Appeal from the United States District Court
for the District of Arizona
Dominic Lanza, District Judge, Presiding
Argued and Submitted July 11, 2024
San Francisco, California
Before: HIGGINSON,** MENDOZA, and DESAI, Circuit Judges.
Dillon Rock brought a 42 U.S.C. § 1983 action against Goodyear Police
Department Officer Mike Miller, Corporal Nathan Cummings, Sergeant Ryan
McCarthy, and Officers Scott Preston, Aaron Torres, and Josh White for violating
his right to be free from excessive force under the Fourth Amendment. Defendants
moved for summary judgment on qualified immunity grounds, and the district court
granted the motion as to all defendants except Officer Miller, who was denied
qualified immunity. Officer Miller appealed and Rock cross-appealed. We have
jurisdiction under 28 U.S.C. § 1291 and the collateral order doctrine. Watkins v. City
of Oakland, 145 F.3d 1087, 1091 (9th Cir. 1998). We affirm.
We review de novo a district court’s grant or denial of qualified immunity. Id.

the U.S. Court of Appeals for the Fifth Circuit, sitting by designation.

at 1092; Tobias v. Arteaga, 996 F.3d 571, 579 (9th Cir. 2021). We take “the facts in
the light most favorable to the nonmoving party and draw all inferences in that
party’s favor.” Nehad v. Browder, 929 F.3d 1125, 1132 (9th Cir. 2019).
An officer is entitled to qualified immunity unless the plaintiff shows that
(1) the officer violated the plaintiff’s constitutional right and (2) the right was
“clearly established at the time of the officer’s actions.” Orn v. City of Tacoma, 949
F.3d 1167, 1174 (9th Cir. 2020). In conducting our analysis, we look to “cases
relevant to the situation [the officer] confronted, mindful that there need not be a
case directly on point.” A.K.H. ex rel. Landeros v. City of Tustin, 837 F.3d 1005,
1013 (9th Cir. 2016) (internal quotation marks and citations omitted).
1. We affirm the district court’s denial of qualified immunity to Officer
Miller, the canine handler, for allowing the dog to bite Rock for forty-one seconds
even though Rock was unarmed and not resisting arrest. 1 Our precedent clearly
establishes that allowing a canine bite to continue when the plaintiff neither
endangers officers nor attempts to flee or resist arrest violates the Fourth
Amendment. Watkins, 145 F.3d at 1090, 1093.
Here, police responded to a 911 call about Rock threatening his father’s wife
with a knife and damaging property. Upon arriving at the scene, officers saw Rock

We do not address whether the officers were permitted to deploy the canine
in the first instance because that issue is not before us in this appeal.

run and hide in a shed in the side yard. Before entering the yard, Officer Miller,
unaided by a PA system, twice warned that if Rock did not “make himself known,”
Miller would send his police dog into the yard to bite him. Rock, who was in a closed
shed on the opposite side of the yard, could not discern Miller’s words and was
unaware of the presence of a police dog. Miller eventually led the way from the gate
to the shed.
When he reached the shed, the canine signaled Rock’s presence to the officers.
The officers were immediately outside the shed but failed to provide additional
warnings about the dog. Cummings opened the shed door and Miller deployed the
canine into the shed. Miller gave a bite command and praised the dog for biting
Rock. Rock immediately began screaming in pain. The canine dragged Rock out of
the shed and onto his stomach, where four officers surrounded Rock. It was apparent
to the officers that Rock was unarmed and that the shed was empty. Indeed, Miller
admitted that Rock had nothing in his hands when he was dragged from the shed.
Defendants allege that Rock was resisting arrest by grabbing the dog’s lead but the
district court found a genuine issue of fact as to whether Rock was resisting arrest or
recoiling from the pain. See Armendariz v. Penman, 75 F.3d 1311, 1317 (9th Cir.
1996) (en banc) (“[T]he collateral order doctrine does not provide appellate
jurisdiction to review the district court’s decision that genuine issues of material fact
exist for trial.”), overruled in part on other grounds as recognized in Crown Point
4
Dev., Inc. v. City of Sun Valley, 506 F.3d 851, 852 (9th Cir. 2007). The bite lasted
forty-one seconds, resulting in serious damage to Rock’s arm.
Viewing the evidence in the light most favorable to Rock, Miller allowed the
canine to continue biting Rock even though he was unarmed, did not present an
immediate threat to the officers or others, and did not resist or actively evade arrest.
Watkins, 145 F.3d at 1093 (allowing canine to bite suspect for “excessive duration”
violated clearly established law); Mendoza v. Block, 27 F.3d 1357, 1362 (9th Cir.
1994) (observing that “excessive force has been used when a deputy sics a canine
on a handcuffed arrestee who has fully surrendered and is completely under
control”). Officer Miller is thus not entitled to qualified immunity.
2. Rock argues that the passive officers are also not entitled to qualified
immunity because: (1) they failed to intervene during the dog bite; and (2) they were
“integral participants” in Officer Miller’s use of excessive force. 2 Here, even
assuming a constitutional violation, we cannot say that the passive officers violated
clearly established law. “A right is clearly established when it is ‘sufficiently clear
that every reasonable official would have understood that what he is doing violates
that right.’” Rivas-Villegas v. Cortesluna, 595 U.S. 1, 5 (2021) (per curiam) (quoting
Mullenix v. Luna, 577 U.S. 7, 11 (2015) (per curiam)). While there need not be a
2
We do not address whether the passive officers failed to intervene or were
integral participants with respect to the initial deployment of the canine because
this issue is also not before us in this appeal.
5
Supreme Court or circuit case directly on point, “existing precedent must have
placed the statutory or constitutional question beyond debate.” Mullenix, 577 U.S.
at 12. Existing precedent does not place the question of the passive officers’
constitutional violations beyond debate. The passive officers are thus entitled to
qualified immunity on Rock’s Fourth Amendment claims arising from the passive
officers’ failure to intervene and “integral participation” during the forty-one-second
canine bite.
