I bought the guardian GPS fence for my two Colorado Mountain Dogs (Great Pyrenees and Anatolian Shepherd mix). My property borders National Forest, which is filled with every kind of wildlife you can imagine; deer, elk, badgers, bear, bobcats, fox, coyotes, jackrabbits and more. Recently, in it's infinite wisdom, (not) the state of Colorado has released wolves into rural areas of the state and on Easter Sunday I watched one wander right behind my house. Luckily I was right there and able to stop my dogs from going under the fence after it. But I realized at that point I had to do something serious to keep them from going under my fence so I splurged a good chunk of money and prayed these two collars would work. It only took me about two hours to set everything up and then just a couple of days training a little bit at a time so that my two dogs understood what the beep meant at the fence line. The true test came just two days ago when two coyotes decided to romp right past my fence line. In the past, my older dog would've been under the fence and after them. This time she stood back 10 feet from the fence, barking her head off and so did the puppy. I can't tell you how relieved I was to know that with a test like that they still respected my fence. I recommend the guardian GPS fence, but you have to be willing to take the time to train your dogs. If I'd had a bigger budget, I would have bought the guardian GPS fence with tracking, but I am widowed and retired and the monthly subscription cost put it out of my price range.
