I think it looks odd. I would be nervous, so I would probably take her to the vet. But I dunno....I mean it could be nothing or it could be something. If its something I have nothing to offer that matches it in the way of symptoms. Maybe someone else will.....but again maybe nothing!??!!
Damn it sucks huh? I hate not knowing. I would call the vet/see the vet jsut for myself if anything else. Then you'll know and if it is "bad" you will have hopefully caught it in time to do some good.
Good luck Andy G!
