Does she have allergies? Has she been rubbing her face up against furniture or anything?
Mo has allergies and his fur is very thin around his left eye, but he rubs his face along side of the bed, couch, etc. He's basically rubbed the fur right off :

He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
I had a Springer that had the same thing (his looked much worse tho). I took him to the Vet and she told me he has some kind of mites. She gave my eye drops and he was put on steriods for a short time. The steriods were a bust. They make them very thirsty so he was drinking piles of water, then peeing on the floor! If you are concerned about it, I would think a trip to the Vet is in order.
