Eating & Drinking for Iditarod Dogs
By Sanka W. Dog
Canine athletes in the Iditarod need to consume enormous amounts of food and drink plenty of water. During the race each dog will need to ingest roughly 12,000 calories per day. A human would have to down 50 Big Macs to equal that many calories! Just as important as food is water consumption. Food and water go hand in hand for optimal athletic performance.
During the summer when the dogs aren’t in training, a 50-pound dog requires about 1,500 calories and 1-½ quarts of water each day. During this time known as maintenance, adult dogs are fed once a day. But as temperatures drop and the dog’s workload increases, so do their calorie and hydration requirements. At the peak of its performance season in cold temperatures, a dog may need up to six times its off-season calorie requirement and up to six quarts of water. This is accomplished in multiple feedings each day.
Mushers must see to it that their dogs get a balanced diet with the proper amounts of vitamins, minerals, protein and fat along with adequate water. Problems associated with improper diet become noticeable over time while deficiencies in hydration affect a dog’s health immediately. Dry dog foods provide a balanced diet but a dog can’t eat enough “kibble” to consume the number of calories necessary for long distance training and racing.
According to the Sled Dog Care Guidelines published by Mush with P.R.I.D.E., “The relative caloric density of fat and its superiority as a fuel for dogs is why many mushers supplement their dogs’ basic ration with extra fat during periods of cold weather and/or heavy work.” So while on the trail, mushers supplement the dry dog food or kibble with high calorie meat and fat. Very different from humans, sled dogs during peak season actually require and perform very well on a diet that consists of 60% fat!
Sled dogs on the Iditarod trail can expect a feeding and hydration regimen similar to what is described here. As soon as a team comes into a checkpoint a snow hook is set ahead of the leaders and another behind the sled. Once the team is secure, the dog’s booties are removed, the tug lines unhooked and straw is spread out. Now it’s time to eat and drink – the dogs are given a bowl of water and a bowl of kibble. The musher then cooks the team a warm meal consisting of more kibble and lots of meat mixed in water. When a team stays in a checkpoint for 6 hours, as is most often the case if a musher chooses to follow a 6-hour run rest schedule, the dogs will receive another brothy meal about an hour and a half before leaving. Typically this brothy concoction is a sloppy combination of meat scraps cooked in a lot of water. Some mushers refer to this as slurry or baited water. Baiting warm water with dry food, cooked fish, meat or garlic powder is a great way to encourage dogs to drink.
Just like students, dogs enjoy and look forward to snacks! Mushers like Martin Buser divide the 6 hour run time in half and stop to snack the dogs 3 hours into the run. Other mushers go heavier on the snacks, snacking after 2-½ hours and every hour there after until reaching the next checkpoint. Most often the snacks are frozen fish (salmon & smelt) or frozen meat (beaver, mink, venison or other ground game). These frozen snacks are a source of both calories and water. Snacking depends on the weather, the colder it is the more snacks the dogs receive.
Mushers are continually monitoring the weight of their dogs during the race. A well-conditioned sled dog should be lean and muscular but NOT skinny. The Mush with P.R.I.D.E. Guidelines indicate that the ribs, spine and hip bones of a dog should not be buried under an inch of fat, nor should they protrude but they should be easy to feel. Over weight athletes get hurt from the strain of carrying “extra” weight. Underweight athletes will perform adequately early in the race but will decline in performance as the miles add up. Mushers will drop dogs that are getting too thin during the race. Whole teams have “scratched” because the dogs haven’t been able to maintain a healthy weight on their trail diet.
Because hydration is critically important, not only for sled dogs but humans too, here is a little more information. The Mush with P.R.I.D.E. Guidelines tell us that dogs get water in 3 ways – drinking it directly, eating foods that contain water and through metabolism. Water is lost through water vapor in the breath, feces and urine. Activity increases water loss for athletes. When a dog runs, it exhales more air than when at rest resulting in greater water loss. Increased food intake during racing and training results in increased fecal output and metabolic waste that has to be filtered through the kidneys creating more water loss. Increase in water loss during activity increases water requirements for both dogs and mushers.
Veterinarians use two tests to check dogs for proper hydration. The first test evaluates hydration by using the skin. When pinched and lifted, the skin between the shoulders of a well hydrated dog, will “snap” back within 1 or 2 seconds. The second test is a gum test. The white spot made by pressing on a pink area of a dog’s gums should disappear in one second or less. As mentioned before, dehydration can be serious and is monitored closely.
Now you should have a good idea of how dogs eat and drink while on the Iditarod Trail. Being that I’m such a young dog, only 9 months old, I had to ask several of my friends (vets, mushers, handlers & dogs) for their best practices to give you accurate information. My friends who contributed their knowledge for this story are Sue Allen (No Snow Kennel) of Houston, AK; Martin Buser (Happy Trails Kennel) of Houston, AK; Ron Cortte (Quietwood Kennel) of Tomahawk, WI; Tim Calhoun (Seek Adventure Kennel) of Tomahawk, WI; Seek Adventure dogs – Willie, Opal, Jimmy, Lil Mac, Coffee & Judo; Dr. Sonny King of Spartanburg, SC; Jeff King (Husky Homestead) of Denali, AK; and the authors of Mush with P.R.I.D.E. Sled Dog Care Guidelines.
Stay tuned for more stories about puppies, dogs and Iditarod. I hope you’ll watch Sue Allen as she runs Iditarod with Martin Buser’s puppy team – that’s the team I’m going to be watching. I want to see how those puppies do. Sue says the major goal for a puppy team is to have fun on the trail and get to know the trail. Sue is a veteran of the 2004 Iditarod. For sure, those young dogs will have fun with her on the trail.
I have to tell you, I’ve started in harness a couple of months ago and I LOVE TO PULL!
