Our yard is being dug up for plumbing, not all of it though
We live in Portland, Oregon and have some grass and some moss and some grass struggling because dogs pee in the front yard. The backyard is lush with good grass. Is there somewhere we can have the earth tested from our front yard to see what fertilizer we might need and what type of grass seed to plant in late March, after the plumbing job is complete?

Establishing and caring for a healthy lawn is often more about proper fertilizing, mowing, and watering than specific needs regarding your soil. (If nothing can be done about the dogs, that limits your success.)
Here is a list of lawn articles published by the OSU Extension Service: http://extension.oregonstate.edu/gardening/tips?keys=lawn
"Envision the lawn you'd be happy with...." is a great article, with links to more complete publications: http://extension.oregonstate.edu/gardening/node/864
"How to minimize the impact of dog spots...." is another: http://extension.oregonstate.edu/gardening/how-minimize-impact-dog-spots-your-lawn
If you still want to test your soil, A&L Western Labs in Portland; contact them about prices, testing procedures, and what you can expect to learn from the results.
We will be reading the studies you provided and determine how to act.
