What to Do When Your Dog’s Eye Is Swollen
📝 Summary
A swollen dog eye can stem from a foreign object, heat, injury, blocked tear ducts, infection, or allergies. Flush out debris, adjust diet, use vet-approved eye drops, and see a veterinarian if it doesn't improve or an allergy is suspected.
1 Common Causes and Treatments for a Swollen Dog Eye
1. Foreign-object irritation
If only one eye is red and swollen, a foreign object is likely the cause. Use a cotton swab to remove it or apply pet eye drops to flush it out; the swelling should subside in a few days.
2. Heat / internal imbalance
Swelling can also come from ‘heat’—usually from overly dry or salty food and too little water. Adjust the diet, stop sharing human food, and encourage drinking to flush toxins.
3. Injury
Playful dogs may bump an eye or get scratched by a companion. If it’s only swelling with no other symptoms, apply pet antibiotic eye drops; if it persists after a few days, see a vet.
4. Dacryoadenitis (tear-duct inflammation)
Swelling can result from infected tear glands that cause constant tearing and redness. Have a vet examine and prescribe medication, then follow the instructions.
5. Bacterial infection
An infected eye becomes red, swollen, with crusty discharge. Use antibiotic eye drops; if there’s no improvement, go to the vet.
6. Allergies
Dogs get allergies too, often from environment or diet, which can swell the eyes. Don’t self-medicate—have a vet identify the allergen and give an anti-allergy shot to prevent recurrence.
