Don't know who's running Colo Springs IFC, I started Invisible Fence Co back in the mid 1984 in Colorado, Arizona, New Mexico, based out of Parker and Denver put over 5,000 dogs on the system, It works great if you fence can appropriate amount of boundary 1/4 acre or more, spend at least 3 days boundary training , most important is making sure the collar is up high ,prongs are touching the curvature of the neck,
the biggest problem ,collar to loose, Some breeds of dogs are PIA , and need special attention, spade and neuter your dogs.
If the people PM me I'd be happy to chat, if they luv dogs enough to spend that much money, it should work, hope IFC kept the fundamentals basic boundary training with audible command and stiff correction.
