This morning at agility class one of the dogs had an eye infection. Sidney's owner did a good job of keeping her away from everyone else, but this afternoon I noticed that Phebe is squinting with her blue eye has a bit of discharge. I have some oral antibiotic left from a couple of weeks ago, cephelexin (sp?). Should I give it to her? Can I rinse her eye out with saline or epsom salts? I don't want to go to the vet on the weekend.
