I don't even kniw if its worth my trouble to answer someone so dumb that they didn't even read the rest of my comment. However, For your information. There is a difference between the body weight, and tracks of a domesticated dog, and a true coyote. Because of color phases, and the distance most people are from these critters, I don't rely much on size estimates. There is a strain of coyotes out of Kansas that is red in color, more rust red than true red like a fox.
The best way to identify whether you are dealing with a coyote, or a feral dog/coyote/cross, is to examine their tracks, or the feet of the dead animal. On a true coyote, the inner two toes on each foot will be small in size than the outer two toes. On a Feral dog/cross/coyote, ( coy-dog ), you will find it has the inner two toes LARGER than the outer two toes on the same foot, just like the domestic dog.
I have not been able to examine a lot of kill sites, but those I have examined involving livestock losses involve coy-dogs, or feral dogs doing the killing. Coyotes will come in and feed on the corpse, but it is usually the larger coy-dog that does the killing, unless the pack is running with a feral( wild) dog.
I do not take my observations as universal. I know too much about dog behavior to ever think that. I am sure that coyotes do kill dogs, cats, and livestock. My uncle acquired a cross between a german shepherd and a wolf, and it seemed to be okay. Certainly around the wife and kids. However, it got to wandering one night, and killed every chicken in the neighbor's chicken coop, eating none of them. My uncle found someone who lived many miles away on a large open ranch who would take the dog, and he paid the neighbor for his losses.
