Dog Friendly Hiking

Hello! I’m considering a move to Seattle later this year. I am very outdoorsy, and I have a well mannered dog who I’d like to bring hiking. I understand the impact pets can have on wildlife, etc. and am not trying to argue about that, just looking for central information regarding which parks/hiking within a few hours of Seattle are dog friendly and which are not. It seems to be pretty 50/50 from the individual places I’ve googled.

Thanks!
