You definitely don't want to put any solution in the eye that isn't designed for eyes. Peroxide should not be instilled in any eye. Mild conjunctivitis of the eyes is usually self-limiting and will go away on its own. You can clean eye discharge with warm water and a soft cloth. If your dog is squinting, seems painful, scratching at his eyes, or if the corneal surface of the eye seems blue or cloudy, he may have a scratched cornea or other more serious eye condition and needs to be seen by a vet right away. If the eye seems to have yellow or green discharge for more than 48 hours, you may need a vet visit to get some antibiotic eye ointment to start him on.

    I would not recommend to put either of those in Henry's eyes. Even the water may cause burning and discomfort. Conjunctivitis is most commonly caused by allergies, infections or corneal ulcers. Take him to the vet to have him examined and appropriate treatment can be prescribed.
