Good morning! I've got a problem!!

My little Yorkie, who is almost nine months old, has taken up chewing on very small rocks/pebbles. Now, as most spoiled Yorkies do, she's got PLENTY of toys of various textures, sizes, shapes...but she still seems to have more fun playing with little rocks. I'm not sure if she would actually swallow the rocks because I think I get to her before she has a chance to do so. All her baby teeth have been pulled, so I don't think it is just a teething phase. I'm wondering if there's some kind of vitamin or something that she's not getting in her daily diet. We scold her every time we catch her and she rolls over on her back to calmly give up her prize, but I want to know if there is an underlying cause or is she just crazy!?

Thanks for your opinions!!
