President Joe Biden’s younger dog, Commander, bit another US Secret Service agent at the White House, CNN has learned, the 11th known biting incident involving the 2-year-old German Shepherd.

“Yesterday around 8 p.m., a Secret Service Uniformed Division police officer came in contact with a First Family pet and was bitten. The officer was treated by medical personnel on complex”, USSS chief of communications Anthony Guglielmi told CNN in a statement.

The injured officer spoke with Secret Service Uniformed Division Chief Alfonso M. Dyson Sr. on Tuesday and is doing OK, Guglielmi said.

Commander has been involved in at least 11 biting incidents at the White House and in Delaware, according to CNN reporting and US Secret Service email correspondence, including a November 2022 incident where an officer was hospitalized after the dog clamped down on their arms and thighs.
