My dogs lips on one side are swollen and red this morning. Thoughts of what this could be?

It could be a contact allergy where that side of his mouth came into contact with something caustic/irritating. I don't really know. If he seems otherwise fine you can try giving him some Benadryl - 50mg (2 tablets) every 8 to 12 hours for a day or so. If no improvement then you should have your vet check him out.
