Dog House Idea for Cheap

I don't know how I ended up looking at craigslist Farm and Garden category, but anyway, I found an ad for 50 gal. plastic drums and part of the ads stated that they could be use as dog houses.  hmmmm.... what a great idea.  So I google barrel drums as dog houses and here is what I found.

 

Here are the drums I found.  the best part is they are only for $10 bucks each.  So I'm going to grab a couple or maybe more.
