DOG-FRIENDLY PARKS IN LAKE OSWEGO, OR

Willamette River borders Lake Oswego's eastern edge, where 40,000 residents occupy hilly terrain south of Portland. Marine west coast climate means cool summers near 80°F and mild winters averaging 42°F, with annual rainfall exceeding 45 inches. Oswego Lake—a 405-acre private lake—defines the city's center, while neighborhoods climb surrounding hillsides with elevation changes approaching 500 feet.
