At home the dog sits the moment he hears the cue. Outside, on seeing another dog, he acts as though he has never met you. So he must be stubborn? Testing boundaries? Knows what we are asking and decides not to obey?
Perhaps. But far more often we are asking the wrong question.
Performing a cue and being able to manage an emotion are not the same skill. A dog can know “sit” perfectly in the kitchen and be physically unable to sit calmly when another dog is barking a few metres away. Not because he has forgotten the word, but because his state and the whole situation have changed: where his attention is, muscle tension, the distance to the trigger, and what seems most important at that moment.
Training teaches actions. Changing behaviour examines the cause
Tricks and everyday behaviour are worth separating clearly: a dog can know a hundred cues and still be hard to live with. Older explanations about hierarchy no longer hold, but the distinction itself remains important.
In training we teach a specific response: sit, lie down, come, let go of an object. In changing behaviour we ask what function the behaviour serves and in what circumstances it appears.
A dog barks at the window. Perhaps he is guarding territory, perhaps he was startled, perhaps he got excited by movement, perhaps the barking makes the passer-by “go away” every time and therefore works perfectly. A “quiet” cue alone will be too narrow for any of these causes.

The first domino
It is useful to look for the first domino — the problem from which everything else starts to fall. Only what you look for is not the dog’s supposed status, but the real chain.
For example, in the evening the dog barks, grabs hands and steals things. We can teach the cues “quiet”, “drop it” and “leave it” as though these were three separate problems. But if the whole chain starts with a young dog not having slept enough, the first solution is rest and a different daily rhythm.
Another dog pulls on the lead, rushes at the gate and cannot settle in the car. The common denominator may be not a “lack of leadership” but very strong arousal the moment he sees the signs of an outing. In that case we teach the dog in small steps to wait calmly while the lead is clipped on, not to barge through opening doors, and to get in and out without rushing.
Look at what happened before and after
A simple three-part framework helps:
- What happened before the behaviour? You picked up your keys, a child came over, a dog appeared, a paw was touched.
- What exactly did the dog do? Froze, barked, backed away, grabbed, jumped — we describe, we do not judge.
- What happened afterwards? The trigger went away, you gave attention, the door opened, the object stayed with the dog.
Behaviour is strengthened not by your intention but by that behaviour’s consequence. If the door opens when the dog barks, the dog learns to open doors by barking. If the dog growls and a person steps back, the growl created distance — that is important information about how the dog feels, not an invitation to punish him.
First check the dog’s health
A sudden change in behaviour should not be treated as a training task until a vet has assessed possible medical causes. A dog who has unexpectedly started snapping when touched may be in pain. Urinating indoors can be a urinary tract problem. Night-time restlessness, irritability or reluctance to climb stairs can also have a physical cause.
A behaviourist or trainer does not replace a vet. A good specialist will themselves ask you to check the dog’s health first if the history contains such signs.

Boundaries are still necessary
Understanding the cause does not mean letting the dog do whatever he likes. If he chases a child, the situation is stopped. If he guards food, children and other animals are kept away from the bowl. If he charges through doors, you use gates, a lead and teach him to wait.
The difference is that management protects now, while training changes the future. A punishment that only silences behaviour briefly can hide the signal without removing the cause.
Modern reward-based training is also not an endless distribution of treats for simply existing. Rewards help create and strengthen new behaviour. Later it is maintained by natural consequences: waiting calmly opens the door, a loose lead allows you to approach a scent, and coming back to your person means you may go off exploring again.
When a trainer is enough and when you need a behaviourist
A qualified trainer working with positive reinforcement methods can teach a dog basic cues, calm lead walking, resting on a mat or good manners at doors. When behaviour is driven by fear or aggression, when the dog panics if left alone, compulsively repeats actions or injures himself, you need a behaviourist — and often a vet’s involvement as well.
What matters is not how many cues a dog knows. What matters is whether he can use them in real life and whether you understand what is stopping him.
