I understand yalls concern and appreciate it. I thought about an electric fence and still am but I have two boys 5 and 3 years old and would hate for them to get zapped. Then I said "Well I can just turn it off when me and the boys go out". Now the neigbor kids shouldnt be near my pature or horse so if they get zapped opps. (I know that's mean! Lol) I know theres a first for everything but I have never had an incident with barb wire and where the horse is coming from they use barb wire. I actually priced and looked at electric as well. My first choice would actually be that flexible square wire fencing that you use for goats and stuff (I can't recall the name). It would be safe and keep out dogs and people. If any thing works out I have already looked into metal "No Tresspassing This Property Is Leased For Private Use" signs to hand on the fence.
Honestly, if neighbor kids are trespassing and they get zapped, they'll learn pretty quickly to keep a safe distance
. You could definitely turn it off when your kids are out, even though you should still try to teach them to keep a safe distance from the fence. Most horses that are used to electric fencing won't test it, even if it's turned off for a few hours.
