Fox News reported that President Joe Biden's dog bit a Secret Service agent last. This is only the latest in a long series of attacks by the president's pets, some of which have resulted in serious injuries.

The incident is said to have involved a purebred German shepherd named Commander and it occurred at around 8:00 p.m. on September 25.

Biden's dog has bit 11 people since entering the White House

A U.S. Secret Service (USSS) spokesperson confirmed that the agent in question was treated by medical personnel although no further details were provided.

Fox News noted that this is the 11th time that Commander has bitten either a Secret Service agent or a member of the White House staff.

The first family previously kept another German shepherd at the White House named Major who also had a history of biting people.

Fox News reported in 2021 that one Major "sank his teeth into a Secret Service employee," an attack which required medical attention.

Biden defended dog's behavior as an attempt "to protect" him when around strangers

The network recalled how Biden attempted to excuse his pet's behavior during an interview with "Good Morning America."

"Every door you turn to, there's a guy there in a black jacket. You turn a corner, and there's two people you don't know at all. And [Major] moves to protect," the president was quoted as saying.

This phenomenon has drawn the attention of Slate contributor Molly Olmstead, who recently authored a piece titled, "The Bidens' Dog Keeps Biting People. Why?"

Omstead pointed out that "past White House dogs have done fine (the Obama dogs, for example), and two problem dogs in a row almost makes a pattern, meaning there’s probably some part of the equation that’s gone wrong."

Dog trainer wonders why "Commander still has access to people to bite at all"

Juliana DeWillems is the owner and head trainer at JW Dog Training & Behavior Consulting, and she expressed concerns how Commander is being handled.

"My question with this is how Commander still has access to people to bite at all," Omstead quoted DeWillems as saying.

"His environment should be so well-managed that if you know he’s a bite risk, he’s only going to be around people he feels safe and comfortable and well-behaved around," the dog trainer went on to add.
