Dog Eye Infections

I think my dog has en eye infection. I was playing with my pit bull Charlie in the park over the weekend when I noticed he began scratching at his eyes. They seemed more red than normal and the dog eye pink, and the eyelids looked a bit swollen. Besides pawing at his eye area, he was squinting when the sun was directly on him. I got some water to wash them out, but they still appeared to bother Charlie. It’s possible that my dog got an eye infection as he doesn’t normally experience any allergies. I researched treatment methods and found out I should see a Vet who may prescribe some antibiotic eye ointment. I am also looking in to taking some preventative measures such as supplements to aid in limiting the chance of any eye infection occurrence.
