It may be that the owner feeds the dog food that is too dry, or keeps feeding high-calorie food, and does not pay attention to whether the dog lacks drinking water, which causes the dog to get angry, cause eye inflammation, and finally pimples will appear in the corners of the eyes. It is recommended to adjust your dog's diet to ensure adequate hydration and consider switching to a healthier dog food.

If there are small bumps on the corners of the dog's eyes and chinchillas, then this may be nictitating membrane gland hyperplasia, or Known as canine third eyelid ectropion. This may be caused by congenital genetics, eye disease or systemic autonomic nervous system abnormalities. At this time, you need to consult a professional pet doctor.
