Some dogs give Coyotes that work. For example:
"Casper
Casper, a 21-month-old Great Pyrenees, soon led a counterattack and hopped a four-foot fence. Over the next several minutes, Wierwille said Casper killed eight of the 11 coyotes on his property and chased away the rest. The five sheep remained unharmed."
Also A pitbull killed 9 Coyotes, coming out of it needing some stitches. The owner found the bodies by following his dogs drops of blood back to the Slaughtered Coyotes.
The Alpha Coyote, after seeing 9 of his comrades dying on the grass, asked, "Who are you!?"
The Pitbull responds, "They call me Princess Cupcake."
