It is normal for a golden retriever to have red film on the corners of its eyes, and it will be fine if it does not affect vision. If the symptoms appear suddenly, you need to go to the hospital for examination immediately. Generally, the red film under the golden retriever's eyes may be caused by internal heat. You can apply some anti-inflammatory eye drops and pay attention to the dog's diet and hygiene. If the red film is severe and affects the dog's vision, it may be caused by bacterial infection or trauma and foreign objects. You need to go to the pet hospital for examination and timely treatment to avoid serious situations.
