(1) Any dog that is restrained outside by a tether must only be restrained for a period of time that is not reckless and in compliance with this section.
(a) The dog shall not be tethered in a manner that results, or could reasonably result, in the dog becoming frequently entangled on the restraint or another object.
(b) If there are multiple dogs tethered, each dog must be on a separate tether and not secured to the same fixed point.

(g) A dog shall not be tethered by means of a choke, pinch, slip, halter, or prong-type collar, or by any means other than with a properly fitted buckle-type collar or harness that provides enough room between the collar or harness and the dog’s throat to allow normal breathing and swallowing.

(i) The dog shall not be tethered in a manner that causes the dog injury or pain.

(a) A first offense shall result in a correction warning being issued requiring the offense to be corrected by the person who owns, keeps, or controls the dog within seven days after the date of the 40 warning being issued in lieu of an infraction unless the offense poses an imminent risk to the health or safety of the dog or the dog has been injured as a result of the offense.

(c) A third or subsequent offense is a class 1 civil infraction under RCW 7.80.120(1)(a).
