What are the limits of sled dogs? What to Know

Why is There a Weight Limit

In general, the more weight in the sled, the more dogs required to pull that weight. We do not have an unlimited number of dogs. We keep enough dogs to handle fifteen, near weight limit sleds on good trail conditions.

Driving a dog sled takes skill. The more weight that is in the sled, the more power is required to keep the sled moving, and the more skill that is required from the guide to control that power. We are comfortable with the amount of power and skill required to pull 350 pounds of guests.

Sleds (on snow in winter): 8 months Carts (on dry ground, not winter): No limits really The ride is a sedentary activity that people of all ages can enjoy. The ride is also completely outside and the guests will experience the weather as it happens and the trail conditions as they exist. In most circumstances, the ride is suitable for people between the ages of one and eighty. In perfect conditions the ride is suitable for people between six months and one hundred. In poor conditions the ride is barely suitable for our professional guides and dogs.

Our rides are fairly gently and accessible to most people most of the time. If you have any of the following conditions, however, you may want to reconsider our rides or consult a doctor (who will say dont go on the ride) or a trusted confidant.

  • Pregnancy
  • Recent, invasive surgery
  • Recently broken bones
  • Dog allergy
  • Small bladder
  • Motion sickness
  • Hangover
  • Back or buttock pain
  • WEIGHT AND HEIGHT LIMITS SUBJECT TO CHANGE BASED ON TRAIL CONDITIONS.

    Due to the unguided nature of hangouts and the number of loose dogs around you, hangouts are limited to ages ten plus.

    How many people can dog sled?

    How many people can mush at once? When we’re using the sleds, up to three people can be in a sled/wheeled vehicle at one time.

    Sick, injured, tired Iditarod dogs don’t want to run

    Craig Medred, outdoors columnist for the Anchorage Daily News, told Weekly Reader Current Events (3/3/06), “It’s pretty hard to imagine the enthusiasm these dogs have for racing….”

    But dogs feel pain just like humans do. They are not machines.

    How can dogs be enthusiastic about running when they’re sick, injured or exhausted?

    Do you think these dog are enthusiastic about running in the Iditarod?

    “Brutal winds and temperatures to 20 degrees below zero were terrorizing those who hadn’t yet made it through Rainy Pass.”

    “Wind chill temperatures were pushing down to 55 to 60 degrees below zero.”

    “Conditions were so grim dog teams hoping to continue down the Iditarod Trail were having a hard time just getting out of this checkpoint Monday night and early this morning. They struggled in the dark, wind and cold.”

    – Craig Medred, Anchorage Daily News, March 6, 2007 [

    “‘(The winds) literally picked your whole team up and threw them off the trail.”

    81 percent of the dogs who finish the Iditarod have lung damage:

    “To investigate, the team of researchers examined the airways of 59 sled dogs 24 to 48 hours after they completed the long and arduous race. Their findings are published in the September issue of the American Journal of Respiratory and Critical Care Medicine.

    The researchers found that 81% of the canines had “abnormal accumulations” of mucus or cellular debris in their lower airways. This accumulation was classified as moderate to severe in nearly half of the animals, according to the report. There was no evidence that the lung damage could be due to bacterial infection, the authors note. Instead, they say, it was likely caused by cooling and drying out of peripheral airway passages, resulting in injury and inflammation.”

    – Reuters Health,Tue Oct 8, 2002, 2:17 PM ET

    Airway dysfunction persists despite 4 months of rest:

    “CONCLUSIONS: Racing Alaskan sled dogs have airway dysfunction similar to ‘ski asthma’ that persists despite having 4 months of rest. These findings suggest that repeated exercise in cold conditions can lead to airway disease that does not readily resolve with cessation of exercise.”

    Race officials encouraged injured musher to continue racing tired and sick dogs:

    “Coming into the Ruby checkpoint, 615 miles from Anchorage and just under 500 from Nome, Madsen had just come through a hard run along the Yukon. He and his team had endured miles of fighting 50 mph sustained winds with gust up to 75 mph. There were places the trail was blown out.

    Madsen was burned out, and the dogs were not rested. He knew they were going slowly.

    Some of the dogs had been sick with diarrhea and treated at a prior checkpoint. They showed little spark after that.

    Battling the winds, Madsen could practically see their body fat melting off. Not only that, the sled hit a stump on the trail forcing Madsen’s upper body into the handles. An X-ray at a later checkpoint revealed a rib broken in several places.”

    “After two or three hours of sleep, some food and a pep talk from race officials, he felt he could go on.” [Emphasis added]

    Kennel cough is highly contagious:

    “Kennel cough can be caused by a combination of viruses and bacteria. It is very contagious and your dog can become infected if it comes into contact with an infected dog.”

    – American Veterinary Medical Association, website article, March 18, 2011

    Veterinarians don’t pull dogs with kennel cough from Iditarod:

    “For now, his [Lance Mackey] dogs have what he believes are the early symptoms of kennel cough. A wheel dog named Pat “hasn’t eaten probably a pound of food since the starting line,” he said.

    At about 8:30 p.m., hours before Mackey was scheduled to leave, he stood in the dark as a vet checked one of his leaders, Rev. The dog made a hacking sound.”

    – Kyle Hopkins, Anchorage Daily News, March 9, 2011, Takotna checkpoint

    Kyle Hopkins: “So you have a little bit of illness also on your team?”

    Sebastian Schnuelle: “Oh yah, for sure I had that stupid kennel cough like big time. It started like two days before the race.”

    Kyle Hopkins: “Do you think they got it on the Quest?”

    Sebastian Schnuelle: “Oh yeah for sure, Ken [Anderson] had it, Hans [Gatt] had it. So I guess we three kind of stuck together there. So I guess we all got it.”

    – iditablog, Anchorage Daily News, March 9, 2011, Takotna checkpoint – Kyle Hopkins is a reporter for the Anchorage Daily News. – The 2011 Iditarod started on March 5.

    “As the race got underway, [Hans] Gatt said about half of his team was battling kennel cough.”

    – Jill Burke, Alaska Dispatch, March 9, 2011

    “Disappointment in the Iditarod. After contacting Kennel Cough before the race I had hopes the team would recover in time. Unfortunately only some of them did. By McGrath I was down to 9 dogs from the 16 that started, due to a combination of illness & injury. The remaining dogs were still showing strong symptoms of the cough, and with only one leader remaining I decided it was in the best interest of the dogs to end the race at this point.”

    – Iditarod musher Gerry Willomitzer, www.gerrywillomitzer.com, March, 2011

    “The run from TAKOTNA to OPHIR is short, but hilly. I gauge my team by the time interval we take to cover this distance. A good time is 2 and a half hours. I always think back to my first Iditarod. My entire dog team had kennel cough and were moving slowly right here.”

    – Aliy Zirkle, SP Kennel Dog Log, Iditarod Trail Notes, 2010 – According to the Iditarod’s website, Aliy Zirkle’s first Iditarod was in 2001.

    “Jamie [Nelson] said her team had come down with what the vets thought was kennel cough.”

    – Veterinarians put sick dogs on cephalosporin (an antibiotic) and let them keep racing:

    Lance Mackey: “I’m going to take them to Ophir and see what happens.”

    Veterinarian: “I would say at this point since you haven’t had them on cephalo[sporins], give them at least 24 hours…”

    – Randi Weiner, The Journal News, March 31, 2011

    Difficult to prevent Iditarod dogs from getting stomach ulcers:

    “Under actual racing conditions, famotidine was not sufficiently effective in preventing severe EIGD [exercise-induced gastric disease]. A further study was then conducted, which compared the efficacy high-dose famotidine (40 mg PO BID/~25 kg dog) with omeprazole (20 mg PO SID/~25 kg dog) in preventing EIGD under racing conditions. This study showed that, with carefully timed administration, near the conclusion of a long exercise bout during which minimal snacking has occurred, omeprazole is more effective in reducing the number and severity of gastric lesions in racing sled dogs than famotidine. If an additional 30 min is allowed to pass prior to feeding the dog, efficacy can approach 100% in preventing clinically significant lesions during even the most strenuous exercise events.”

    Serious stomach ulcers from racing as little as 100 miles:

    “I reviewed a recent study about gastrointestinal damage resulting from training and racing sled dogs which appeared in a well-respected veterinary journal. Two of the more interesting conclusions presented were:

    Training alone, without the additional stress of racing, results in significant, measurable gastrointestinal damage.

    Serious stomach ulcers and other significant, measurable gastrointestinal damage results from racing as little as 100 miles.”

    High incidence of ulcers in Iditarod dogs:

    “A pilot study of dogs that were either dropped from the 2000 Iditarod Sled Dog Race because of illness or that finished the race indicated that, approximately 5 days after competing, 10 of 28 dogs (35%) had endoscopic evidence of gastric ulceration, erosion, or hemorrhage. The next year, an endoscopic study of 73 dogs participating in the 2001 Iditarod race was performed in order to evaluate a larger population of dogs. Data from 70 of these dogs could be used; 34 (48.5%) had ulceration, erosion, gastric hemorrhage, or some combination of these findings. When this group of 70 dogs was compared retrospectively to a control group of 87 dogs presented to the Texas A&M University (TAMU) Veterinary Medical Teaching Hospital, the Iditarod sled dogs had a significantly higher prevalence (P = .049) of gastric lesions.”

Convention is that we accept a p value of 0.05 or below as being statistically significant.” – Bandolier, a journal about evidence-based healthcare, written by Oxford scientists, website article

    – High incidence of ulcers in Iditarod dogs caused by NSAIDs:

    Many Iditarod dogs have gastric ulcers and some have died from this condition. Ulcers predispose the dogs to vomiting. Normally, the trachea closes the airway so that foreign material does not enter the lungs. But because these dogs run at such high speeds for such a long period of time, they cannot stop gasping for air despite the vomiting. Consequently, dogs inhale the vomit into their lungs which causes suffocation and death.

    According to Michael Matz, a highly regarded expert in gastrointestinal disorders in small animals, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) is the most common cause of gastrointestinal ulceration in small animals (Kirk’s Current Veterinary Therapy XII- Small Animal Practice). Aspirin, ibuprofen, naproxen are just some of the NSAIDs that cause ulcers. These drugs reduce swelling, inflammation, relieve pain and fever, which allows the dogs to run farther and faster. Unfortunately, some dogs pay with their lives for the use of these drugs.

    – High incidence of ulcers in Iditarod dogs caused by stress:

    Andrea Floyd-Wilson: “What are they thinking is the cause that these dogs are getting, and it really seems like a very high number of them do get ulcers?”

    Dr. Paula Kislak: “That’s correct. And it’s almost universally known to be as a result of the amount of stress that they endure and the medication they’re given. Just like people under extreme stress develop ulcers. This is the exact same etiology or cause in these dogs as well.”

    – On February 23, 2003, Andrea Floyd-Wilson, the host of All About Animals Radio Show, interviewed Margery Glickman, Director of the Sled Dog Action Coalition, and Paula Kislak, DVM, President of the Association of Veterinarians for Animal Rights.

    – Sustained strenuous exercise associated with 61 percent ulcer rate postrace compared to zero percent prerace:

    “Sustained strenuous exercise was associated with an increased frequency of gastric erosions or ulcerations seen endoscopically (0% prerace versus 61% postrace). A significant postrace increase occurred in the median lactulose to rhamnose ratio in both serum and urine (0.11 versus 0.165, P = .0363; 0.11 versus 0.165, P = .0090, respectively). No significant differences were found in median serum or urinary sucrose concentrations when pre- and postrace values were compared. No correlation was found between visible gastric lesions and the concentration of sucrose in serum or urine samples obtained 4-5 hours after administration of the sugar solutions. We conclude that sustained strenuous exercise is associated with increased intestinal permeability, but the sucrose permeability test as we performed it did not correlate with visible gastric lesions.”

    Dogs have extreme loss of weight during 1000-mile endurance race:

    A study of dogs in a 1,000-mile endurance race found that these dogs suffered from extreme weight loss. “The precipitous weight loss observed, which is also observed in human athletes to a lesser degree shows severe negative energy balance in these endurance dogs. Body condition scoring suggests a 7–10% decrease in weight with each one point drop in BCS; therefore the dogs in our study lost a mean 14–20% of their individual body weight during the course of the race.”
