It's part of the annual dog pull contest.
The furry participants are fitted with special harnesses which allow them to pull an increasing amount of weight safely.
Contest organizer Phil Goerner says how much weight they pull is strictly up to the dog.
"Any breed of dog will pull," Goerner said. "Most dogs are natural pullers and with a little training, will astound you, but if the weight gets too heavy for the dog, it simply will not pull," he added.
Tonight's winners were:
In the 20-pound class, a Patterdale terrier by the name of Shorty pulled 585 pounds
In the 40-pound weight class, a Pitbull by the name of Serena pulled 1100 pounds
In the 100-pound class, Teka, an American bull dog, managed to pull 2800 pounds
And in the 125-class, Bridger, the lightweight of the group at 105 pounds pulled a whopping 3400 pounds for the win
Organizers say the dogs are not hurt when participating in the contest.
