Just curious if anyone has ever done it before, and what kind of dog kennel if they have, and how well it has worked for them. I saw one that's 6x10x6 for $200 both on Craigslist and Home Depot. I know that I will have to secure the bottom portion with hardware cloth (as well as put a skirt around the outside). I have a tarp I can put over the top, and /or even left over chicken wire (or leftover hardware cloth). I feel that maybe this may be a lot easier than constructing a run with 2x4's.
I also saw some dog runs that you can buy the individual 8x6ft panels, thought that might work too- in that case, I would only need two panels and I could sandwich my run in between the shed and coop.
