Custom-Shape Havahart® Wireless Extra Collar

Makes Containing Your Dog Safe & Easy

The Custom-Shape Wireless Dog Fence allows you to create a Fence Boundary that contours to your property without digging.

The water-resistant Collar features a Battery Cap design that is flush with the Battery Housing, providing a more secure fit. The Strap is made of heavy-gauge nylon webbing with a 3/4" snap buckle closure. The Collar fits dogs with neck sizes from 14" to 26".

Setup is a Breeze

With the touch of a few buttons, the Collar can easily be paired to your System. Long or Short Probes (both included with your System) can be used, depending upon the thickness of your dog’s coat.

System Safety Features

Havahart® Wireless created a wider Trigger Zone- 6 to 13 ft- to keep your dog safe and away from danger.

The Collar is designed with a Safety Time-Out Feature that stops the correction cycle (a series of static pulses) after 30 seconds. After the correction cycle times out, your dog will not be corrected for returning to the Roaming Area. Once your dog returns to the Roaming Area, the Collar will revert to its normal operating mode and correction will only occur if he again enters the Trigger Zone.

The System will alert you inside your home if your dog has breached the Fence Boundary.
