Hey Sassy,
If she's pregnant the father would be Tuck, Roll or the White Mosaic she was caged with.
As for her ears I don't think it's dust - it's black and yucky!! Keep in mind the first time she had a
dust bath was when I got her. These chins were kept in horribly dirty conditions. I have held out on a water bath as a last resort but I'm not sure I have much choice - her fur looks horrible and no matter how many times I let her dust bathe, she comes out looking as bad as she did going in... I will try the solution on her ears. Thanks.
