The listing, INVISIBLE FENCE has ended.
I bought this after having to bail my 3dogs out of doggie jail several times . It's brand new I put the collar on one of my dogs to make sure it was going to be strong enough to stop them (they are pitties) IT WAS!! Due to the type of dogs we have we ended up just installing a wooden fence all the way around our property, so it's just been sitting on a shelf for a year! It has several power levels to match up the "shock" with the type of dog you have it will give the dog a warning beep or buzzing noise first before it shocks them, if they continue to cross then it will send the shock . It also has a setting where it will only make the sound if the animal tries to go out of bounds (works just as good as the shock) It has over 900 feet of boundary wiring and also has a alarm that goes off if the wiring breaks anywhere or if ur puppy gets past the parameters
