It's most likely an ear infection. If you see dried blood caked around it's probable pretty severe. This is one of those cases where going to the emergency vet is borderline. It's really up to you. He's certainly not in any life threatening situation at all. It's really about his comfort. You know your dog. I am sure that his ear hurts. There is not anything over the counter you can safely give him tonight for pain. I know some people give asparin, but I recommend you don't. It has a very high rate of causing GI bleeding in dogs, and it will interfere with the pain meds your vet will give you when you take him in. At any rate, you won't be wrong whatever you decide to do. Watch his behavior, if he's really pawing/scratching or moping around--you might want to take him tonight.

Good Luck,
