurting. It makes perfect sense to the dog and he is doing nothing wrong nevermind one kid hitting another kid because they got mad is not a valid reason for attacking them.
Thankfully due to dobies being so smart if you train them properly they will never attack anything without being told to. All of our dobie's are trained to attack on command and ONLY on command. They are not to touch or show any form of aggressive to anyone or anything unless given their attack command. Even after given the command they will pause for a second to think about the best way to attack the thing. We have thus far never had a dog attack anyone or anything and never needed to use an attack command. They are trained even if a thing hurts them they are not to attack it. DH used to train Dobermans for police dogs, watch video of doberman police dog training, this is the training our dobie's get starting as puppies at 8 weeks old. We no longer breed or sell dobie's DH used too.
Dobie's were not made to be hunting dogs. Dobie's were bred to be loyal guard dogs, the fact they are sight hounds came secondary. Their intelligence makes them able to perform any job a person cares to train them to do. In our experience with dobie's there are two main personalities. The highly energetic playful type and the more toned down straight to business not very playful type. We have owned both.
As far as being around children in general I have zero fear of any child around our dogs, I know their training. I have watched them with a 2yr old walking on them, pulling on their ears, poking their eyes, biting them, hanging off of them, sitting on them, zero reaction came from our dogs other then looking at the child and trying to figure out why it was doing the things it was doing. That is part of our training, they are not to react to pain or discomfort, humans can touch them anyplace on their body in any fashion and they are not to protest in any fashion and certainly never to show aggression. To the point when we first got our kitten I watched the kitten jump up while playing and hang off our dobie's face with it claws while the kitten chewed on the dobie's top lip, the dobie's did nothing more then stand there and wait for the kitten to let go.
Another very important part of training a dobie is confidence, the dog has to have confidence in everything it does. There is no room for being uncertain or scared of anything. An uncertain, unconfident, scared dog is a dangerous dog in any breed.
We condition for noise as well, all noises, they are not be afraid of noises. Guns, fireworks, thunder, chainsaws, 4-wheelers, cars, semi's, tractors, yelling, etc. Our dobie's are taken to the fireworks shows, 4-h auction and truck pulls every year, they sleep through them.
Dobie's do not fight for attention unless you train them too. They understand when it is time for them to get attention and when it is not. When it is time to be excited and when it is not. We train our dobie's with the way we pet them on what the appropriate attitude is. Slow firm reassuring pets, its time to be calm there is nothing to be excited or worried about right now and they should just lay down and relax. Fast light pets its time to be excited, to play and to run around.
So my very long winded response is yes I think a dobie could work for your situation, with proper training. If you are the type of person who wants to only train with positive rewards, dont get a dobie. I do not personally feel a dobie can be reliably trained with only a positive rewards system. They need to know you are the alpha in all things and they are never to challenge that for any reason, their place in the pack and their job role is very secure and very well understood, they have nothing to question. We do not abuse our dogs, and I am not suggesting anyone else does. Training a dog to accept pain in certain circumstances is a very different thing then just beating up a dog. Our dogs are trained with a combination system that does include positive rewards, it is simply not the only means of training. Our dobies are highly trained well adjusted well mannered dogs who appear happy and fulfilled with their life. They do not cower to humans or have any other behavior of an abused dog so please no one twist this around to try to say I am telling people to abuse their dogs. If you watch police dog training videos and think the dogs are being abused, any guard breed is not for you esp a dobie.
