The dog's eyes may be swollen due to inflammation, allergies, or parasite bites. Parents can clean the dog's eyes, apply some eye drops, and take the dog to a ventilated place. Generally, it will not last for a few days. It will get better soon. If its eyes are not good for a long time, parents should take it to the hospital for treatment.

Tip:

In the summer when there are many parasites, parents should increase the frequency of deworming, and usually help dogs drive away mosquitoes to avoid being bitten.
