November 21, 2025
Bully Max Sports today announced the results of the second Unified Pulling Federation (UPF) sanctioned weight pull event held at the Bully Max Training Facility. The event continued Bully Max’s role as a host site for elite competitive dogs participating under officially recognized UPF standards.
The competition featured Sun Wukong, an African Boerboel owned by Eli Carver of Cold River Boerboels (coldriverboerboels.com). During the event Sun Wukong completed an officially judged pull of 16,917 lbs, setting a new UPF-recognized world record.
UPF judges were present on site to verify all results in accordance with federation rules. The record pull and full competition proceedings were documented following official UPF procedures.

How Dog Weight Pull World Records Work
A weight pull record only means something under a specific federation’s rules, because each organization sets its own surface, cart, distance and classes. Under the UPF weight pull rules:
- Distance and time: a completed pull covers 16 feet from start to finish line within 60 seconds.
- Surface: pulls are run on a rail system or on wheels over dirt or carpet.
- Classes: dogs are weighed in no more than 24 hours before the show and placed into weight classes across four divisions.
- Awards: the most weight pulled wins each class, with division awards for Most Weight Pulled (MWP) and Most Weight Pulled per Pound (MWPP) of body weight.
- Dog welfare: dogs must be at least 36 weeks old, wear their own freight harness, and may not be baited during the pull. Performance-enhancing drugs are banned, and human- or dog-aggressive dogs are not allowed to pull.
That is why records from different organizations, or from snow and sled pulls, can’t be compared directly. A rail or wheeled cart rolls very differently from a sled on snow.

Which Breeds Set Weight Pull Records?
Big records in the heavy classes tend to come from large, powerful breeds like Boerboels and other mastiff types. Per-pound awards are where mid-size bully breeds often shine: American Pit Bull Terriers, American Bullies and Staffordshire-type dogs combine muscle, drive and a strong work ethic. Read about two pit bulls that pulled 11,806 pounds, and see how the bully breeds compare.
Thinking About Weight Pull With Your Own Dog?
Record pulls are the end of years of conditioning, not the starting point. If you want to try the sport:
- Get a vet check first. Your dog should be fully grown and physically sound. Puppies should not pull weight.
- Use a properly fitted freight harness, never a collar.
- Start with an empty or very light cart and lots of praise, then add weight slowly with an experienced trainer.
- Build general fitness with walks, sprints and play, not only pulling.
- Feed for the work. A pulling dog needs enough calories and protein to hold muscle and condition.

Dog Weight Pull Record FAQ
What is the world record for most weight pulled by a dog?
The UPF world record announced in November 2025 is 16,917 lbs, pulled by Sun Wukong, an African Boerboel, at the Bully Max Training Facility. Other federations keep their own records under different rules, so their numbers are not directly comparable.
How much weight can a dog pull?
It depends on the dog’s size, conditioning, the surface and the cart. That is why UPF also awards Most Weight Pulled per Pound, which compares pulls relative to body weight.
Is weight pulling safe for dogs?
For a healthy, adult, well-conditioned dog in a fitted freight harness, with weight added gradually, it is a sanctioned sport with welfare rules. It is not for puppies or dogs with joint problems. Ask your vet before you start.
