It was 87 degrees here - YES! Believe it or not in OHIO! Well, my pen is starting to stink and attract flies. Definitely can't have that so please tell me how to fix it. My pen is a dog pen, 10x10x6 and it's just in the grass. Well, it was grass and now it's mud. I just put some straw down before I took these pics hoping it would help: Thoughts?
