They will take down cows, IF the chance presents its self. Large/ medium size cow . Was jumped by large pack of coyotes. Cow was laying down in tall grass, coyotes attach in force, because of grass and terrain cow can get up, gets eaten alive. Its a horrable thing to see, but does happen. Also lots of times a cow has a hard time with delevery of calve so its week lays down and coyotes get it. So i guess you can say theirs< points on the board for both our ways of the arguement> i quess.
