Scott had used dogs on his first (Discovery) expedition and felt they had failed. On that journey, Scott, Shackleton, and Wilson started with three sledges and 13 dogs. But on that expedition, the men had not properly understood how to travel on snow with the use of dogs. The party had skis but were too inexperienced to make good use of them. As a result, the dogs travelled so fast that the men could not keep up with them. The Discovery expedition had to increase their loads to slow the dogs down. Additionally, the dogs were fed Norwegian dried fish, which did not agree with them and soon they began to deteriorate. The whole team of dogs eventually died (and were eaten), and the men took over hauling the sleds.
