The strongest documented figures I found include a remarkable 22,039-pound pull by two Boerboels in May 2026. However, this figure comes from published competition results and breeder reporting; it is not a universally ratified world record. The International Weight Pull Association (IWPA) maintains its own records, with separate categories for different surfaces.
1. Boerboel
Typical adult weight: 110–200 lb (50–90 kg)
Highest reported pull in this list
- Dogs: Cold River’s Sun Wukong and Cold River’s Mr. Wednesday
- Pulling record: 22,039 lb (9,997 kg) each
- Date: May 9, 2026
- Surface: Rails
- Body weights: Sun Wukong, 164 lb; Mr. Wednesday, 186 lb
Both dogs reportedly moved the same load at the same event. The result is published by their breeder and in a separate review of weight-pull results, but should be described as the heaviest documented result found in the reviewed records rather than an officially ratified worldwide record.
2. Boerboel
CR’s Mr. Wednesday — Boerboel
22,039 lb
- Date: May 9, 2026
- Body weight: 186 lb. (84.4 kg)
- Time: 25.03 seconds
- Surface: Rails
- Breeder/handler: CR Boerboels
Sun WuKong’s litter mate matched the same load. His greater body weight means his load-to-body-weight ratio was lower.
3. Boerboel
Conquest — Boerboel
21,336 lb
- Date: May 9, 2026
- Body weight: 128 lb (58.1 kg)
- Surface: Rails
- Breeder/handler: CR Boerboels
- Class placing: First in the unlimited class, according to the published results
Conquest is particularly impressive because he pulled less total weight than the two dogs above but achieved the best load-to-body-weight ratio among the four top finishers listed in the results.
4. Presa Canario
Hamilton — Presa Canario
19,834 lb
- Date: May 9, 2026
- Body weight: 112 lb (50.8 kg)
- Surface: Rails
- Handler: Travis Torrez
Hamilton’s result is among the highest published pulls for a non-Boerboel in the UPF archive. The same load was recorded for another Presa Canario, Amarillo, weighing 125 lb.
5. American Pit Bull Terrier
JT — American Pit Bull Terrier
18,332 lb
- Date: May 9, 2026
- Body weight: 38 lb (17.2 kg)
- Surface: Rails
- Handler: Emmanuel Faxio
This is a striking result for a small dog. The listed load is about 482 times the dog’s body weight, illustrating why rail-pull results cannot be compared directly with conventional cart or sled pulls
Final thoughts: The extraordinary power of weight-pulling dogs 🐕💪
What an incredible demonstration of canine strength, determination, and athletic ability! These dogs are not simply moving heavy loads — they are showing what years of selective breeding, conditioning, training, and teamwork between dogs and handlers can achieve.
The reported 22,039-pound pull by Sun WuKong and Mr. Wednesday is an astonishing figure. Conquest’s performance is equally fascinating, while Hamilton and JT demonstrate that impressive pulling ability can be found in dogs with very different body sizes and builds.
And perhaps the most exciting part is this: the strongest dog is not necessarily the biggest dog. A relatively small, well-conditioned dog can outperform expectations when its strength, technique, motivation, and training come together.
- Boerboels showcase tremendous power and a formidable working-dog build.
- Presa Canarios demonstrate that other mastiff-type breeds can compete at exceptional levels.
- American Pit Bull Terriers highlight how athleticism and strength relative to body size can be just as fascinating as raw pulling weight.
- Alaskan Malamutes and other traditional working breeds remind us that pulling is deeply rooted in the history of dogs working alongside people.
What makes these achievements truly special is the partnership behind them. Every successful pull represents preparation, patience, trust, and a dog willing to give its best alongside its handler.
One important note: these results are from different pulling categories and should not be treated as a universal ranking of breed strength. The reported loads are competition achievements, not a measure of what every dog of that breed can safely pull.
