Reasons for a sudden increase in eye mucus in dogs:

1. It may be a viral infection, such as canine distemper virus, and the dog’s eye secretions will increase.

2. It may be that the nasolacrimal duct is blocked, especially for dogs with short noses. The nasolacrimal duct is blocked and eye secretions can only flow out through the corners of the eyes and accumulate into eye feces.

3. It may be caused by eye inflammation, such as conjunctivitis, blepharitis, eyelid entropion, etc., and excessive tearing may lead to excessive eye feces.

4. It may be that eating high-sugar and high-salt foods or a large amount of animal offal causes the dog to shed more tears and form eye feces.

5. It is also possible that there is trichiasis or foreign objects in the eyes, causing the eyes to shed too many tears and form eye feces.

Solutions to the sudden increase in dog eye mucus:

1. The owner should promptly check whether there are foreign objects in the dog’s eyes and help clean them up.

2. If it is caused by internal heat, the dog’s diet should be controlled reasonably and light food should be fed.

3. If it is caused by canine distemper and other diseases, you need to take the dog to the hospital for further examination and treatment.

4. If it is caused by eye inflammation, you can buy special eye drops for dogs to treat inflammation.
