Yesterday I noticed my little female piggie, Rose, has an infected looking eye. The front corner is swollen & red, and she's got some crusties at each corner (front and back). It's only her left eye that is like this. Otherwise than her eye, she seems to be perfectly fine. She's eating normally, etc. What can I do for her? I've been wiping her eye every day with a warm damp cloth. Is there something I can put in it? I have Terramycin Antibiotic Ophthalmic Ointment with Polymyxin B Sulfate. It's made for dogs and I'm not sure if it's safe for use on piggies. What do you think might have caused this? She roots around alot in her bedding/hay and both are dusty. Thank you for your help!
