Without a picture it is hard to tell what it is, but large breed dogs can get a hygroma at the elbow. It is often due to hitting their elbows or constantly laying on that side as a result of constant pressure. It may be a tumor of some sort also. Your vet can aspirate the swollen area to distinguish what it is to see if further treatment is needed
