Aggressive dog behaviour: assessment, safety and progressive behaviour work
If your dog growls, threatens, lunges, snaps, bites or creates risky situations, it is important to assess the case properly and set up a safe plan before continuing exposure.
Tell us your situationNot every dog that shows aggression is a “bad dog”
Aggressive behaviour can appear because of fear, pain, insecurity, resource guarding, space defence, frustration, previous experiences, poor emotional regulation or learned behaviour.
Before labelling the dog, we need to understand what is happening, what triggers the behaviour, which warning signs appear first and what level of risk exists for people, dogs or other animals.
Risk behaviours
Signs that need assessment
If these behaviours appear, prevention is essential and improvising can increase risk.
2
Snapping or biting
The dog has already used their mouth, marked skin, caused injury or bitten with more intensity.
3
Strong lunging
They react towards people, dogs, bikes, visitors or other triggers with loss of control.
4
Resource guarding
They defend food, toys, beds, people, spaces or objects with tension or threat.
5
Handling intolerance
They react to touch, collar, harness, grooming, veterinary handling or physical contact.
6
Risk at home
There are conflicts with children, visitors, family members, other dogs or animals in the household.

How we work with aggressive behaviour
The priority is safety, risk assessment and a realistic plan.
1
We assess the risk
We analyse intensity, frequency, bite history, context and the people or animals involved.
2
We identify triggers
We look for what activates the behaviour: fear, resources, invasion, pain, frustration or stress.
3
Safety measures
We define handling, distance, environmental control, prevention and muzzle work if the case requires it.
4
Reducing risky exposure
We prevent repeated situations that could lead to new bites or reinforce the behaviour pattern.
5
Progressive behaviour work
We work on distance, emotion, self-control, alternative behaviours and controlled exposure.
6
Family guidance
Everyone must know what to do, what to avoid and how to handle the dog safely.
Common mistakes in aggression cases
- Punishing growling and removing the dog’s warning signals.
- Forcing approaches “so the dog gets used to it”.
- Exposing the dog to children, dogs or visitors without enough control.
- Using physical corrections when the dog is already overwhelmed.
- Waiting until a serious bite happens before asking for help.
- Not ruling out pain, discomfort or veterinary issues when appropriate.
Aggressive behaviour
We work with prevention, safety and behaviour modification to reduce risk and improve how the dog is managed.
Who this work is for
- Dogs that have growled, snapped or bitten.
- Dogs that lunge strongly towards people or other dogs.
- Dogs that guard resources with threats or bites.
- Families with children, visitors or other animals at home.
- Cases where daily life is starting to feel unsafe.
Important: safety and veterinary assessment
In some cases, aggressive behaviour may be linked to pain, illness, hormonal changes, cognitive decline, neurological issues or physical discomfort. If there is any suspicion, we recommend veterinary assessment.
If there is a bite risk, a properly conditioned muzzle can be a safety tool, not a punishment.
