A police dog can’t be sued under § 1983, although the handler can. Here, the handler has qualified immunity for this use of force. Jones v. Fransen, 2017 U.S. App. LEXIS 8816 (11th Cir. May 19, 2017):
And to the list of infamous Dracos, add Defendant-Appellant Draco. Draco is a police canine who was involved in the apprehension of Plaintiff Randall Kevin Jones. Unfortunately, Draco inflicted some serious damage on Jones when Draco refused to release his bite. Jones sued Draco, among others, for negligence. Georgia law by its terms, however, does not provide for negligence actions directly against dogs. We therefore hold as much today and reverse the district court’s denial of Defendant-Appellants’ motion to dismiss Draco.
But while Georgia law does not allow for a negligence suit against a dog, it does permit negligence claims against a state officer who is not entitled to official immunity. Title 42, United States Code, Section 1983 likewise authorizes an action against a police officer who employs a dog in an exercise of excessive force. And Jones also sued the officers responsible for Draco’s encounter with Jones. In response, Defendant-Appellant Officers invoked official and qualified immunity and moved to dismiss. The district court summarily denied Defendant-Appellant Officers’ motion. Today we must reverse that denial and dismiss the claims. Jones has failed to allege facts establishing that the officer acted with malice, so the officers are entitled to official immunity. Nor does binding precedent allow for the conclusion that Defendant Officers’ employment of Draco in the circumstances of this case violated Jones’s clearly established rights, so the officers have qualified immunity.
