Home remedies for a dog eye infection include a saline rinse, application of a chamomile teabag, and nutritional supplements. Serous conjunctivitis, a mild condition that causes the eye to look swollen and red and emit a clear, watery discharge, is the most likely infection to respond to home remedies.
To prepare a saline rinse, stir one-half teaspoon salt into a cup of warm purified mineral water until the salt is dissolved. Dip a cloth into the saline solution, and gently wipe the affected eye. Carefully use a cotton swab to remove any irritants that may be present. Repeat the process twice a day.
To treat an infection using chamomile, steep a chamomile teabag in a cup of boiled water for several minutes. Wait until the teabag cools, then place the teabag gently on the dog's eye. The liquid from the teabag can help prevent an infection from taking hold.
Certain dietary supplements can boost a dog's immune system, so its body is more likely to fight off infection. Vitamins C and A, as well as bioflavonoids, are key nutrients to include in a dog's diet and supplements.
Infections causing a discharge that includes mucus or pus require veterinary treatment. Antibiotic and corticosteroid eye ointments are likely to be prescribed to treat the infection.
