It's understandable why you're thinking it may not have been a coyote. I've learned that coyote scat can vary by time of year and region. Here with toyon and manzanita berries, the scat can be berry infused and very dark and less dog like. That's often what I see. So I looked up some photos and sure enough lots of coyote scat does look like his photo.Just a guess based on coyote scat I've seen. Not just the hair factor, it just doesn't look right to me based on my experiences. I could be wrong. Wild animal scat of any sort can vary greatly depending what they've recently consumed. As others have said, size of scat makes a huge difference, and I don't know that piece of the puzzle either.
I forgot to post this earlier... it's very similar to the chart in Storey's guide as well. This may help OP figure things out with other clues.

And so does cougar scat. Yikes. But I'm not familiar with the wildlife in Alabama.
