I agree with wackyquacker, no specifice attractor i've ever used would elicit a defication response consistently. Like Wacky, i've had coyotes occasionally leave a turd at sets that were lured with gland lures, food lures, curiosity lures urine/gland lures and plain urine. The sets were hole sets, blind sets and post sets. With all due respect to Mr Dobbins, unless the testing was done at mock sets with no trap, few canines would survive a well placed and well guided set long enough to know how many might leave their marking.
