Listing is for PETSAFE IF-100 TRANSMISSION BASE, power cord, metal border flag stakes, box, and instructions. Everything works great. NO COLLARS INCLUDED. We used it with multiple large dogs, and it worked great for them. You can adjust the radius of the dogs roaming area by turning the adjustable switch up or down. It should work great for all sizes of dog as you can also adjust the shock intensity. Will be packaged well and shipped promptly after purchase. Thanks, and happy bidding. Send me an offer on anything in my store and I will negotiate on most items where it's possible.
