There seems to have been a run on copies of Dog Culture this week, thanks to the review in The Week. So if you are looking for a copy, here's what I can tell you:
Amazon: Sold out of new copies of both the paperback and the hardcover; a few used copies available, plenty of used paperbacks.
Barnes and Noble: Sold out of the hardcover; some new paperbacks still available.
Powells: three paperbacks left; sold out of all hardbacks and all used copies.
Strand: four used hardcovers available this morning.
If you live in New Orleans: copies are available at Beth's Books next to Sound Cafe.
