Invisable fence users?

does anyone else have an invisable fence here?

I'd be interested to know if an invisible fence works ... I've heard of dogs that were able to get past them, though.  I imagine that it wouldn't last long with a clever dog ...

My sister has a large yard in the country and has an invisible fence.  Her dog was very easily trained... never crosses the boundaries -with or without the collar.  Interestingly, Molly (dog) doesn't cross the boundaries in non-fenced yards either.

all my dogs are fenced trained (except for rosey... the angel!) and even without there collars (now) they stay in the yard. Dogs are creatures of habit do once you have fully trained them, it won't matter. I always keep there collars on though because i wouldn't want to risk losing anyone(even though i'm outside with them 99% of the time usually)! i think it is a great idea! there really cheap compared to a regular fence (big time) and they are a great prevention of lost dogs.

So you two have had successful results?  I'm glad it works, because my cousin considered an invisible fence.  I convinced her otherwise, though.  Maybe I should mention a few success stories.  A typical fence does cost an arm and a leg, which is why she wanted the invisible fence.  Last I heard, she hadn't gotten either fencing system.  

Dont they get zapped if they walk through it???? What exactly keeps them from getting through?

From what I understand there is a "hum" or something to warn the dog that he/she is getting too close to the boundary.  And yes if the dog proceeds, he/she gets shocked.  My sister was not really keen on that aspect of the fencing, however; she felt she needed something to ensure her pet's safety...and a typical fence wouldn't have been possible given the nature of her yard. Thankfully Molly learned her boundaries on day one...and like I posted earlier, she seems to have generalized the "boundary" idea to other yards as well.

I tried one since Tonkas breeder uses one, it didnt work, he would stand on the line and get zapped, he didnt care.  Once a dog learns that they can get trough and be fine on the other side they dont forget.  I would suggest the proper one that you get installed rather than the home job kit they do work away better from what I have been told.
 
My only honest concern with them is the fact that it doesnt keep other dogs out.

we have one. It works very well. If you put the time and effort into training most dogs will stay in even if you forget to put their collars on. It's the training that keeps them in. The fence is just a "training aid".

We just bought a PetSafe invisible fence for our dog.  We are only in the first week of training her to it but it seems to be working.  She got shocked once and now she'll back up when she hears the beeping.  We are still on-leash at this point but I'll let you know how it goes moving forward.  
 
My parents installed one for my grandmother's stubborn little terrier and it worked great.  My dad trained her and they never had a problem.
 
 

when the dog strats getting towards the boundry it starts getting a tone. the tone gets more frequency as it gets closer and closer. eventually they get to close and will get a shock. you can either get a collar that you can control the tone and shock or just get a fencing. they make a connection with the tone and no that with it comes the shock!
now all we have to do is give them a little tone and they know!

My aunt's dog learned to run through it.  I guess I just have a *thing* against invisible fences.  I don't like walking/horseback riding down a street and having to guess at whether the dog charging at me is behind an invisible fence or not.  There used to be a pair of yellow labs whose yard butted right up against our horse trail.  They would fly down the hill barking and carrying on--most of the time it was just noise.  One of them would come when called, but the other *really* wanted at the horses.  I would occasionally hear a beeping (I'm guessing that's the warning tone), and one time the dog did get zapped.

I've had a similar experience to Christina with a dog in an invisible fence. My dad and I took Max on a walk to get water ice, and as we passed by a house,a dog came flying at us. It looked like it wanted to tear into Max. Max of course wanted to play with it, so I had to drag him past it. It must have hit the end of it's area and gotten shocked, because it all of a sudden ran off, or so I thought. As we came up to the front yard of the house, the crazy dog came flying at us again.
There are also two black labs in one at a house near one I work at. The first few times I came down the street, the dogs came tearing towards the road. I thought they were going to run into the street and I was going to hit them. I found out there was an electric fence on the yard when they got to the edge and turned back. Now that they've seen my car enough times, they don't run at it, but those first few times were nerve wracking.

In my experience an invisible fence is an appropriate tool in the right situation.  It's not right right for ALL dogs, ALL yards, and ALL neighborhoods. 
 
BUT for the ones it is right for...it can be a life saver.
