I understand the concern for your dogs. We had to stop shooting doves behind my partner's house because of his wife's dogs and the neighbor's kennel 300 yds away.
Your neighbor is really out in front of a "free-for-all"
season. The legal limit for doves varies but 10-12 per day and the limit with 20-24 in possession. Your neighbor is a
"game hunter slob".
I wondered what was the limit. He 'baits' his field too...is that legal?
