This morning she had a more solid poop and waited to pee until we went outside so that is really good. And she is acting more like her old crazy self. I just gave her a little bit of her freeze dried stella & chewy with some canned pumpkin, but will continue to keep food light for the next day or so. She has an iron stomach, so it must have been really nasty :/ And will definitely update if anything changes, but she seems to be ok. Such a survivor, this tiny 6lb dog! It's amazing how resiliant, tough, and fearless they are!
And yes, it's awful that people would put things in a dog park to make dogs sick. It's hard for me to begin to understand how someone could do that. In this case, I live in SF, and there are a lot of drug addicts and homeless people who will leave their old food and whatever else in public parks and spaces.
