Collie Calorie Calculator — How to Use It
Enter your Collie's current weight and activity level above. The calculator uses the Modified NRC Resting Energy Requirement (RER) formula: calories = 70 × (body weight in kg)^0.75, then multiplied by an activity factor. This is the same method recommended by the American College of Veterinary Nutrition.
A reliable daily calorie calculator built specifically for Collies.
How Many Calories Does a Collie Need?
The Collie is best known as Lassie, the fictional TV hero — and the real breed lives up to the legend. Originally bred in Scotland and Northern England as a sheepherding dog, Collies are highly intelligent, graceful, and deeply devoted to their families. They excel at obedience, agility, and herding trials. Their thick double coats require significant grooming maintenance. An important health note: many Collies carry the MDR1 gene mutation, making them sensitive to certain common drugs.
A Collie in the typical weight range of 60–75 lbs needs roughly 1268–1450 calories per day at moderate activity. Dogs that get 90+ minutes of vigorous exercise daily need the higher end of this range. Neutered dogs typically need 15–20% fewer calories than intact dogs of the same weight and activity level.
Collie Feeding Guidelines by Life Stage
Puppies (under 12 months): Collie puppies need 2–3× the adult calories per pound of body weight to fuel rapid growth. Feed 3–4 small meals per day until 6 months, then reduce to twice daily. Never restrict puppy calories — growth stage nutrition is critical for bone and joint development.
Adults (1–7 years): This is when the calorie calculator is most reliable. An average adult Collie weighing 67 lbs needs approximately 1268 kcal/day at moderate activity — roughly 3.4 cups of a standard 380-kcal/cup kibble, split into two meals.
Seniors (7+ years): Most senior dogs need 20–30% fewer calories than adults due to reduced activity and slower metabolism. However, Collies with joint issues may also benefit from higher-quality protein to maintain muscle mass. Talk to your vet before reducing portions significantly.
Frequently Asked Questions
Q: How many cups of food should I give my Collie per day?
A: For a 67-lb adult Collie at moderate activity, aim for 3.4–3.9 cups per day of a standard kibble (around 380 kcal/cup). Always check the specific caloric density on your dog food bag and adjust accordingly.
Q: My Collie is gaining weight. Should I reduce portions?
A: Start by reducing portions by 10% and reassessing after two weeks. Make sure treats aren't adding hidden calories — treats should account for no more than 10% of daily calories. If your dog is still gaining weight, consult your veterinarian to rule out thyroid issues.
Q: Does exercise affect how many calories my Collie needs?
A: Absolutely. A Collie getting 90 minutes of vigorous daily exercise needs roughly 20–30% more calories than one who gets only light walks. The activity multiplier in this calculator accounts for that difference.
