Shadowing DO and applying MD

I've been looking for doctors to shadow in my area. I found emails for a couple of DOs and was going to ask if I could shadow but I'm wondering, is it a bad idea to shadow DO if I plan to apply MD? I figured it wouldn't matter because a doctor is a doctor. But it looks like if you're applying DO, you're pretty much are required to shadow a DO. Is it like that with MD as well?
