Well, curiosity got the better of me. The other night I shot a big old female coyote and by the time I got her dragged out of the valley some 300 yards I would have sworn she weighed 100 lbs.
Anyway, I got out the beam scale and weighed the carcass - 32 lbs all skinned out. I fleshed at least 4 lbs of fat from the hide - I think she must have been close to 40 lbs live weight. On the stretcher board she measures 63" from nose to end of tail hairs and 13" wide at the bottom.
I took one dog that I am sure was bigger than her, but the tape measure shows 63 and 13 for him as well.
