Rhodesian Ridgeback portions by weight
| Adult weight | RER | Daily target | Kibble / day | Cups / day | Per meal (×2) | Raw / day |
|---|---|---|---|---|---|---|
| 32.0 kg | 942 kcal | 1,507 kcal | 367 g | 3.7 | 183 g | 800 g |
| 36.5 kg | 1,039 kcal | 1,663 kcal | 405 g | 4.0 | 202 g | 912 g |
| 41.0 kg | 1,134 kcal | 1,815 kcal | 441 g | 4.4 | 221 g | 1,025 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 36.5 kg Rhodesian Ridgeback
A 36.5 kg adult Rhodesian Ridgeback (neutered): RER 1,039 × 1.6 = 1,663 kcal − 166 kcal treats ÷ 3.7 kcal/g = 405 g — that is 202 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.
Rhodesian Ridgeback 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 15–18 months |
Factors multiply RER on the puppy's current weight, not adult weight. Large and giant breeds keep the growth factors until 15–18 months.
Feeding notes for the Rhodesian Ridgeback
A working large breed is an athlete with a big tank: 2.0–2.5× is normal in season. Split into two meals and avoid hard exercise on a full stomach — large, deep-chested dogs are the gastric-dilation risk group.
What makes feeding a Rhodesian Ridgeback different: Ridgebacks are lean, muscular athletes that hold condition on surprisingly little food for their size — they are not a breed to feed up. Judge by the waist and ribs, and use the active factor only for dogs in real daily work.
Health, treats and the senior years: Ridgebacks are prone to hip problems, and extra weight makes every step harder — a lean Ridgeback moves better for longer. In old age, the appetite stays young while the joints don't, so let the scale and the ribs decide the portion, never the begging.
Training, treats and everyday feeding: Ridgebacks are lean athletes that hold condition on surprisingly little food, so the factor should follow the workload — and food is the best training currency for this breed. Use part of the daily ration as rewards, so the dog works for its dinner instead of eating extra on top of it.
Weight & condition for the Rhodesian Ridgeback: Ridgebacks are lean, muscular athletes that hold condition on surprisingly little food for their size — they are not a breed to feed up. Judge by the waist and ribs, and use the active factor only for dogs in real daily work. A Ridgeback that looks heavy is usually just fat: the breed is meant to look like a runner, not a bodybuilder.
Body condition check: Weigh the dog, then look at the dog: the 9-point body condition scale wants a 4–5, with ribs felt rather than seen, a waist that narrows behind the ribs, and a belly that tucks up from the side. If the ribs have vanished under fat, cut the table portion by 10%; if they show clearly, add 10%.
Puppies of this size class reach adult factors at about 15–18 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.

Rhodesian Ridgeback feeding questions
How much food should a Rhodesian Ridgeback eat per day?
Across the full adult weight range (32–41 kg), a Rhodesian Ridgeback needs about 1,507–1,815 kcal/day — 367–441 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 (36.5 kg) needs about 1,663 kcal/day, roughly 405 g, split over 2 meals.
How many meals a day should a Rhodesian Ridgeback eat?
Two meals a day suits a Rhodesian Ridgeback: about 202 g per meal from a daily total of 405 g (1,663 kcal) for a 36.5 kg adult. A ridgeback that holds condition on surprisingly little food is not being underfed — it is a ridgeback — so judge by the ribs and the scale, not by the size of the bowl. Training rewards should come from the ration, not on top of it.
How many cups of food does a Rhodesian Ridgeback need per day?
About 405 g/day is roughly 4.0 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. At 405 g a day, a 10% scooping error is about 40 g — a small dog's entire meal — so weighing matters more, not less, as portions grow.
How do I switch a Rhodesian Ridgeback 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 Rhodesian Ridgeback puppy eat?
Large-breed puppies grow for 15–18 months — and lean growth is the goal: excess calories accelerate the frame faster than joints can follow. Use ×3.0 under 4 months, tapering smoothly to ×2.0 by 8 months, on current weight, and keep the puppy visibly slim.
How much raw food does a Rhodesian Ridgeback need?
At the size-correct BARF rate of 2.5% of ideal body weight, a 36.5 kg Rhodesian Ridgeback eats about 912 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 Rhodesian Ridgeback change as they age?
From about 15–18 months a Rhodesian Ridgeback 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 36.5 kg Rhodesian Ridgeback from 1,663 to about 1,455 kcal/day — roughly 354 g of typical kibble. Make the change gradually and judge by body condition, not birthdays alone: a still-active older Rhodesian Ridgeback may hold condition on the adult number.
Is my Ridgeback underweight?
Probably not: Ridgebacks are meant to look lean and muscular, with ribs faintly visible and a clear waist. If the ribs are easy to feel under a thin cover, the 1,663 kcal/day for a 36.5 kg adult is right. Only add food if the hip bones or spine show clearly — and remember this breed holds condition on surprisingly little food for its size, so the scale and the waist matter more than the eye.
How much should a Ridgeback eat when it is not working?
Drop to the standard factor: a 36.5 kg adult on ×1.6 needs about 1,663 kcal/day — roughly 405 g of kibble. The active factor (about 2,079 kcal/day at ×2.0) is only honest for dogs in real daily work, and a Ridgeback kept on the working number in the off-season will gain fast.
