The premise is incredibly simple. You print a four-word postcard and stick it to your front door.
But the reality driving this sudden request from Royal Mail is a growing occupational crisis. Postal workers across the UK are facing a severe spike in dog attacks, with recent safety statistics logging 2,197 physical incidents over the last recording year. That breaks down to roughly 42 attacks every single week. Now, the delivery giant is drawing a hard line.
Starting this week, Royal Mail is urging British pet owners to display a highly visible sign reading “I have a dog.” Residents who fail to secure their pets before opening the door face a stark consequence. The company will formally suspend mail deliveries to that specific address to protect its staff.
The warning comes as households navigate changing lifestyle routines that keep pets indoors during prime delivery hours. The four-word sign is designed to buy postal workers a few crucial seconds. It signals the postie to wait safely outside while the homeowner locks their dog in a separate room.
The severity of the issue varies wildly by region, according to a detailed report released on Monday. The Sheffield (S) postcode area is currently the most dangerous zone in the UK for postal workers. The region saw a massive 61% jump in incidents, recording 66 attacks. Portsmouth (PO) followed closely with 60 attacks. The TN postcode covering Kent, Sussex, and Surrey ranked third with 56 recorded incidents.
Corporate leadership is refusing to let the numbers climb further. The physical toll on workers ranges from severe bites to permanent finger amputations caused by dogs snapping blindly through letterboxes.
“Dog attacks remain one of the most significant safety risks faced by postal workers,” Lizz Lloyd, Health and Safety Director at Royal Mail, said in an official statement. “In many cases, these incidents result in serious injuries, emotional distress, and time away from work.”
Lloyd was blunt about the need for immediate public cooperation. “Royal Mail continues to call on the public to be vigilant and responsible by securing their pets before opening the door to receive mail or packages.”
The company confirmed it will continue investing in employee safety training. But the burden is now shifting directly onto the homeowner to secure the property line. Put up the sign. Lock away the dog. Or risk losing your mail entirely.
