Sam loves Cannon Beach, Oregon. Most of the stores there are dog friendly so he can go in them (plus most of them have treats!) and of course, his favorite part is the beach. He gets so excited he spins in circles when we go to the beach.
Locally, we live a five minute walk from the dog park so we go there a lot, and there's some hiking trails that are great for off-leash stuff since barely anyone goes there. Then we usually walk back to the baseball fields and the playground, and there's a mini-waterpark where dogs are allowed as well, but they have to be on-leash. That's all withint 20 minutes from my house so we go to these places a lot.
This summer he's going camping with us at Blue Lake, Lake Chelan, and Yellowstone National Park. SO I'm sure we'll find new places then!
