There are many possible and invisible underground reasons for the dog collar to activate

I noticed that many causes invisible underground fence dog collar activate an area that should not be. The most common is a stray signal from a cable TV line. This happens when the border fence underground wire or piggy back runs on top of the line of cable TV for a long distance.
There are several ways to know it. The first thing I see is how much the gate signal fields, if it is greater than six meters (ie the dog fence receiver activates the wire six feet underground) and your pet is not test the fence, there is probably room for the signal field is a bit down, and that the stray signal is identified in most cases.
In less serious cases to fix the site will not work. I would try to remove the dog under the fence. If this solves the problem then the problem at the interface between the dog and the fence cable TV. To fix this just a new location for the dog under the fence. The easy thing to do is install a small ground rod outside the garage and attach the ground dog fence bars. You must be a reason for underground invisible fence dog is not a guarantee is invalid.
If the removal of the dog fence transmitter features no solution to the problem and the cable television proberen normal ground outside near the electric meter to remove. If this solves the problem what to do is the cable television should be grounded again where it comes home to block the ground. The ground block is attached to the house where the external underground cable-TV feed line into the house and meets one finds a ground wire that runs the electric meter or shares the same site as the electricity meter bar. You need a cable TV land is what your home from heat or fire. I recommend the cable company to do it or a licensed electrician.
If it does not solve your problem lost signal it is possible that it could be something off a signal similar to your dog invisible fence ondergrondse. It would be a cordless phone or other wireless device type, take a walk around the house with the dog collar fence and keep it up anything you can imagine the problems could cause it to another location . The invisible fence company brand is a wireless transmitter called the invisible mask. That is the problem of stray signals your dog fence problem too. Most underground pet fencing 7k a signal or a signal from the 10K mask has switches for both. If Your Pet Safe, Innotek, or Radio fences are most likely 10k 7k probably any other brand. The mask is designed to operate with no visible mark, but I've seen it work with most other brands. The only one I found this not to work with the dog fence dog watch brands.
