How do you find breaks in an electric dog fence?

Question

Isn't there some way that you can use an AM radio?

Answer 1

This is done in the same way you find breaks in any wire.  

Check out the wire itself. If it entails digging it up or removing it from a wall, this may be required.  Use resistance measurements to isolate segments and go from there.

There is no easy way.

Answer 2

drag your dog around by its leash,

no just kidding, call an electrician, there is a tool that can check it for you

Answer 3

Put on the collar and walk around.  I don't see any other way...

Answer 4

I dont think an AM will respond to the frequence but you are correct if your using one of the wireless type fences. I believe you will need an electric fence voltage indicator (usually in the 10,000 volt range) and attach it to the electrodes on the collar this way you can see it lite up when you cross the good part and it wont lite where its bad.  You can buy aligator clips at Radio Shack (and maybe a tester too) to make the connections to the collars electrodes easier and more secure.

Also before you start change all the batteries and check the battery connections.

Answer 5

Is this an underground fence? If above ground even a blade of grass will cause problems.
