Ranchers often have to deal with wild animals that can be a threat to their livestock. Two of the most common enemies of ranchers are coyotes and pumas. Coyotes, which have six letters, are members of the dog family and are known for their howling. Pumas, which have four letters, are also known as cougars or mountain lions and are powerful predators. Both coyotes and pumas can cause significant damage to a rancher's livestock and property.
