banana, pb, frozen blueberries cut in half, apple (small bites, skin removed), all natural apple sauce, green beans, peas, bits of plain cooked chicken, kibble, cooked carrot, pumpkin...I usually just choose about three of the above depending on what I have on hand, and I often freeze them so they last her longer
In general too, little pieces of frozen banana are Maggies very favorite treat! I use them for a reward after potty.
