7、gural Iditarod Trail Sled Dog Race took place on a route covering more than 1 000 miles in Alaska. There are more competitions in many of the continental United States, and some take place on dry land. In addition to endurance races, sled-dog events include sprint races, weight pulls (in which dogs

8、try to pull the most weight) and freight races (in which dogs try to pull a weighted sled the fastest). Stamina (耐力 ) and Strength Many breeds of dogs are used to pull sleds, including official American Kennel Club breeds such as the Siberian husky, Malamute and Samoyed. However, many sled dogs are

9、of mixed breed and are called Alaska husky or Eskimo dogs. While some Sled dogs may have wolf bloodlines, its generally not desirable to have a mixture of blood between the two. Sled clogs are bred for their speed and endurance as well as leadership qualities. They are big dogs with thick coats and

10、wide, flat feet. They sleep with their tails covering their noses to keep warm. Dogs that weigh around 40 to 45 pounds are the ideal size to pull sleds, but some may weigh as much as 85 pounds. Young dogs that are enthusiastic runners, easy-going and mentally tough are good choices for sled dogs. A

11、dogs gender matters little and both male and female dogs are considered equally. For racing, the most intelligent and fastest dogs are picked to be lead dogs and run in the front of the pack. Behind them run swing dogs, whose job is to direct the team around turns and curves. At the back of the dog

12、team are the wheel dogs or wheelers, who are right in front of the sled and are usually the largest and strongest of the team. The rest of the dogs are known simply as team dogs. Dogs are typically from 2 to 10 years old when they pull sleds. After they retire, they might remain with their owner at

13、a kennel or be adopted as pets by others. Rescue groups for sled dogs take in unwanted dogs and care for them, trying to place them in loving homes.

14、ortation is preferred. Harsh weather conditions can make flying hazardous, and certain terrain can be more difficult for snow machines to cross than for dogs.

15、s of transportation. Becoming a Sled Dog The number of sled dogs at a typical kennel(养狗场 )is around 75, though some might house as few as 20 Or as many as 150. Many kennel owners are greedy mushers (赶狗拉雪橇的人 ) and compete in dog sled races. They also train other mushers and sell and lease dogs. The t

16、raining for each team of racing dogs varies by musher (or whomever is preparing the dogs to race). Conditioning the dogs to run long distances is vital, and teams may cover 2 000 to 3 000 miles in the course of training leading up to an endurance race. Since training may take place year-round, the d

17、ogs sometimes run on dry land, and sometimes pull all-terrain vehicles. Dog owners start training their dogs to pull sleds at a very young age. When they are a couple of months old, they may be fitted with a harness and collar, just so they get used to wearing them. As they get older, a small object

18、 may be attached to the harness to practice pulling weight. Mushers also start teaching the dogs verbal commands. When dogs are ready to train alongside a team, at around 6 to 8 months old, they start by pulling light loads for short distances. Over time, they build up their strength and stamina and

19、 are able to go farther and pull more. Sled dogs that are well cared for and loved by their owners are quite friendly and gentle. While they may fight with other dogs, it is rare that a sled dog would be aggressive toward people. Mushers have been quoted as saying that they take better care of their

20、 dogs than themselves, and that the dogs eat better than they do. Relationships between dog and musher vary, but most mushers consider their dogs family. Mushers generally follow the reasoning that a dog thats not properly cared for will not perform, so it wouldnt make sense to mistreat dogs. For ra

21、ces such as the Iditarod, veterinarians are on hand to examine dogs, and race rules require proof of certain vaccines and check-ups. Dogs are implanted with microchips to help keep track of them. The International Sled Dog Veterinary Medical Association is a group of veterinarians who are dedicated

22、to the welfare of sled dogs. Getting Ready for the Race Racing sled dogs need to eat around 10 000 calories per day. During the Iditarod race, that translates to about 2 000 pounds of food for one team for the entire race. Meat is the main ingredient, but they also consume other fats, oils, dry dog

23、foods and vitamin supplements. Dogs eat at each of the more than two dozen checkpoints on the Iditarod route, but they also get snacks every few hours. Gear for dogs includes fabric booties to protect their feet from the elements, and a sled team may go through 2 000 booties during a race. The numbe

24、r of dogs pulling the sled varies by race and by musher. In the Iditarod, there are a maximum of 16 dogs on a team. At the races start, there must be between 12 and 16 doge per entrant. At the races end, at least six dogs must be part of the team that crosses the finish line. The dogs are attached t

25、o the sled with a series of lines called rigging. This includes the tow line (or gang line), tug lines and neck lines. Each dog wears a collar and a harness. The tow line connects the dogs to the sled, and a tug line rigs the dogs harnesses to the tow line. The dogs collars are attached to the tow l

26、ine by the neck line. There are no reins, and dogs respond to the mushers vocal commands. A musher says “hike,“ “lets go,“ or “all right,“ to get his or her team going; “easy“ to slow down; “gee“ to turn right; “haw“ to turn left; “come gee“ or “come haw“ to turn 180 degrees right or left; “straight

27、 on“ to go straight ahead; and “whoa“ to stop. During the Iditarod, teams typically travel in the 5 to 12 miles per hour range and might run for six or eight hours straight. When dogs fail to work together as a team, or a musher cant properly direct his or her team, the lines can become tangled and
