Snohomish County's website describes the rule simply: dogs must be leashed when off the owner's premises. That shorthand is close enough for a pet owner. For someone who has just been attacked, the code text is more useful, because it does not turn on whether a leash was clipped on.
Where the rule applies
Chapter 9.14 SCC is the county's dog leash law, and it governs unincorporated Snohomish County. The county code defines "county," for purposes of its animal title, as the unincorporated areas. Everett, Lynnwood, Bothell, Marysville, Edmonds and the rest have their own municipal codes, and citing the county section for an incident inside a city is simply the wrong law.

What SCC 9.14.030 actually requires
SCC 9.14.030 makes it unlawful for the owner or custodian of a dog to cause, permit or allow the dog to roam, run, stray or be away from the owner's or custodian's premises, or to be in any public place or on public property, unless the dog is under control. The section exempts dogs directly supervised by their owners while using designated off-leash areas on county park property. A dog found away from those premises and not under control is declared a public nuisance and may be seized and impounded.
Note who the rule reaches. It applies to the owner or custodian, which means a dog walker, a house sitter or a family member holding the leash falls within it.
"Under control" is a defined term, and the definition matters
The county defines "under control" in SCC 9.01.030 as the dog being restrained by a secure leash or other restraint not more than eight feet in length, and under the physical control of a person capable of restricting the animal's movement while off the owner's premises.
Two things follow that people miss.
First, a leash alone is not enough. A twenty-five-foot retractable lead is a leash, and it is not eight feet. Neither is a leash held by someone who cannot physically manage the dog on the other end of it. The code asks about restraint length and actual physical control together.
Second, and more useful after an attack, the same definition adds a presumption. A dog is presumed not to be under control if it chases or approaches a human or domestic animal in a menacing fashion or apparent attitude of attack, or if injuries, damages or trespass result. Read that carefully. The conduct that hurt you is itself capable of establishing that the dog was not under control, without anyone having to prove where the leash was.
The chapter does carry exceptions. Under SCC 9.14.040, the prohibition does not reach dogs that are under control while engaged in lawful herding, lawful hunting, sanctioned competition, or training for those activities, and it does not reach search-and-rescue dogs operating under the applicable state rules or dogs engaged in law enforcement activities. Each of those still presumes the dog is under control.
A leash violation is evidence, not automatic negligence
This needs saying directly, because the shorthand circulating in Washington personal injury writing is wrong, and some of it has appeared on this site.
Under RCW 5.40.050, a breach of a duty imposed by statute, ordinance or administrative rule shall not be considered negligence per se, but may be considered by the trier of fact as evidence of negligence. The statute preserves negligence per se for a short, specific list: electrical fire safety, the use of smoke alarms, certain sterilization requirements for body art and piercing, and driving under the influence. Leash rules are not on it.
So a violation of SCC 9.14.030 does not decide a negligence case by itself. It is evidence a trier of fact may weigh. Anyone telling an injured person that an off-leash dog means automatic liability is overselling, and that oversell tends to get corrected at the worst possible moment.
Why the analysis splits for a bite and for a collision
For an actual bite, the leash question is not the center of the case at all.
RCW 16.08.040 makes the owner of a dog liable for damages when the dog bites a person who is in a public place or lawfully on private property, regardless of the dog's former viciousness or the owner's knowledge of it. There is no leash element in the statute. A dog can be perfectly leashed and its owner still liable for a bite.
For a non-bite injury, a knockdown, a collision on a trail, a fall while backing away, the statute does not reach the conduct and the claim proceeds under ordinary negligence. That is where the leash rule does its work, as evidence of a failure to exercise reasonable care rather than as an automatic finding.
How off-leash evidence still helps
Downgrading it from "automatic" does not make it unimportant. In practice it tends to matter in three ways: it supports the county's own presumption that the dog was not under control, it bears on what a reasonable owner in that setting should have done, and it frequently produces an animal-control file that documents the incident independently of either side.
What to document at the scene
- Whether the dog was restrained at all, and if so, with what. Photograph the leash if you can do it safely.
- Roughly how much line was out, and whether the handler could physically manage the dog.
- Who was handling the dog, since the rule reaches custodians as well as owners.
- Exactly where it happened, including whether you were inside a designated off-leash area on county park property.
- Witness names and phone numbers.
- Photographs of the injury and the location.
Then report it. In unincorporated Snohomish County, Animal Services takes bite and attack reports at 425-388-3440 or through its online complaint form, and it investigates leash-rule complaints as well.
