I'm looking for honest answers, and hoping for no flaming.
I'm feeling quite guilty lately about the amount of exercise Cherokee gets. We have a decent sized yard she has free run of, and I try to have a pretty fast paced play session every day. She also gets walks, but not every day, and only 20 or 25 minutes each.
It's hard for me because she's quite reactive, which we're working on, but I don't know how to get her enough exercise while working around her reactivity.
If she wasn't so reactive, I'd take her to the dog park that's 

ractically 10 feet from my house, and the dog beach, and I'd walk her WAY more, but as it is, I don't know what to do.
Any suggestions? How much exercise does YOUR dog get?
