The best thing I know to use is Spectromast --which is use for teat infusions in dairy cows, but you can use it as a topical treatment for Pinkeye---
Another treatment which is Organic:
Get your vet to pull some blood from your pinkeye victim to be centrifuged He will also need to get some fluid from the infected eye. This blood serum along with the fluid from the infected eye can be used as a topical treatment for Pink eye. works great
