Maybe It's Poison

Every morning after breakfast, Emme comes upstairs with me to my sewing room when I check my email. I always give her a sweet potato treat after we enter the room. I buy the "Bichon Fries" which are cut like crinkle cut french fries. I break them in half so she gets a piece about two to three inches long. She has just recently finished breakfast so she doesn't need a huge chunk of sweet potato. Although I have been doing this for months, every time I give her a sweet potato treat, she backs up and smells it like it might be poison. You think she would remember from day to day that the treat is wholesome and that she likes it. Instead, she has to sniff it suspiciously each time before she take it from me.
