PDFWAC 162-26-130
Use of trained dog guide or service animal.
(1) Coverage of statute. RCW 49.60.215 requires fair service in a place of public accommodation "regardless of . . . the use of a trained dog guide or service animal by a disabled person . . ." as well as because of disability itself.
(2) Same rules apply. All of the rules of this chapter with respect to disability itself apply equally to service of a person with a disability who is using a trained dog guide or service animal. See particularly WAC 162-26-060 and 162-26-070.
