Optimizing the performance of your vehicle starts with understanding what it is doing and how it is performing. As you modify your vehicle in any way it is important to know and understand what those modifications are doing to your vehicles performance, it is also important to understand these things when altering your chassis set-up and/or your driving style.

Keeping an eye on vehicle parameters such as temperatures and speeds is also very important to any performance vehicle owner. The Bully Dog WatchDogTM provides users with all of these features in one unit. The monitoring features of the WatchDogTM can be customized in many ways including: gauge layout, colors, parameters monitored (allows 4 parameters to be monitored at one time on the high capacity, crystal clear screen), warning/alarms and settings. Everyone has dreamed of having a race track of their very own to test their vehicles performance, the WatchDogTM almost fulfills those dreams.

Enter some basic information for your vehicle such as engine size and away you go. Measuring acceleration/deceleration time and distance, lap times and more through advanced data collection gathered; that information is then processed by the Performance Management software in the WatchDogTM. The end result is information that is accurate within a .10 of a second. Simple installation on any* vehicle made since 1996 allows users to get right to business monitoring what your favorite performance vehicle is doing and how it is performing.

More Info


It is proven that drivers who change their driving habits to maximize fuel economy can see improvements up to 37% per gallon of fuel. Recognizing this fact, Bully Dog designed the first software of its kind into the Watchdog, thus being first to market again! 

The information is gathered from the sensors that each vehicle is equipped with from the factory. Information is gathered during operation in real time, the software then process the information. As the information is processed, it is then used to serve as a Driving Coach guiding the vehicle's driver to the most efficient, economical driving techniques in order to maximize fuel economy. 

The Watchdog becomes a very valuable tool as a Driving Coach. A priority in today's market place is saving fuel, getting every last tenth of a mile out of the fuel in the tank. The Watchdog features software that tracks the driver's habits behind the wheel. As these habits show themselves, the software calculates the best remedy and then notifies the driver. As a Driving Coach the Watchdog will recommend and suggest different driving methods to the user in real time as conditions and habits become apparent. 

For instance, If the driver of the vehicle is repeatedly waiting until the last minute before applying the brakes before coming to a stop, the software will recognize this and then advise the driver how they can improve their braking method and their fuel mileage. 


The WatchDog Gauge offers a comprehensive digital gauge package including all standard PID or vehicle parameters included in vehicles '96 and newer. The gauge will display a combination of any four parameters with over 20 different ones to choose from depending on your vehicle. These gauges are all displayed at the same time on an easy to read digital display. The following is a list of parameters that the WatchDog is able to read from your vehicle. These parameters rely on sensors that your vehicle was equipped with from the factory, not all vehicles have all of these options available.

About Bully Dog


Bully Dog was formed in 1998 in Aberdeen, Idaho. The founders of Bully Dog – Michael, Phillip, and Daryl Klassen --were heavily influenced by their father Harold's interest in improving vehicle performance. Several years prior to the company's inception, Harold had experimented with increasing performance on his diesel farm tractor by injecting propane into the engine's combustion chamber. In 1998, Bully Dog's owners took this concept and developed and patented a safe and effective propane injection system to enhance diesel engine performance. These systems were first sold out of their farm shop, but as demand increased, the owners moved the company to another location and officially organized Bully Dog. Bully Dog's quest was now to be recognized as the leader in the diesel performance industry, which motivated us to stay abreast of new technology in this industry. With the introduction of electronic components and software to improve performance, we began to research new types of products like intake and exhaust systems to complement our electronic components. Bully Dog was now able to offer a complete performance package. In 2005, the company expanded its range of products to include performance products for gasoline powered vehicles. 

The Products

Bully Dog products are developed with you in mind and each of you has a different need, want and desire. Our products, all the way back to the first propane kits, reflect that. Bully Dog products are built to be flexible, allowing each user to get their own desired result, from outrageous performance on the race track to improved fuel economy driving down the highway. Bully Dog products have you covered with increased performance, added safety and improved economy. This is evident with the Triple Dog™ GT line of product for gas and diesel vehicles, the Performance Management Tool and our new line of big rig and industrial products. 

Product Development

Each Bully Dog product is built to ensure that it consistently meets and exceeds expectations, yours and ours. Each product goes through an in-depth research and development process (R&D) followed by a grueling development procedure that is carried out by a staff of the best engineers in the world. Once designed, each product is put through months of real world testing. This testing is performed across the United States so that Bully Dog can be sure that each product works correctly and flawlessly in various elevations, weather conditions and driving situations from towing a heavy load to racing down the track. 


Product innovation is key and Bully Dog takes innovation very seriously. In the past 12 years, Bully Dog has been first to market with vehicle-specific products and applications over 100 times while also being awarded many awards for our revolutionary products. And in 2005, with the release of the Triple Dog™ Downloader and Outlook™ Monitor, Bully Dog revolutionized the market with the ability to adjust power, safety and economy levels on-the-fly while driving down the road. Then in 2008 with the Triple Dog™ Gauge Tuner, we were able to combine a vehicle engine tuner, monitor, gauge and diagnostic device all in a single unit. The GT monitors and displays over fifteen different vehicle parameters (PIDs) and it includes our all new Driving Coach feature which teaches end users to maximize their vehicles fuel economy potential. The GT performs vehicle diagnostics by reading and erasing diagnostic trouble codes; this level of vehicle transparency isn't offered by any OEM or by any ot her aftermarket product. Also included is our performance testing feature designed to test a vehicles' performance capability on the drag strip; couple this with our free PC analysis software and users can also determine vehicle horsepower. The GT does it all and it works on the largest range of gasoline powered vehicles; in fact the GT works on eight different vehicle makes and over 50 different models. The WatchDog™ was introduced in 2009 and works on all 1996 and later vehicles with an OBDII port common to North America. The WatchDog™ serves as a digital gauge/monitor and features a valuable Driving Coach for gas and diesel powered vehicles. It features the ability to monitor over 20 vehicle parameters all while you receive valuable driving suggestions from the Driving Coach to maximize fuel economy.
