To be completely honest I would wait... Oakley hasn't quite hit adolescence yet and when he does, it will be like having a furry hurricane in the house. During the "teenager" stage, they seem to forget everything you've taught them, and can be very frustrating to handle. A month after getting your first dog is a little soon to be getting your second. I would wait till Oakley turns about a year old... long wait, I know, but it may be worth it not to have two large teenage dogs to train.
