Please help. My little 5 1/2 pound yorkie at a Mrs. Fields oatmeal raisin cookie. My the time I found her she had eaten almost the entire thing. It was in my trash can in my room open which someone she got into. I do not know what to do, or what I should look for. I do not know how many raisins were in the stupid cookie. Please some advice is very much needed right now as I am trying not to completely panic.
