Border Collie portions by weight
| Adult weight | RER | Daily target | Kibble / day | Cups / day | Per meal (×2) | Raw / day |
|---|---|---|---|---|---|---|
| 14.0 kg | 507 kcal | 811 kcal | 197 g | 2.0 | 99 g | 350 g |
| 17.0 kg | 586 kcal | 938 kcal | 228 g | 2.3 | 114 g | 425 g |
| 20.0 kg | 662 kcal | 1,059 kcal | 258 g | 2.6 | 129 g | 500 g |
Neutered adult (×1.6), kibble at 370 kcal/100 g, 10% treat allowance removed. Raw at 2.5% of body weight (size-correct rate). Cups ≈ grams ÷ 100 (typical kibble — weigh in grams for accuracy).
Worked example: a 17.0 kg Border Collie
A 17.0 kg adult Border Collie (neutered): RER 586 × 1.6 = 938 kcal − 94 kcal treats ÷ 3.7 kcal/g = 228 g — that is 114 g per meal, twice a day. The same arithmetic runs in the calculator above: change the weight or the life stage and every number follows.
Border Collie puppy feeding by age
| Age | Factor | Meals / day | Note |
|---|---|---|---|
| Under 4 months | ×3.0 | 3–4 | On current weight — weigh every 2 weeks |
| 4–8 months | ×3.0 → ×2.0 (taper) | 3–4 | Factor falls smoothly — weigh every 2 weeks |
| 8–12 months | ×2.0 | 3 | 3 meals; 2–3 from 6 months |
| 12 months to adult | ×1.6–1.8 | 2 | Adult factor from 12–14 months |
Factors multiply RER on the puppy's current weight, not adult weight. Large and giant breeds keep the growth factors until 12–14 months.
Feeding notes for the Border Collie
Athletic medium breeds (herders, pointers, retrievers in work) regularly need 2.0–2.5×. The pet default will underfeed a dog in daily training — select the active stage honestly and re-weigh every two weeks.
What makes feeding a Border Collie different: The highest-energy breed on this site: a working Border Collie honestly needs the active factor, and a day of training treats can quietly add a quarter of the daily calories. Count every reward inside the number, and re-weigh every two weeks in season.
Health, treats and the senior years: When the work stops, the factor has to stop with it: a retired Collie kept on the working number gains fast. Use food puzzles and training rewards from the meal ration itself, so the dog stays busy without the day's total moving — a bored Collie invents its own entertainment, usually involving food.
Training, treats and everyday feeding: Border Collies are the smartest breed on this site, so a puzzle feeder or scatter feeding is worth more than a bigger bowl — it turns a meal into a job. Training treats are the leak: a day of rewards can add a quarter of the daily calories, so pay the dog from the meal ration itself, and re-weigh every two weeks in season.
Weight & condition for the Border Collie: Border Collies are the highest-energy breed on this site, and the factor honest to their routine matters more than the breed name: a working Collie needs ×2.0–2.5, a pet Collie on two walks needs ×1.6. A 17.0 kg Collie moves from about 938 kcal/day to about 1,172 kcal/day between the two — weigh every two weeks in season, because the routine changes with the work.
Body condition check: A number on the scale is not a body condition. Score the dog on the 9-point scale and aim for 4–5 — ribs palpable through a thin fat layer, waist visible from above, abdomen tucked when viewed from the side. Can't feel the ribs? Feed 10% under the table. Ribs plainly visible? Feed 10% over it.
Puppies of this size class reach adult factors at about 12–14 months; until then, growth portions follow the puppy factors (×3.0 under 4 months, tapering to ×2.0 by 8 months) on current weight, recalculated every two weeks. Individual dogs vary by up to ±50% from any formula — the scale and your hands on the ribs outrank this table.

Border Collie feeding questions
How much food should a Border Collie eat per day?
Across the full adult weight range (14–20 kg), a Border Collie needs about 811–1,059 kcal/day — 197–258 g of typical kibble (370 kcal/100 g) after the 10% treat allowance is removed — depending on weight, sex and activity. A typical adult at the middle of the range (17.0 kg) needs about 938 kcal/day, roughly 228 g, split over 2 meals.
How many meals a day should a Border Collie eat?
Two meals a day suits a Border Collie: about 114 g per meal from a daily total of 228 g (938 kcal) for a 17.0 kg adult — served in a food puzzle or scattered, not in a plain bowl. A border collie that eats in ninety seconds and looks for work has not been fed too little; it has been fed too fast. Training rewards are the leak in this breed, so pay the dog from its own ration and re-weigh every two weeks in season.
How many cups of food does a Border Collie need per day?
About 228 g/day is roughly 2.3 cups at the typical density of 100 g per cup — but cups vary by up to 40% between kibbles, so weigh the grams once and the question disappears. A cup is a volume; grams are the portion. Split over two meals that is about 1.1 cups per meal — still worth weighing once, because your cup and your kibble are not the standard ones.
How do I switch a Border Collie to a new food?
Over 7 days: 25% new food for 2 days, 50% for 2 days, 75% for 2 days, then 100% — keeping the total daily grams at the number on this page throughout. If stools loosen, hold at the current mix for an extra day or two before moving on. If your dog has a sensitive stomach, allow 10–14 days instead of 7.
How much should a Border Collie puppy eat?
Medium puppies reach adult factors at about 12–14 months. Growth portions follow ×3.0 (under 4 months) tapering to ×2.0 by 8 months, on current weight, recalculated every two weeks; growth spurts change the answer monthly.
How much raw food does a Border Collie need?
At the size-correct BARF rate of 2.5% of ideal body weight, a 17.0 kg Border Collie eats about 425 g of raw food per day — split 70% muscle meat, 10% raw edible bone, 5% liver, 5% other organ, 10% vegetables and fruit on the BARF model.
How does feeding a Border Collie change as they age?
From about 12–14 months a Border Collie counts as fully adult; the senior shift usually arrives years later, when activity and muscle mass fall. The calculator's senior factor (×1.4 instead of ×1.6) trims a 17.0 kg Border Collie from 938 to about 820 kcal/day — roughly 200 g of typical kibble. Make the change gradually and judge by body condition, not birthdays alone: a still-active older Border Collie may hold condition on the adult number.
How much should a working Border Collie eat?
Use the active factor: a 17.0 kg Collie in daily training or farm work needs about 1,172 kcal/day at ×2.0 — roughly 285 g of kibble — versus 938 kcal at the pet default. If the dog is losing condition on the active factor, step up in 10% increments with two-week weigh-ins rather than jumping factors.
Do Border Collies need more food in summer?
Only if the work increases — trial season, longer days, more training. The portion follows the routine, not the season: a pet Collie with the same walks needs the same 228 g/day all year. Change the factor when the workload changes, and re-weigh two weeks later.
