askm "whats it worth to you for it to be gone" then step back and wait for them to set the price, if they hit to low just turn and SLOWLY walk towards your truck never saying a thing and they will hit you where you want 10% sounds fair at this time

,,also
check the houses in the surrounding area see if anyone has big dogs like anatolians,great pyrenese,shepards,, i will just about lay you 5-1 odds thats its dogs espicially if they are killin and leaving it for the most part
