Earlier today, Moxie was at the park and ate some nasty old food on the ground before I could stop her. She seemed fine but has been gassy and later had diarrhea. She has seemed mostly normal but just peed on my bed and was basically sitting right next to it until i noticed the smell. This is highly abnormal and worrisome. Is that a symptom of something? Should I observe her or take to vet? I don't know what what in that yucky food on the ground
