Coyotes are very dangerous. They usually do not allow you to get that close to them. The problem is if the coyote has rabies or is sick in any other way they will be very aggresive and come after you. I am not sure what you should do if confronted again.
The wolf is larger and an aggressive hunter and is more group oriented. The coyote is somewhat group oriented, but is more of a scavenger. The wolf is larger, the coyote is smaller and has a pointier nose and is a dull brown color.The wolf can be white, black, gray or anywhere in between. work at an airport where we get Coyotes on the Runway very often... I have wondered what the difference was myself.... here's what I found :) The coyote (Canis latrans, meaning barking dog) also prairie wolf) is a member of the Canidae (dog) family and a close relative of the Gray Wolf.
