One hundred eighty dogs were studied to determine if breed affected food preference. of the 70 huskies, 30 preferred beef flavor and 40 preferred chicken. of the 50 poodles, 27 preferred beef, the rest chicken. the rest of the dogs, english mastiffs, were obviously beef-lovers, as only 19 preferred chicken over beef.
