This same owner and I had a direct discussion; that discussion followed a visit on another occasion when the Alachua County Sherriff deputy explained, and had them read, the appropriate portion of the FL legal code, that a dog attacking livestock can be destroyed by the livestock owner. Said owner stated he didn't want any trouble. I explained to him that I don't either, and for me trouble starts when someone lets their dogs loose after my livestock, since they represent dollars, not pets. So some dog killing livestock is the same as stealing from me.
Fine. We live in the country now. Dog may not come home one day. Things like that happen, too.
