Man is a predator with eyes looking straight at his prey and he has a companion predator at his side, the dog. Together they make a formidable team and the hunted had better be wary.
Prior to the 19th Century, man hunted for food. Along with his dog and rifle, bow and arrow or spear the number of animals killed were of no consequence to their population. At the end of the century man began killing to control other human cultures thus hunting a species to the brink of extinction; i.e.: the American Bison.
Today animals are poached for various reasons leaving their carcasses to rot in the sun. Hunters wound animals and do not pursue them to be sure they have been killed. . It is not unusual for Greyhounds to be placed in boxes on the back of trucks and released while moving at speeds up to 35 miles per hour to hunt coyotes. These unethical practices are not the norm. Ethical people are usually ethical hunters with dogs that have been trained properly.
Some hunting dogs are harshly trained by the use of shock collars and over discipline. Most hunting dogs are trained gently making them good hunting companions for their owners.
Wisconsin hunters use their dogs not only to hunt birds, but deer, wolf and bear.
