PetSafe Stay & Play Wireless Pet Fence with Replaceable Battery Collar – for Dogs & Cats Over 5 lb – Waterproof Receiver Collar Tone & Static Correction – from Parent Company of Invisible Fence Brand

An excellent boundary tool!
This wireless fence system is very easy to install and works very well for our high energy dog. Our property is not fenced, but is essentially flat so we were able to achieve a consistent boundary perimeter. We bought a package of 100 yellow plastic flags and are using them rather than the 50 flags included with the system, as we needed that to achieve an even ten feet between flags. We followed the training instructions exactly as described, and by the second day, our dog would not go so far as to be within the buzzing-alert range. The first 4 days of training, I kept him on the leash and walked in all directions towards the boundary, multiple times each day. He consistently initiated “putting on the brakes” as we approached the boundary, so I would lavishly praise and reward him. Days 5 – 8, I still kept him on the leash and added distractions. He completely restrained himself and would not pursue the toys or people approaching until they were far enough within the boundary for the dog’s comfort. Days 9 – 30 (we’re currently on day 24), we moved to unleashed supervision and play. We’ve successfully played fetch an unlimited number of times every day and played endlessly with the kids. If the ball happened to land too close to the flags, he would not go get it. Or, if the kids left the boundary, he would not follow them through it. However, one afternoon around day 17, a cat was meandering within the boundary and the dog saw it from inside and went nuts. When I let him out the door, he chased the cat through the boundary. He got alerted and zapped but didn’t stop until he was a hundred yards away. Then he came to a complete stop and walked back to me. We walked inside the boundary and I praised him for coming back within safety. Following that, I walked the boundary with him on leash again and he would not go anywhere near the edges. After that we went back to unleashed play and supervision, and he has not chased anything through the boundary again. Two days ago, as we went outside, we surprised the cat, who ran away quickly. My dog gave chase for about 6 feet, then stopped well within the boundary and just turned around and looked at me. I praised him lavishly again. I’m very optimistic that this will be a reliable, long term solution. I recommend it.

Still pleased but need to update my review.
UPDATE: Although I am still pleased with the overall concept of this product, I am becoming increasingmy frustrated with the power cord. FOR this to be not the best location possible for my dogs I needed to have it plugged into an extension cord. FOR whatever reason, and after trying multiple cords, the unit continuously and randomly loses power. If this happens while I’m at work and the “no power alert” is no longer sounding, the unit is useless. I will be reaching out to Amazon & Pet Safe for a response.Love, love, love this! Just what I was looking for. We have a large yard that would be difficult to fence in but needed a way to contain two newly adopted yellow labs. It took a bit to figure out just where to place the base to keep them away from the neighbors yard on one side but give them enough space to join us at the pool on the other. I would give this five stars if the base could be located outside. I currently have it in the garage as that’s the location that gives the best radius. I was slightly concerned with the volume of the tone being so low, I’ve only ever needed to use tone – they respond very well! After using this for approximately six weeks I’m thinking the volume is fine, I’d still be happier with a louder tone though. I’d also like to see more choices in collar color. My labs look almost identical and when out in the yard it’s tough to call them by their correct names without having those helpful hints! A choice of black or red just doesn’t do it for me!The training materials were helpful but honestly, it only took me three days to show them their boundaries before I was comfortable with letting them out off leash. They respond very well and learned quickly. I’m still paying close attention as we do have “wildlife” all around but they’re doing excellent – the didn’t chase the squirrel that ran across the driveway out of their boundary so it’s all good!All in all, very pleased with this unit and would recommend it.

We have 4 dogs and also foster dogs of all ages and this system was so easy to set up! We have tried wire fences, regular fences etc. and nothing has worked comparable to this! Our dogs were trained to the fence within a couple days and the set up took less than an hour.

Product worked wonders.. for the small amount of time it actually worked. I bought a 2nd collar (rechargeable) and it’s been a pleasure to teach my dogs their perimeter without being hard on them. After a few weeks at most, they knew their limits and never crossed it without us, even without the collar on.But now, after 3 months of use, it’s started shocking my adult dog randomly, while he was still in the house (so nowhere near the limit of the perimeter). My dog is shacking right now, won’t go outside as he’s scared of getting shock again.I tried resetting the Emitter, changing the batteries in the collar, nothing works, it still randomly shock (while I hold it, no way I’m putting that on my dog again).Very disappointed by the short lifespan, but especially by the “bug” that did hurt my dog. I can’t recommend it at all. Seems to be the PetSafe station that is problematic…

This over all is a good product. The only thing I wish I had known is that you need to replace batteries. My dog learned in less then a day the boundary’s
