I would think that even with a field point, it would be good to dull it down for the safety of the dog. Years back, guys were using bludgeons. A solid could bring pheasants down hard, but anything less they were not so predictable. If your bow has enough power, a steel blunt will work, but nothing is as good as free three blade broadheads. My last one was with a wore down Hill. The pheasant went down and died quickly, but the arrow is hiding somewhere in a brushy Iowa creek bottom, a case of too much penetration, hopefully point down and in the dirt.
