I would advice anyone against having a Dobermann.
I got a Dobermann puppy after being told what amazing family dogs they are, I bought an 8 week old female. First couple of weeks was great, she was practically housetrained in two weeks, had learnt a number of basic command (including sit, down, come, stay and wait for your food) and I was amazed by her intelligence.
At 10 weeks old I heard her growling in the garden - thought that was unusual for a 10 week old pup, went to see what she was moaning at and discovered that next doors child had come into the garden and she was stood growling at him. V. Concerning. From here on out she regularly growled at the back door and in the garden.
Still, thought young puppies can’t be aggressive! I continued to do everything by the book … took her to puppy obedience class (where she absolutely excelled) and to puppy socialisation classes … at the socialisation classes she began attacking the other puppies, literally going for their throats (remember she was just a puppy herself). We were asked to leave.
A few weeks later I messaged the breeder saying I was concerned as she was growling at people on walks. He told me to do positive reinforcement training with her (such a young puppy should not be reactive!). By 5 months old she was incredibly reactive towards other dogs and attacked a bulldog.
Fast forward to now, at 4 years old and after 4 years of intense training she is STILL dog reactive, cat reactive, unpredictable with people, cannot EVER be around children, we can’t have anyone in the house and I spend every day worrying about what would happen if she ever escaped the house. We now have double locks on the back gate (for others protection, not ours) and a new front door which automatically closes itself.
All of her siblings are the same. One has attacked its owners and the others im in touch with are unpredictable, reactive and nervous wrecks. I would NEVER have another one.
Just join a Dobermann group on Facebook and search for the words “reactive” or “aggression” and you’ll see how worryingly common it is in the breed.
