Royal Mail is urging households with dogs to display a simple warning sign because dog attacks on postal workers have continued to rise across the UK.
The recommended four-word message, “I have a dog”, gives posties time to wait while you secure your pet before opening the door.
Royal Mail says this could help prevent injuries, avoid delivery delays and reduce the risk of services being suspended to your address.
Key points include:
- Dog attacks on Royal Mail workers rose to 2,197 in 2024/25
- That equals around 42 incidents every week
- Royal Mail may suspend deliveries where dogs remain a safety risk
- The suggested sign should be placed where it is clearly visible
- Additional safety measures, such as securing gates and fitting letterbox cages, are also recommended
Here’s everything you need to know about the 4-word sign, why it matters, and how it could protect your deliveries.
Why Has Royal Mail Started Recommending a Dog Warning Sign Now?
Royal Mail has renewed its campaign as dog attacks on postal workers continue to rise. Latest figures show incidents increased by 2% in the past year, reaching 2,197 cases, around 42 attacks every week across the UK.
This becomes more concerning during busy periods like Easter and bank holidays, when higher parcel volumes mean more doorstep visits and an increased risk of sudden dog reactions.
Even calm pets can become startled when the door opens, leading to unexpected incidents.
- 2,197 dog attacks recorded in 2024/25
- Around 42 incidents per week
- Higher risk during peak delivery periods
Lizz Lloyd, Health and Safety Director at Royal Mail, explained the concern clearly:
“Dog attacks remain one of the most significant safety risks faced by postal workers. In many cases, these incidents result in serious injuries, emotional distress, and time away from work.”
Royal Mail believes a visible warning sign is one of the quickest and easiest ways to reduce that risk.
What Exactly is the Four-word Royal Mail Dog Warning Sign?
The “four-word” warning sign recommended by Royal Mail is simply “I have a dog.”
This short message is designed to alert delivery workers to pause and wait before the door is opened, giving homeowners time to safely secure their pet.
Royal Mail also provides a longer version of the message for added clarity. “I HAVE A DOG. Please wait whilst I secure my dog before opening the door.”
This has caused some confusion, as some reports refer to a four-word sign while others mention longer versions. In reality, the shorter phrase acts as the main alert, while the extended message gives clear instructions.
The sign can be downloaded from the Royal Mail website, but it does not have to be official. A simple handwritten or printed notice works just as well, as long as it is clearly visible.
Royal Mail recommends displaying the sign in advance rather than after an incident, helping prevent problems before they occur.
Why Are Dog Attacks on Royal Mail Workers Still Increasing Across the UK?
Despite years of awareness campaigns, dog attacks on postal workers continue to rise because many owners underestimate how their pet may behave at the front door.
A dog that is friendly around family members can still react differently when a stranger appears at the property.
Many attacks happen in predictable situations:
- A dog rushes through the front door when it is opened
- A pet escapes from a side gate or garden
- A postie is bitten through the letterbox
- A dog becomes territorial when a parcel is delivered
Royal Mail has repeatedly warned that both large and small dogs can cause injuries. According to the organisation, around 2,000 posties are injured every year by dogs of all breeds and sizes.
A Royal Mail spokesperson said:
“Around 2,000 posties like me are injured by dogs each year, both big and small. When this happens, we must inform the police and suspend deliveries to your address.”
The emotional impact is also significant. Some workers require time off, while others may lose confidence returning to homes where a dog has previously attacked them.
Common Situations Where Attacks Happen
The most frequent incidents involve:
- Opening the front door without securing the dog first
- Dogs are reaching the front of the property through open side gates
- Hands being bitten through letterboxes
- Dogs are becoming overexcited when multiple deliveries arrive
Royal Mail says many injuries happen in a matter of seconds. A postie may not even enter the property before a dog runs outside or jumps at them.
This is why the organisation is focusing on simple preventive measures that can be used by every household.
Why Can Even Friendly Dogs Become Unpredictable?
Dogs often react instinctively to unexpected noises or unfamiliar visitors. Doorbells, parcel deliveries and post coming through the letterbox can trigger excitement or anxiety.
This is why Royal Mail stresses that even dogs with no history of aggression should be controlled before the door is opened.
Could Your Deliveries Really Be Suspended if You Do Not Display a Dog Warning Sign?
Yes, Royal Mail can suspend deliveries if a dog is considered a safety risk. This is an official policy, not just guidance. If a postie feels threatened or an incident occurs, it may be reported, and deliveries can be paused until the risk is addressed.
This does not always mean a permanent stop, but it can be inconvenient. You may need to collect letters and parcels from a delivery office instead of receiving them at home.
Royal Mail has made its position clear in letters to customers:
“Receiving your letters and parcels is important, but our priority is to get these items to you safely.”
In most cases, a warning sign and evidence that you are taking precautions will help prevent further action.
Royal Mail is not asking households to remove their pets; it simply wants owners to show that the situation is under control.
Where Should You Place the Royal Mail Dog Warning Sign Around Your Home?
The sign only works if the postie sees it before approaching the door. For that reason, Royal Mail advises placing it somewhere obvious and impossible to miss.
The best locations include:
- On the front door at eye level
- In a nearby window facing the driveway or path
- On the front gate if your dog is kept in the garden
- Beside the letterbox if there is a risk of bites through the flap
A sign hidden behind curtains or placed inside the hallway is unlikely to be effective. The message should be visible before the delivery worker reaches the entrance.
| Best Place for the Sign | Why It Works |
| Front door | Seen immediately before you answer |
| Front window | Visible from the path or driveway |
| Front gate | Warns the postie before entering the property |
| Near the letterbox | Helps reduce the risk of bites through the flap |
Some households may benefit from using more than one sign, especially if deliveries could come through different entrances.
What Should You Do Before Opening the Door to a Postie if You Have a Dog?
Putting up a sign is only the first step. You should also make sure your dog is fully under control before opening the door.
A few extra seconds can prevent an accident and make the delivery process easier for everyone.
Practical Safety Measures for Households
Before answering the door:
- Put your dog in another room
- Keep the dog behind a secure baby gate or internal door
- Wait until the dog is calm before opening the front door
- Ask the postie to leave the parcel on the doorstep if necessary
Royal Mail says postal workers are happy to wait while you secure your pet. Taking an extra few seconds is far safer than trying to hold a dog back with one hand while opening the door with the other.
Ways to Prevent Dogs From Reaching the Front Door
You should also think about how your property is arranged. If your dog can run from the back garden to the front of the house, there is a greater risk of an incident.
Useful changes include:
- Closing side gates before deliveries are expected
- Keeping dogs indoors when you are waiting for a parcel
- Installing barriers inside the hallway
- Using toys or treats to distract an excitable dog
One dog owner from Nottingham, Sarah Mitchell, said she started using the sign after her Labrador repeatedly barked and tried to push through the front door whenever the post arrived.
“I never thought he would actually bite anyone, but he became very protective at the door. Since putting up the sign and keeping him in the kitchen during deliveries, it has made a huge difference.”
Her experience shows that even owners of friendly dogs can benefit from taking a few simple precautions.
Which Uk Postcode Areas Have the Highest Number of Dog Attacks on Posties?
Royal Mail’s latest figures show that some parts of the UK are much more affected than others. Sheffield remains the most dangerous area for postal workers, while several other regions have seen sharp increases.
| Rank | Postcode Area | Number of Attacks | Change from Previous Year |
| 1 | S (Sheffield) | 66 | Up 61% |
| 2 | PO (Portsmouth) | 60 | Down 3% |
| 3 | TN (Kent, Sussex and Surrey) | 56 | Up 33% |
| 4 | GU (Guildford) | 54 | Up 29% |
| 5 | NG (Nottingham) | 49 | Up 17% |
Sheffield has appeared on Royal Mail’s high-risk list every year since postcode-specific reporting began. Portsmouth, Nottingham and Brighton have also repeatedly featured in the most dangerous areas for attacks.
The data suggests that this is not an isolated issue affecting only a handful of households. Dog-related incidents are widespread across the UK and continue to affect postal workers in both urban and rural areas.
How Can a Simple “I Have a Dog” Sign Help Protect Both Your Pet and Your Postie?
The Royal Mail dog warning sign is not only about protecting delivery staff. It can also help keep your pet safe.
A dog that escapes through the front door may run into the road, become distressed or injure itself. By placing a sign on the door, you create a reminder for yourself as well as for the postie.
The sign also changes the interaction. Instead of opening the door immediately, you are encouraged to pause, secure your dog and make the delivery safer for everyone.
This simple step can prevent:
- Bites and scratches
- Dogs escaping from the property
- Stress for delivery workers
- Missed or suspended deliveries
For many households, the sign is a low-cost way to avoid much bigger problems later. It may also help prevent complaints, arguments or the worry of dealing with an injured postal worker.
What Other Steps Can You Take to Make Your Home Safer for Delivery Workers?
If your dog regularly reacts to deliveries, you may need more than a sign alone. Royal Mail recommends making small changes around the home to reduce the risk further and make deliveries safer in the long term.
Letterbox and Gate Safety Improvements
One of the most common causes of injury is a dog biting through the letterbox. Installing a wire letterbox cage on the inside of the door can stop hands from reaching the dog and prevent bites.
This is particularly useful if your dog becomes excited whenever letters are pushed through the flap.
You may also want to:
- Fit a stronger gate between the front and back garden
- Install a self-closing latch on side entrances
- Move your dog’s bed or crate away from the front door
These changes can help stop your dog from rushing towards the entrance whenever somebody arrives.
Alternative Delivery Arrangements
Some households choose to place an external mailbox at the edge of the property. This means the postie does not need to approach the house at all.
Other options include:
- Using a parcel box
- Choosing a safe place delivery option
- Collecting parcels from a local delivery office
These solutions can be especially useful if your dog becomes highly anxious whenever somebody comes to the door.
Why Should Every Dog Owner Take Royal Mail’s Warning Seriously?
Royal Mail’s message is simple: if you have a dog, take steps now to protect both your pet and the people delivering your post. The rise to 2,197 dog attacks in a single year shows that the issue is becoming more serious.
A warning sign saying “I have a dog” may seem small, but it gives delivery workers a chance to pause and allows you time to secure your pet. Combined with sensible precautions, it can help avoid injury, prevent disruption and keep deliveries running smoothly.
The advice is not about blaming dog owners. It is about recognising that even well-behaved pets can react unexpectedly when someone comes to the door.
By acting now, you can make your home safer and avoid the possibility of Royal Mail suspending your deliveries.
Conclusion
In summary, Royal Mail’s advice to display an “I have a dog” sign is a simple but effective way to protect both postal workers and your pet.
With dog attacks on posties continuing to rise across the UK, taking a few precautions before opening the door can help prevent injuries and avoid delivery suspensions.
By placing a clear warning sign, securing your dog and improving safety around your home, you can ensure deliveries remain safe, smooth and stress-free for everyone involved
