It may be that the dog suffers from conjunctivitis or keratitis, accompanied by redness, swelling, tears, and pain when exposed to light. It may also be caused by foreign matter entering the dog's eyes and the dog scratching it himself. There may also be symptoms such as eye redness and ulcers, and inflammation may be caused by bacterial infection.

Tip:

The owner can put an Elizabethan ring on the dog to prevent the dog from scratching, and then use a pet-specific eyewash to clean the dog's eyes, and then Give your dog special eye drops for dogs. If the condition does not improve for a long time, or if it becomes more serious, it is recommended to take the dog to a pet hospital for examination and treatment.
