our dorothy is the same at the moment..she is bald with a white glow..
after keeping weaners for years and never having an adult pig, it took us by surprise the first time dorothy moulted as she always had such a thick coat. when we asked the vet if it was normal, they didnt seem to know.
same with foals, they always seem to lose their face hair in the first few months, we asked a vet if that was normal or mites? and they didnt seem to know.
