I’ve had my Guinea pigs for about a month now and I’ve just noticed that one of them has a very dry and crusty ear. As a New Guinea pig mom I have no idea what could of caused this. Do you guys have any idea of what it could be/at home treatment to help his ear get better. Or do you think it’s something more serious which we should take him to the vet? Like I said I have multiple piggies so if this is caused by mites for example wouldn't my other pig get it too?
