If your dog has keratitis, you can use anti-inflammatory and bactericidal eye drops, such as Wangxiang eye drops, Fengge eye drops, etc. It is best to use dog-specific eye drops to reduce irritation and damage to the eyes. When a dog suffers from keratitis, you need to first use saline to clean the dog's eye secretions to act as an anti-inflammatory, and then apply eye drops to the dog on time to keep the environment clean and hygienic to avoid infection or aggravation of the condition.
