Why 30/20 works for real work
Endurance work burns fat efficiently; 20% dietary fat doubles the energy density of maintenance formulas and spares muscle protein. The 30/20 ratio originated in sled-dog research and remains the field standard. Pet “active breed” owners routinely overfeed it — at 475 kcal/cup, a sedentary 40 lb dog needs barely 2 cups, and most owners pour 3.
Who should skip it
Neutered couch dogs: the calorie density makes obesity almost automatic. Dogs with pancreatitis history: 20% fat is a relapse trigger (our low-fat ladder file). Everyone else gets a legitimate, trial-backed performance ration at mid-market price — our working-dog feeding file covers seasonal rationing around it.
FAQ
Can I feed Sport 30/20 to my regular pet dog?
Technically yes, practically risky: at 475 kcal/cup, obesity comes fast. Maintenance formulas fit pets better.
Is the poultry by-product meal a problem?
No — it is a concentrated, digestible protein source. The formula’s field results outweigh the label aesthetics.
