I don't know about washington but many other states have search and rescue courses for people and for dogs that would involve wilderness first aid and mountain climbing rescue. do a google search. I think the certification is the way to go, however
I know in colorado some community colleges have course you can take without get a degree. going to college isn't anything like high school, and if you only have to go for a couple of days or a few weeks.
it wouldn't be that bad.
you may want to contact a college or university they will have information about what your looking for or they can tell you were to look and who to talk to.
