Super easy to install. Took a few runs for our dogs to understand they couldn’t dig under the fence. They know to stop when they hear the warning sound from the collar. Haven’t had a loose dog, our pack of four mastiffs and one Aussie shep/lab, since we installed this system, +/- six months. One mastiff jumped through it twice when the gate was open; doesn’t dare to get near the fence If the gate is closed. Highly recommend if you have a fence already. Not sure it would be dog proof without something to physically keep them in the yard.
