Immediacy Requirement for Constitutionally Permissible Use of Deadly Force Against Household Pets

Introduction

Love v. Grashorn, decided by the United States Court of Appeals for the Tenth Circuit on April 22, 2025, addresses the Fourth Amendment implications when a police officer shoots a privately owned dog absent an immediate threat. Plaintiffs Wendy Love and Jay Hamm sued Officer Mathew Grashorn after he shot their dog “Herkimer” on private property, claiming the shooting violated their Fourth Amendment rights. The key issues on appeal were (1) whether a reasonable jury could find that Grashorn’s use of deadly force violated the Fourth Amendment, and (2) whether such a violation was clearly established so as to defeat his claim of qualified immunity.

Summary of the Judgment

The district court denied Officer Grashorn’s motion for summary judgment based on qualified immunity, concluding that a jury could reasonably find (a) no immediate danger justified the shooting of Herkimer, and (b) non‐lethal alternatives were available. On appeal, the Tenth Circuit affirmed. It held that under the Fourth Amendment a household pet may not be shot absent an exigent circumstance (i.e., an immediate threat to officer safety or public safety) and that this prohibition was clearly established at the time of the shooting. Because the district court’s factual findings supported a jury’s conclusion that Herkimer posed no imminent danger and that non‐lethal options existed, Grashorn was not entitled to qualified immunity.

Precedents Cited

Mayfield v. Bethards, 826 F.3d 1252 (10th Cir. 2016) – Held that killing a dog “meaningfully and permanently interferes with the owner’s possessory interest” and requires a warrant or exigent circumstance.
Viilo v. Eyre, 547 F.3d 707 (7th Cir. 2008) – Emphasized common‐sense rule that deadly force against a household pet is reasonable only if the pet poses an immediate, unavoidable danger.
Brown v. Muhlenberg, 269 F.3d 205 (3d Cir. 2001) – Recognized Fourth Amendment violations when officers shoot a dog that poses no imminent danger.
Ray v. Roane, 948 F.3d 222 (4th Cir. 2020) – Concluded that shooting a nonthreatening, privately owned animal is unconstitutional and clearly established absent immediate threat.
Morris v. Noe, 672 F.3d 1185 (10th Cir. 2012) – Though involving a person, held that use of force is clearly unreasonable where the subject posed no threat, illustrating the broader principle of objective reasonableness under the Fourth Amendment.

Legal Reasoning

The court applied the two‐step qualified immunity framework:

Did the officer’s conduct violate a constitutional right? Under the Fourth Amendment, killing a household pet is a seizure of property requiring a warrant or exigent circumstance. The district court found disputed issues of fact—specifically whether Herkimer posed an immediate danger or whether non‐lethal means were available—precluding summary judgment.
Was that right clearly established at the time? The court concluded that the consensus of decisions from multiple circuits, coupled with common‐sense expectations of police conduct, made it clear that deadly force against a dog is lawful only if the dog poses an imminent threat and non‐lethal alternatives are unavailable.

The appeals court deferred to the district court’s factual determinations—namely, that a jury could find no exigency and that the owners were present and capable of regaining control—because challenges to those findings would require credibility determinations and weigh evidence, tasks reserved for the jury or district court.

Impact

Love v. Grashorn establishes in the Tenth Circuit a bright‐line rule governing police shootings of household pets: absent an immediate threat to officer or public safety, and absent exigent circumstances, deadly force against a privately owned animal violates the Fourth Amendment. Officers in this circuit will henceforth be on notice that shooting a non‐threatening dog without first pursuing reasonable, non‐lethal measures or waiting for backup is unconstitutional and will not be shielded by qualified immunity. This precedent will guide police training, departmental policies on use of force, and future civil rights litigation involving the protection of private property interests in household animals.

Complex Concepts Simplified

Qualified Immunity – A legal doctrine that shields government officers from liability for civil damages unless they violated a “clearly established” constitutional right that a reasonable officer would have known.
Fourth Amendment Seizure of Property – The Constitution protects private property (including pets); taking or destroying that property typically requires a warrant or an exception such as an immediate threat that cannot be handled otherwise.
Immediate Danger / Exigent Circumstances – Situations so urgent that officers may lawfully use force without a warrant to protect themselves or others from pending harm.
“At Large” Status – In this case, used generally to mean a dog was uncontrolled and free to roam; factual disputes about whether the owners could have called the dog off are for a jury to resolve.

Conclusion

Love v. Grashorn cements the principle that deadly force against a household pet is constitutionally permissible only when there is an immediate threat to officer or public safety and no reasonable, non‐lethal alternative exists. The Tenth Circuit’s reliance on common‐sense expectations and the weight of persuasive authority makes the rule clearly established. This decision underscores the continued judicial insistence on restraint and adherence to constitutional safeguards in police use of force, extending those protections decisively to the private property interests of pet owners.
