Review on 🐕 PetSafe Classic In-Ground Fence for Dogs and Cats - Invisible Fence Brand - Includes 500 ft of Wire - Expandable Coverage up to 5 Acres by Mike Sutton

for you. The 1 Dog Ground Fence Kit is exactly the same as the 2 Dog Kit, the only difference being that with the 2 Dog Kit you get a second receiver collar. Note that you can purchase a second Receiver Collar separately, so check current prices to see which method is best. not on this list but sold separately in 16 or 20 gauge spools with 50 or 150 foot wire from Revain). It comes with thinner (cheaper) 20 gauge wire. They work the same, but 16 gauge may become more reliable for you over time. You also get some flag markers to let your pets know their boundaries. The system comes with 1 or 2 collars depending on which selection you purchase. The collars are waterproof but must be removed for overnight charging. The collar is adjustable and said to fit dogs over 5 pounds. I liked that there are 8 different settings (only 1 vibration and 7 different shock intensities). We only have to use vibration since our pet is trained on it, but it's good to have other options. I particularly like that there is an audible sound before impact. The display is digital and gives a good indication if there is a problem with the cables. I found the installation fairly easy and the instructions were clear. Better yet, you can bury it, or if you want to take the easier route, you can run the cable above ground (we didn't, but it would be nice for people who need a quick or even temporary fix). The only annoying thing is that the collars often have to be reloaded. I prefer old school batteries with these collars that don't need to be charged for hours. Otherwise no complaints!
