Feeding & Nutrition

Most dog food advice is written for the couch-dwelling pet, and that's fair — most dogs are couch dwellers. But take a Border collie doing three hours of stock work, a sled dog covering forty miles, or a hunting retriever swimming cold rivers all day, and the rules quietly change. A working dog isn't a lazy dog that moved more. It's a different metabolic animal, and feeding it like the lab on the sofa will leave it thin, tired, and underperforming.

The first shift is energy density. A hard-working dog can burn two, three, even four times its resting calories, and it can't eat four times the volume — its stomach simply won't hold that much kibble. So the food has to pack more punch per cup. That means fat, and lots of it. Where a pet maintenance diet might run 12 to 16 percent fat on a dry basis, working and sled-dog diets routinely sit at 20 to 30 percent or higher. Fat is the most concentrated energy source there is, more than double the calories per gram of protein or carbohydrate, and it's exactly what a dog burning all day needs.

Protein stays high too, not just for muscle but because working dogs turn over tissue constantly and need the amino acids to repair it. But the old idea that you should carb-load a dog like a marathon runner is wrong for the species. Dogs are superb at burning fat for sustained effort — better than we are — and a fat-adapted working dog tends to have steadier energy than one riding a carb spike and crash. That's why you'll see mushers feeding salmon-based, fat-rich diets rather than grain-heavy ones.

Timing around exercise is where owners mess up most. A big meal right before hard work is a bad idea: the gut is competing with the muscles for blood flow, and a full stomach during sprint work raises the risk of a painful stomach condition in deep-chested breeds. The practical routine most handlers use is to feed the main meal after work, when the dog is cooling down, and give a smaller meal or snack well before effort — a few hours prior, never right before. Post-work feeding also helps with recovery, when the body is primed to take in nutrients.

Hydration deserves more respect than it gets, because working dogs lose enormous amounts of water and electrolytes through panting and exertion, especially in heat or cold-dry air. A dehydrated working dog falters fast and risks serious trouble. The trick is not just offering water but encouraging steady intake — fresh, unfrozen sources on winter runs, shaded water stops on summer ones. Some handlers use a slightly salty broth or electrolyte solution for multi-hour efforts, but plain clean water does the job for most. Never let a hot, panting dog gulp huge amounts at once; small, frequent drinks beat a tankful that comes back up.

Body condition is the real-time report card. You should be able to feel ribs easily but not see them; a working dog carrying a little more condition going into hard season has reserves to spend, while one already lean needs more food, not less. Weigh regularly and adjust. A dog dropping weight mid-season is telling you the diet isn't keeping up, and ignoring that slides into exhaustion and injury. The feeding amounts on the bag are a starting point written for an average pet, not your athlete.

Cold changes the math too. A dog working in freezing temperatures burns extra calories just to stay warm, and the easy weight you maintained in autumn melts off in January if the food doesn't rise with it. Mushers talk about this constantly — the same dog needs more in a minus-twenty run than a cool autumn one, and they learn the dog's condition by hand, not by the scale alone. Heat flips the problem: a dog that won't eat in summer heat is often just too warm, and splitting meals into cooler early-morning and late-evening feedings keeps intake up when the middle of the day is unusable. Reading the season is part of the job.

There are real mistakes worth naming. Suddenly switching to a rich performance diet the morning of a big event upsetts the gut — transition over a week like any food change. Assuming a puppy can do adult working-dog loads burns it out and harms growing joints; conditioning builds gradually over months and years. And treating every high-drive pet dog as a working dog just because it's energetic leads to an overweight, over-fed couch cheetah. "Working" means actual sustained output, not zoomies in the backyard.

The satisfying part is watching it click. A dog fed for the work it does — calorie-dense, fat-forward, timed around effort, watered constantly — finishes strong instead of fading. The food stops being background and becomes the difference between a dog that's merely along for the trip and one that's genuinely doing its job. Get the fuel right, and the engine runs the way it was built to.
