Without seeing your dog in person or a better view of the eye it is hard to say for certain but this could be severe conjunctivitis/episcleritis (inflammation due often to infection, sometimes to dry eye/decreased tear production) or a subconjunctival hemorrhage (bleeding under the conjunctiva) which can be due to to trauma or a bleeding disorder or high blood pressure. A veterinary exam is needed to pinpoint the problem and prescribe appropriate treatment.
