Thanks for all the info. I hope she grows out of it. At least I am not the only one.
She has been responding well to "drop it" for my kids toys so I try that and she runs with a mouth full!
My bigger dog (Zoe) goes after cat poop but never her own. She isn't as bad anymore with the cat poop and I learned early on to keep on top of the cat box to curb that one.
