Cool experiment. When you talked about the dog… it reminded me of when I had my dog Brandy, she used to eat slices of oranges which I thought was odd. I only let her eat that a few times though. She loved onions and tomatoes also. She lived to be almost 16 years old. I miss all 3 of my dogs. 💔 😢. Have a Great Day Everyone. ✌🏻❤️👩🏻🦱
