Ultra-Smart In-Ground Pet Fencing by Innotek

Innotek says:

This popular in-ground fencing system features the UltraSmart rechargeable collar, the thinnest, sleekest, most stylish collar available. It is contoured for comfort, sleek and waterproof. The collar is paired with a transmitter that powers a boundary up to 25 acres.

How It Works

A radio signal travels from the Fence Transmitter through a buried wire, marking the boundaries you wish to set for your dog. Your dog wears a Receiver Collar that detects the signal at the boundary. As your dog approaches the boundary, the receiver issues a warning tone. If he proceeds further, he receives a safe but startling Static Correction. While harmless, the correction will persuade him to stay in the containment area you've established. Boundary flags are a temporary visual aid for your pet; remove them after training.

This Innotek system has been proven safe, comfortable, and effective for pets over 5 pounds.
