I watched it just this morning. Two deer left the woods and started across the pasture next to me. Immediately, my neighbor's 2 dogs started barking and began a pursuit. Two more deer showed up on a trail that would've led them past me, but they were watching the dogs chase the other deer. When the dogs came back, the deer near me thought they were next and went back quickly the way they came. Those two dogs search my side woods every morning and chase every deer they can. It's a game for them. I've talked to the owners about it, but it continues. I won't shoot them, but I can only take so much.
