A wireless dog perimeter fence usually includes a transmitter, perimeter dog collar and visual cues. The transmitter uses radio frequencies to help create an adjustable invisible perimeter, your dog wears a collar that detects the field, and when your pet crosses the boundary, the collar emits a correction. This correction, which can be tonal or static, has been compared to a splash of cold water. It is designed not to harm your dog, only to surprise them enough to disincentivize the incorrect behavior. The correction can also be adjusted to match the sensitivity level of your dog.
The visual cues are typically small flags placed along the barrier’s front edge to help your dog understand the boundary. Over time, your dog should naturally get a sense of the border, and the visual cues may no longer be necessary.
Petco also offers electronic dog training collars & accessories for you to add to your wireless pet fence system.
