That is a good size coyote! I have a pic of one on my website
http://www.brendajacobsphotography.com under Galleries/Wildlife that took down a deer on my property. There was actually two of them but not in the pic. When I first saw them I thought they were German Shepherds because of their size. Then I did some reading up on eastern coyotes. Basically exactly what you posted above.
All the more reason not to leave your small even medium size pets outside alone.
