We have two pugs one of which had sever conjuctivitis after a trip to the park. The poor thing had white creamy drainage from his eye and and one point could harldy open his eye. We are against antibiotics on less they are truly needed. We used a combinatin of ACV and colloidal silver. We wiped his eye with ACV on a cotton ball and then flushed his eye with colloidal silver using an eye dropper twice daily. We also cleaned his paw with ACV due to him rubbing his eye with his paw. He showed improvments in a day or two and by a week the infection was gone.
I starting using colloidal silver for pinkeye for our cats several years ago. It only takes a drop or two in the eye a couple of times, (not a day, just a couple of times total) and poof! the pinkeye will be gone. It's not any more painful than a drop of water would be. Also works great for humans! Just costs a fraction of what you would pay at the vet or doctor, plus you don't need to pay for a prescription.
Colloidial Silver is an awesome remedy for virtually any bacterial infection; internal or external. I have cured my dog's eye and ear irritations (and my pink eye) with a couple drops, the results were immediate. It comes in drops or spray and I have both. I spray my dog's cuts, sores, rashes and teeth because it does not sting. Antibiotics are inferior to Colloidial Silver, which was commonly used before antibiotics were popularized. It is found at health food and Meijer stores and is inexpensive for its many possible uses. Research it; you'll be glad you did.
