Just the snout seems short and the head small, but if it's 100lbs, obviously I am pretty wrong.If you would mistake the 100 lb timber wolf pictured above for a coyote, look at the proportions. VERY different. Tail and ear size in comparison to body, depth of chest, etc. Colour is similar but irrelevant. It becomes obvious with some practise.
