Whether a dog’s injured and congested eyes can heal itself depends on the extent of the injury and the timeliness of treatment. If it is just a minor scratch or the conjunctiva is slightly damaged, the dog may be able to heal itself by relying on its own immunity. However, if the injury is serious, such as severe eye congestion, it may cause the dog's retina to detach, eventually forming irreversible lesions that cannot heal on their own.

If your dog's eyes are injured and bloodshot, you need to take immediate action. First of all, you need to use drugs that are antibacterial and anti-inflammatory, help capillary convergence, and promote the absorption of congestion. At the same time, it is recommended that you take your dog to a pet hospital in time for eye hemostasis and anti-inflammatory treatment. If necessary, you also need to have your dog receive a professional eye examination to see if the eye structure is damaged.
