Hazelia Field is a great dog park in Lake Oswego off of Overlook Drive and Stafford road. It is very highly rated on fetch.com and Portland pooch! It is fenced and has a great area for the dogs and their people!

We would not be able to reserve it as it's owned by the city of Lake Oswego but I think that it would be a great spot to have a June Romp. Is the weekend of June 27-28 a good one for most people? Does Saturday or Sunday work better for you?
Sunday would work for us. Saturday has to much on the plate. Bella would be happy to see her doodle friends. She has a blast every time we got together.
