Hey guys, I keep six running walker and July's behind an underground containment fence. The key factor is, you got to be smarter than the dogs. The only time mine ever get out is if I forget to charge their collar or the electricity goes off. The system has a reminder, but I don't turn it on. You can also put batteries on the system, which I don't do. If I lived in town I would be more serious about the system. My system works so good that all my neighbors now have their dogs behind the wire. I must say there is a trick to keeping the hounds behind a simple wire, but it can be done. I have a five acre wooded lot fenced in. I love to watch my dogs play chase. I run coyotes in pens, so when my dogs get bored one dog will be "it" and all the other dogs will chase him until he goes into his safe place, and the game is over. lol
Now, the first person who can tell me what the trick is wins a brand new fur-lined pee-pot. If you will think about it long enough you will figure it out. (How do you keep a stupid hound dog behind an underground wire when coyotes and deer walk through the yard almost every night?) Oh! and one or two stray dogs have been dumb enough to cross the wire. The U.P.S. man can't figure out why them dogs bark so viciously and all of them stand in a line next to one another but never come over to where he is? I have the wire run so the dogs can't get up near the house or parking area. Ya'll let me know the trick now. I forgot my dogs never have sores under their necks either. You can work on that solution to.
