Excessive eye mucus in Golden Retrievers is usually caused by factors such as internal heat, eye inflammation, and infectious diseases. The daily food of Golden Retrievers contains a large amount of oil or salt, which can cause the body to get angry and lead to an increase in eye secretions. It is recommended to adjust the Golden Retriever's diet structure and keep the food light.

Inflammation in the eyes of golden retrievers, such as conjunctivitis, etc., will also increase eye secretions. It is recommended to use pet-specific antibacterial and anti-inflammatory eye drops for treatment. Finally, Golden Retrievers suffering from infectious diseases such as canine distemper will also experience a temporary increase. It is recommended to consult a doctor for medication.
