Can my dog get rabies from a dead animal?

I was playing fetch with my yorkie this morning and the ball rolled down a hill behind our shed. I waited for my dog to come back to me with the ball but she didn't so I went to see what she was doing. I saw her rolling around on the ground (like she usually does when she finds something smelly) next to what looked like a dead squirrel or rabit. At the quick glance I took I saw it was rotting and opened up, not just laying dead. So if my dog came in contact with the insides of a wild animal, is there a chance she could get rabies? ALSO the inside of her lower left eyelid is red and puffy. this just came up today as far as I've seen. She always has sties and goobers in her eyes though. The vet has never mentioned anything about it at a check up. She has gotten this red puffy thing on her eye before but usually passes within a week or two. But the fact that it just popped up today after the animal incident has me freaking out! Should I take her to the vet?
