It's a long story how Theo, my little cocker spaniel, lost his right eye the day after Thanksgiving. By the time we realized something was wrong, he had already managed to scratch both eyes, most likely by rooting beneath some newly planted trees in his yard.
When we noticed he was squinting, we took him to the vet and brought him home with eye drops. And then he bumped into a chair. He yelped, appeared to be in great pain, and so we flew back to the vet. The eye could not be saved, and so we made the heartbreaking decision to have it removed.
Dogs are troupers. Everyone will tell you this when yours suffers a trauma, and it's true.
