Suggestions for Easy Hikes Near Seattle

Hello! I have never been to Washington state, and I am very excited to be able to visit this summer for a dog sitting gig. I will have access to a car, and the dog is a 13-year-old senior lab who has a little bit of arthritis. His owner says he loves to go for hikes as long as they are not strenuous or too long (coincidentally, my preferences match his haha).

I am interested in suggestions for hikes that are:
*easy to moderate
*can be completed in about 1 to 1.5 hours
*are located within about an hour of Seattle

I found a couple on Alltrails that look nice, such as:
**Snoqualmie Falls Trail
**Gold Creek Pond Loop

Would love any other suggestions (or if you have been to the ones mentioned above, did you like them?). Thanks!
