The relationship between dogs and postal or delivery workers can sometimes be a difficult one, but there is often a simple behavioural reason behind it.

From the dog’s point of view, a stranger approaches the house, comes towards the door and the dog barks. A few moments later, the person leaves. The dog may believe their barking worked and successfully made the stranger go away.

What the dog doesn’t understand is that the person was always going to leave.

Dogs repeat behaviours that work for them. If barking, lunging or rushing towards the door appears to make the “scary” person disappear, they are more likely to do it again. The more often this cycle is repeated, the stronger and more intense the behaviour can become.

The aim is to break this cycle while keeping the dog, owner and delivery worker safe.

What Owners Can Do:

1. Limit the barking cycle

Preventing a dog from repeatedly practising the behaviour is an important first step. If a dog spends every day watching people approach through a window, barking at the gate or rushing to the front door, they are getting lots of opportunities to rehearse that response.

Window film, curtains, barriers and restricting access to the front of the house can all help.

2. Limit access to the front door

Dogs do not need to greet every person who comes to the door.

Use baby gates, closed internal doors or another secure area to prevent your dog from rushing towards the entrance. This is particularly important if your dog becomes fearful, frustrated or highly excited when someone arrives.

For some dogs, simply being in another room while a delivery takes place is the safest and least stressful option.

Over time, you can train your dog to go to and settle on a designated bed or mat when someone comes to the door. However, this needs to be built up gradually and practised away from real deliveries first. Until you are confident your dog can remain there when someone arrives, continue to use a physical barrier or closed door for safety.

3. Create a positive association with deliveries

If your dog is able to take treats when someone approaches, start pairing deliveries with something positive.

When a delivery person arrives, scatter a handful of high-value treats on the floor away from the front door. This encourages your dog to move away from the person while also beginning to change how they feel about someone arriving.

If your dog is too stressed to eat, this is important information. They may be over threshold, meaning they are too stressed or overwhelmed to learn effectively at that moment. Increase the distance between your dog and the trigger, such as moving them into another room, and work at a level they can comfortably manage.

If your dog regularly reacts to the doorbell, people at the gate, visitors or anyone approaching the house, this is likely to be a wider behavioural issue rather than a problem specifically with postal or delivery workers. In this situation, owners should consider seeking professional training or behavioural support.

Owners are ultimately responsible for safely managing their dog’s access to the door and addressing any wider fear, frustration or reactivity around people approaching the home.

Sometimes, the safest and kindest interaction is no interaction at all.
