It will take about a week for dogs with mild symptoms of keratitis to recover. If the symptoms are more severe, it will take about a month. This needs to be judged based on the condition of the dog. If a dog has keratitis, it must be treated promptly. Help the dog clean foreign objects in the eyes, use anti-inflammatory eye drops on time, pay attention to keeping the environment clean and hygienic, and try to avoid taking the dog to dirty places. ,
