Opinion

UNITED STATES DISTRICT COURT AT SEATTLE MARK E. TOWNER, CASE NO. 2:25-cv-00553-JNW Plaintiff, DISMISSAL ORDER v. A PLACE FOR ROVER INC., et al., Defendants. 1. INTRODUCTION This matter comes before the Court on Defendants’ various motions to dismiss. See Dkt. Nos. 58, 71, 73, 75, 111. Having reviewed the motions, Plaintiff Mark Towner’s responses, Dkt. Nos. 61, 64, 79–81, 112, the replies, Dkt. Nos. 91, 92, 98, the relevant record, all supporting materials, and the presentations made by the Parties at oral argument, Dkt. No. 107, the Court GRANTS the Motions. 2. BACKGROUND The operative complaint, Dkt. No. 12 (“SAC”), alleges as follows: Defendant A Place for Rover, Inc. (“Rover”), is an app-based platform where pet owners can connect with and book services from individuals interested in offering pet care services. SAC at 11. Through Rover, Towner arranged for his dog Bella to be boarded by Defendant Janis Cook at a house owned by her son—

Defendant Christopher Cook—in Chalmette, Louisiana. SAC at 10–12. When Towner arrived at Cook’s house on April 28, 2022, Janis Cook’s dog attacked Bella. SAC at 12. Towner was bitten on his left hand by Cook’s dog and fell to the ground while attempting to rescue Bella. Id. After repeatedly hitting Cook’s dog with his right hand, Towner was able to free Bella. Id. Towner then brought Bella to a veterinary emergency room for surgery where he filed a police report with

the St. Bernard Parish Sheriff’s Office and then opened a case with Defendant St. Bernard Parish Animal Control. Id. at 13. Approximately a year after the incident, Towner was diagnosed with “SLAC wrist” in his right wrist/hand, causing “ongoing pain due to [the] attack.” Id. Towner originally sued the Cooks, Rover, St. Bernard Parish Animal Control, and Amanda Forde in the United States District Court for the Eastern District of Louisiana. See Towner v. Cook et al., Case No. 2:23-cv-01597-SM-DPC (E.D. La.

filed May 12, 2023). Within months, he moved to voluntarily dismiss his case because his claims “present[ed] no question arising under the [C]onstitution,” and that there was not adequate diversity between the parties. See Dkt. No. 74, Ex. C. That case was dismissed without prejudice on July 10, 2023. See Dkt. No. 76, Ex. D. Nearly two years later, on March 24, 2025, Towner brought the instant lawsuit against the following Defendants: (1) Rover and its executives Aaron

Easterly, Brent Turner, and Charlie Wickers; (2) Christopher Cook; (3) Janis Cook; (4) St. Bernard Parish Animal Control and director Amanda Forde; and (5) Blackstone Inc.1 He brings seven discernible claims: (1) a personal injury claim against Defendants Janis and Christopher Cook; (2) a negligence claim against

“Each Defendant” for breaching their “duty to prevent [Cook’s dog] from inflicting bodily injury, and specifically against Rover for “illegally contracting with independent pet sitters,” and for not enforcing contractual obligations to “assure adequate safety for pets” or ensuring that those sitters maintain “adequate liability insurance”; (3) a negligence per se claim against Defendant St. Bernard Parish Animal Control for failing to maintain a dog bite database, follow rabies protocol,

and timely investigate the dog bite at issue; (4) another negligence claim against all Defendants as the “owners, lessors, managers[,] or control agency” of the Cook residence, each of whom violated a “duty to prevent injury to [Towner]”; (5) a premises liability claim; (6) a claim alleging that the venue provision contained in Rover’s terms of service is unconstitutional under the Seventh Amendment of the United States Constitution; and (7) a claim for “Intentional Negligence and Unconstitutional Use of Terms of Service to Avoid Liability And Laws.” SAC at 13–

23.2 Every Defendant has since moved to dismiss Towner’s claims. See Dkt. Nos. 58, 71, 73, 75, 111. The Court addresses Defendants’ various arguments below. 1 Towner also brought claims against various federal agency defendants but has since voluntarily dismissed those claims. See Dkt. Nos. 47–52. 2 Claims Six and Seven do not contain any discrete factual allegations about any constitutional violations. SAC at 19–23. Rather, they incorporate by reference all of the previous allegations in the complaint and then provide what appear to be broad, computer-generated summaries of certain areas of law. Id. 3. DISCUSSION 3.1 The Court does not have subject matter jurisdiction over this dispute. As a federal court, this Court must dismiss the case if it lacks jurisdiction. See Fed. R. Civ. P. 12(h)(3) (“Whenever it appears by suggestion of the parties or otherwise that the court lacks jurisdiction of the subject matter, the court shall dismiss the action”); see also Arbaugh v. Y&H Corp., 546 U.S. 500, 506–07 (2006) (“The objection that a federal court lacks subject-matter jurisdiction . . . may be raised by a party, or by a court on its own initiative, at any stage in the litigation[.]”). The Court concludes that it lacks subject matter jurisdiction here because (1) the parties are not completely diverse, and (2) Towner’s claims do not present a federal question. 3.1.1 Legal standard. Federal courts are courts of limited jurisdiction and are presumptively without jurisdiction over civil actions. Kokkonen v. Guardian Life Ins. Co. of Am., 511 U.S. 375, 377 (1994). Federal courts are presumed to lack subject matter jurisdiction over a case, and the plaintiff bears the burden of showing otherwise. Id. Broadly speaking, a federal district court has jurisdiction over all civil actions (1) “arising under the Constitution, laws, or treaties of the United States” (known as “federal question” jurisdiction), see 28 U.S.C. § 1331; or (2) for more than $75,000 where the citizenship of each plaintiff is different from that of each defendant (known as “diversity” jurisdiction), see 28 U.S.C. § 1332. See also Newtok Vill. v. Patrick, 21 F.4th 608, 615 (9th Cir. 2021). The party seeking the exercise of jurisdiction must allege sufficient facts in his complaint to establish jurisdiction. Fifty Assoc. v. Prudential Ins. Co. of Am., 446

F.2d 1187, 1190 (9th Cir. 1970). When a plaintiff represents themselves as a pro se litigant, their complaints must be “liberally construed” and held “to less stringent standards than formal pleadings drafted by lawyers.” Erickson v. Pardus, 551 U.S. 89, 94 (2007) (citations omitted). For example, pro se litigants are held to less stringent pleading standards for satisfying diversity jurisdiction. Mann v. City of Tucson, Dept. of Police, 782 F.2d 790, 794 (9th Cir. 1986).

Even so, “the court should not supply essential elements of the claim that were not initially pled.” Henderson v. Anderson, No. C19-789, 2019 WL 3996859, at *1 (W.D. Wash. Aug. 23, 2019) (quoting Bruns v. Nat’l Credit Union Admin., 122 F.3d 1251, 1257 (9th Cir. 1997)); see also Khalid v. Microsoft Corp., 409 F. Supp. 3d 1023, 1031 (W.D. Wash. 2019) (courts “should not have to serve as advocates for pro se litigants[,]” and a litigant proceeding pro se does so “with no greater rights than a litigant represented by a lawyer[.]”). “[I]t is axiomatic that pro se litigants,
