Here's an old thread on how I did mine. They've been complete for almost a year and there's nothing really I would change. My favorite part is the septic system...had people tell me it wouldn't work but as much poop as I put down that thing if it was going to have a problem it would have before now! Since building it, I've housed on average 12 - 15 dogs.
Only thing about concrete floors, is daily washing is a must. It takes me about 45 min, and three cold beverages an afternoon to wash and feed.
