i havent really used much "people" food to train pebbles. i buy really soft, tiny liver treats and petco cookies (they look like human cookies). I have to break both into really tiny pieces. Ive tried giving her cheese but she just spits it out. her favorite are the animal crackers from petco
oh! once I gave her a piece of strawberry... haha it was so funny to watch her. she had no idea how to eat it. she just kept licking it. she took it from place to place all day and sucked on it like a lolly
