Members of President Joe Biden’s staff are concerned about Commander, Biden’s German Shepherd that bit a Secret Service officer in late September.

"Among staff, there is an emerging belief that, in the eyes of Commander, they are off limits; that the dog only has an appetite for the Secret Service," Politico reported. 

"It’s shocking that he can be so aggressive," one White House staffer said. "I’ve never seen him like that."

It was Commander’s eleventh known biting incident. Conservative legal activist group Judicial Watch previously obtained reports of the 10 previous incidents of Commander terrorizing staff from October 2022 through January 2023.

One of the more serious incidents resulted in the victim, a Secret Service agent, being taken to the hospital after his interaction with the first dog. The victim was bitten on his thigh and arm on Nov. 3, 2022.

Biden’s staff are divided on Biden’s dog, according to a Politico report from Monday.

"Everyone loves him," a White House staffer said. "He’s always so friendly."

Others in Biden's staff were not as positive about Commander, with some theorizing reasons as to why Commander seems to be interested in specifically attacking Secret Service officers, per Politico.

"The White House is just a crazy environment for a dog," a former White House official said. "There are enormous men with guns acting suspiciously hostile everywhere."

Another former staffer had a different theory. 

"Dogs are very reactive to humans and when staff greet Commander, it’s usually with a big smile," the staffer said. "That’s not the case for Secret Service agents, who tend to be less warm and fuzzy while on the job."

"As we’ve noted before, the White House can be a stressful environment for family pets, and the First Family continues to work on ways to help Commander handle the often unpredictable nature of the White House grounds," a spokesperson for the First Lady told Politico. "The President and First Lady are incredibly grateful to the Secret Service and Executive Residence staff for all they do to keep them, their family, and the country safe."

"But whatever additional training Commander is getting hasn’t seemed to do the trick yet. Some White House staffers and reporters have running bets among themselves about how much longer until the Bidens will be forced to send Commander away, too," Politico wrote. "Sometime before Thanksgiving seems to be a popular take among reporters."

"We do wonder how much longer they can keep him around," a White House staffer told Politico. "At a certain point, it becomes impossible."

The White House did not respond to a request for comment from Fox News Digital.
