he first step in underground dog fence training is to introduce your dog

The first step in underground dog fence training is to introduce your dog to the boundary. Walking the dog along the fence line while holding the receiver collar will help familiarize them with the area they should avoid. It's helpful to use visual markers, such as flags, at the boundary line during the initial stages, giving the dog a clear visual cue of where the boundary is. This step ensures that the dog has a visual understanding of the limits of their play area before any correction is introduced.
