Duke has introduced a dog proof trap. It is a replica of the Lil' Griz trap. These traps are fast and effective.
They work extremely well with sheep wool or cotton ball underneath the trigger and Coon Kicker Lure. Just set and push trap stake into ground the traps sits up which also attracks those coons. Be sure to stake the trap chain.
Buy each or by the doz.
[I have a limited number of these due to Duke shortage!]
