Last night I noticed a scab on the face of one of my daughters guinea pigs.i have been looking on the Internet for advice but I'm not really getting anywhere.she does have an appointment at the vets tomorrow as they are closed today and it's not an emergency but I'm feeling lost and confused as to how this could of happened. I do think it's some sort of bacterial thing or mites but I've checked the rest of her body and see nothing except a new scab on the other side of her face today.could this be ringworm and is there anything I can do just now to ease her discomfort from it.if this is ring worm I am going to have to treat my other two pigs as they all live together.any advise would be great and appreciated thankyou x
