it depends on how much the dogs weight
there was very soft snow that the dogs had to run through and if the owner ad packed to much weight on to the sled it was harder for the dogs to pull the sled
A typical Pitbull can pull about 2 times its body weight. Despite their strength, they are not built to pull heavy loads like sled dogs.
A group of sled dogs is called a "Team" of sled dogs.
Sled dogs are dogs that pull sleds that have your stuff on them in cold climates.
Two dogs can pull a dog sled, but typical teams can be between 4 and 20 dogs depending how long they are pulling it for and the weight they are carrying.
They tend to live in there sled packs that they pull the sled in
The dogs had to pull the sled
They use them to pull sled through the snow.
They are trained to do it and when being trained learn off the other dogs in the team.
