Sierra's teeth are perfect. I mean really, she's still young, but there isn't a mark on them. I was a bit surprised tonight when I was playing with her and noticed while she was on her back with her mouth open) these wierd black spots near her black teeth. It's on the roof of her mouth I guess, but right against the teeth. It didn't look *good* but she wouldn't let me take a better look, I kind of saw it by accident. Any ideas? Does this sound like something I should have a vet look at? Or could it just be unfortunatley coloured spots on the roof of her mouth like some dogs have? I know it's hard to get what I'm talking about when there's no pictures or anything, but hopefully someone will have some input.
