Welcome to Trimworks dog guard & fencing

What is dog guard?

DOG GUARD is an underground electronic fence system that is installed by burying a single wire as a complete loop along the entire perimeter of your property. This underground boundary can also include certain portion of your yard, such as a pool or garden. Your dog is safely contained within your yard, while not being allowed to trample your gardens or swim in your pool.

Out of Sight Fencing

Dog Guard Out-of-Sight Fencing is a safe, affordable alternative to traditional fencing, which uses a veterinarian-approved combination of animal training and state-of-the art electronics that allows your dog the freedom he deserves and provides you with peace of mind. Underground pet fencing is safe for your dog or most pets.

Because each installation is customized, you define the boundaries. We’ll work with you to protect your pet from driveways, pools, and other dangerous areas. Our system can also protect your flowerbeds, shrubs or other areas from your playful pet.

Dog Guard uses a combination of warning signals and stimuli to keep your pet in the safety of your own yard at all times and out of harms way.


Capable of covering up to 50 acres, these units have three user-friendly indicator lights to let you know that the system is working properly and an audible alert to let you know if the system malfunctions.


The receiver is designed to provide up to 32 levels of adjustable stimulation and can be ordered with or without a one-second delay. The delay provides a warning tone before correction occurs.

Room Transmitter

The Room Transmitter is a small wall mounted device that is designed for containing or restraining pets in designated areas of the home.
