President Joe Bidens dog Commander bit people on multiple occasions, both in Washington, D.C., and in Delaware, during a four-month stretch last year, U.S. Secret Service communications show.

According to emails obtained by the conservative group Judicial Watch, Secret Service personnel reached out to the agency several times with concerns about the 22-month-old German shepherd and his aggressive behavior between October 2022 and January 2023.

The communications, which were obtained via a Freedom of Information Act request, documented 10 incidents in particular, including one where an officer had to go to the hospital after Commander bit his arm and thigh. In another instance, the dog bit an agent so hard he left cuts and bruises on the agents arm.

The White House on Tuesday told CNN that Commander, who moved to the capital in 2021, is working on new training .
