Aggressive behavior
Dog training Hamburg

Aggressive behaviour in a dog towards humans is a challenging and often distressing situation for any dog owner.
If your dog has bitten someone – or you are worried that it might happen – you are not alone.
At SENFHUNDE HAMBURG, I support you with empathy and solid expertise to help restore balance in the relationship between you and your dog.
>> What should I do if my dog has bitten someone? First of all: take a breath. A bite incident is stressful and often frightening for any owner. What matters now is staying calm and planning the next steps carefully. The first step is to analyse the situation: Why did your dog bite? Was there provocation or a stressful environment? These questions help us understand the cause of the behaviour. At my dog training school in Hamburg, I work with you to identify the precise triggers. We use evidence-based dog training in Hamburg, tailored to your dog’s needs. Professional training can help you rebuild trust in your dog and prevent further incidents.
>> How Can I Prevent My Dog from Biting Again? The most important step is to identify the triggers for the biting behaviour and work on them systematically. Often, fear, insecurity, or overwhelm are the underlying reasons for aggression. With clearly structured dog training in Hamburg, you can support your dog in coping better with these situations. At my Hamburg dog school, I show you how to provide your dog with alternatives to biting. Together, we train how to reduce stress and how you can guide your dog safely through difficult situations. I place great emphasis on positive, force-free methods to strengthen trust between you and your dog. We will also discuss whether muzzle training is advisable – and what a step-by-step muzzle training plan can look like.
>> Does My Dog Have to Wear a Muzzle Now? After a bite incident, it can be sensible – or even required – for your dog to wear a muzzle, especially during encounters with other people or dogs. In Hamburg, authorities may order the use of a muzzle if a dog is classified as dangerous. But a muzzle is not a punishment! With the right training, your dog can learn to accept the muzzle as a neutral, or even positive, companion. At my Hamburg dog school, I support you in helping your dog get used to the muzzle in a stress-free and positive way. This way, the muzzle is not seen as a restriction but as a safety measure.
>> Do I Maybe Have to Give My Dog Away? This is perhaps one of the hardest and most emotional questions an owner can face after a bite incident. The good news: in most cases, it is not necessary. With tailored dog training in Hamburg, you can give your dog the support they need to change their behaviour. At my Hamburg dog school, we work together to understand the causes of your dog’s behaviour and improve it sustainably. I help you build a strong bond and regain trust in your dog. Rehoming is, in most cases, only ever the very last step – and I’ll be there with guidance and support to ensure it never has to come to that.
I completed Michael Shikashio’s Aggression in Dogs Master Course and undertook additional training as a behaviour consultant at the ATN Academy.
Aggressive behaviour is my heartfelt speciality, because I know from personal experience how demanding it can be:
my own dog, Nana, bit my husband several times shortly after her adoption. I understand your worries, your fears, and the hopelessness that can creep in—perhaps better than most. But I can assure you:
There are ALWAYS solutions and a way forward.
Important to know:
a dog that has bitten does not need a heavy hand, punishment, or force. Approaches like these only make things worse and often lead to a spiral of escalation. Lasting change is achieved through understanding, identifying root causes, and positive, evidence-based work.
Let me illustrate:
imagine a pot of water boiling over on a hot hob. What do you do?
You take it off the heat—you don’t just press the lid down harder.
It’s the same with aggressive behaviour: we need to remove the cause from the “heat” and show your dog there are other ways to respond to stress or fear.
With my blend of professional expertise, personal experience, empathy, and a solid scientific foundation, I’ll guide you step by step—so you and your dog can find your way back to a harmonious partnership.

A big challenge: My dog has bitten me – what now?
A bite incident can have many causes — fear, stress, insecurity, or miscommunication between human and dog. What matters now is to act calmly and seek professional support. As an experienced dog trainer and behaviour consultant in Hamburg’s north, I analyse the individual triggers behind your dog’s behaviour, because aggressive dogs in Hamburg need targeted, individual support that addresses the underlying causes.
We will work on together:
-
Root-cause analysis: Why is your dog showing aggressive behaviour?
-
Action plan: Clear, concrete steps to change the behaviour.
-
Prevention: Strategies to avoid similar situations in future — and, where appropriate, a structured muzzle-training plan.
Behavioural Therapy for Aggressive Behaviour
Aggressive behaviour cannot simply be “trained away” – it requires in-depth behavioural therapy. I always rely on force-free, positive training combined with needs-based and scientifically grounded methods. Together, we’ll work on helping your dog learn alternative behaviours and develop a greater sense of security.
Temperament test in Hamburg
In Hamburg, a behavioural assessment (Wesenstest) may be required after a bite incident. I support you and your dog with targeted training to prepare you both in the best possible way.
>> What Is a Behavioural Assessment (Wesenstest)? A Wesenstest is a behavioural examination designed to assess a dog’s aggression levels and social behaviour. After a bite incident, such a test can be required by the authorities to determine whether the dog poses a risk to the public. During the assessment, typical everyday situations are simulated – for example, encounters with people or other dogs. The aim is to evaluate the dog’s responses and decide whether they can be safely managed in public spaces.
>> Does My Dog Need a Behavioural Assessment (Wesenstest)? Whether your dog needs a behavioural assessment depends on the circumstances. After a bite incident or a report to the veterinary authority, the authorities may order a Wesenstest. This is used to assess your dog’s behaviour in more detail. In Hamburg, such an assessment is often required if a dog has shown aggressive behaviour – whether towards humans or other dogs. I help you evaluate the situation correctly and support you in preparing, should a Wesenstest be necessary. Together, we’ll work to ensure your dog can present themselves safely and calmly.
>> Can I Do the Behavioural Assessment (Wesenstest) with You? I don’t conduct Wesenstests myself, but I provide comprehensive support in preparing for them and help you find a qualified examiner or institution in Hamburg. Throughout the process, I’ll be by your side – answering your questions and working with you so that you and your dog are well prepared to pass the assessment successfully.
>> How Do I Find a Dog Trainer or Someone to Conduct a Behavioural Assessment (Wesenstest) in Hamburg? In Hamburg, there are certified institutions and dog trainers authorised to carry out a Wesenstest. If you’re unsure whom to contact, I’ll gladly help! I have a network of experienced professionals who can support in such cases. In addition, I work with you to prepare your dog in the best possible way – whether through targeted exercises or a behavioural analysis that highlights what we should pay special attention to. Together, we’ll ensure that you, as a team, are optimally prepared for the assessment.
