Hey. The condition looks severe. Looks like there’s heavy discharge from both the eyes. Use Opthocare KT drops, put one drop each to both the eyes. 3 to 4 times a day for next 7 days.
Plus deworm him. Use Syrup Nemocid ( 0.2ml-0-0), repeat after 21 days. But looking at pet’s condition I suggest you to book a home consultation with a veterinarian to get him examined thoroughly.
