The old saying is “Don't bite the hand that feeds you,” but what about the one that’s crowding and pestering you? That appears to be the conundrum one of King Charles III’s guard horses faced at London’s Household Calvary Museum Monday, when a female tourist disregarded posted signs warning people not to get too close to the horse and got her arm chomped for her troubles.

Video footage posted to social media several tourists crowding the horse and its mounted British Army guardsman, despite signs saying it would behoove them not to.

“Beware: Horses might kick or bite,” the sign says. “Don’t touch the reigns. Thank you.”

The horse nipped at a few of the civilians trying to touch it before clamping down on the arm of a woman who rushed at the animal for a photo. She yelped and ran back into the crowd, and can later be seen kneeling on the ground with apparent bruising visible, surrounded by onlookers. According to the caption of the video, she later fainted.

In the footage, other tourists continue to take selfies with the horse after, though notably from a further distance.

A British Army spokesperson shared a statement with Vanity Fair after the incident.

“Whilst every effort is made to ensure public safety, horses may bite or kick,” they said. “We continue to remind the public to adhere to the very clear warning signs and maintain a safe distance.”

This isn’t the first time the royals' horses have said “nay” to tourists: Last month, a woman fell to the ground and claimed she was headbutted by a guard horse, and multiple tourists’ ponytails have been bitten in recent months.

In 2023, in reaction to yet another incident, the United Kingdom Ministry of Defence issued a statement to the New York Post asserting that these working horses are just doing their jobs.

“We want to ensure all those who visit the Horse Guards have an enjoyable time,” the Ministry of Defence said. “This area is particularly busy with tourists. Signs clearly display warnings that animals may bite and for tourists to keep their distance. This is for the safety of those on duty and the public.”

Things could go further than nips and bites, the statement continued: “If this is the case, they are actually allowed to shout warnings at you to make you go away. If people start acting aggressively, the soldiers can even present their bayonets to them.”
