The coyotes by my house are really big. I shot a small female and she was probanly 45-50 pounds and she was the smallest one I have seen. I had a picture but it was on my phone which went out. although I have her skull.I don't want to make inflated claims but our yotes being as big as wolfs but they are big. I have three 100 pound plus dogs and the yotes are smaller than them but I would say they look like german shepards. I almost wonder if they are hybrids. How big do yotes get in illinois. They have a ton of cats and rabbits to eat and we also have alot of deer so I know they eat good. Maybe they just look big cause of the fur.
