President Biden's Dog Commander Bit Secret Service Agents On 24 Occasions

More insight on the biting problems with President Biden's family dog Commander ... the German Shepherd bit Secret Service agents on at least two dozen occasions.

Commander is no longer living with the Bidens at the White House ... but when he was, the Secret Service had to change their tactics as a result of all the biting incidents.

The staggering figure is revealed in new internal Secret Service documents obtained by CNN ... and the 24 biting incidents don't even include the times Commander chomped on members of the White House staff ... only incidents with the SS are documented here.

Commander not only sunk his teeth into agents at 1600 Pennsylvania Avenue, he also attacked them at two Biden family homes in Delaware ... plus trips to Nantucket and Camp David.

Biden's dog bit members of the Prez's protective detail, plus other uniformed Secret Service agents ... and in at least 10 instances, the Secret Service agent who was bit required medical treatment.

Commander bit agents on their arms, hands, legs and even their waists.

As we reported ... Commander was kicked out of the White House back in October as a result of his human-biting ways. At the time, the Secret Service only acknowledged 11 biting incidents.

In the months leading up to Commander's ouster, the Secret Service issued this warning in an internal memo ... "The recent dog bites have challenged us to adjust our operational tactics when Commander is present – please give lots of room."

The warning also said Secret Service agents "must be creative to ensure our own personal safety."
