Daily Food Amount vs Pet Weight
Formula
## Pet Food Calculation Feeding amounts depend on your pet's weight, age, and activity level. The resting energy requirement (RER) formula provides a starting point. ### Formula **RER (kcal/day) = 30 x Weight(kg) + 70** **Daily Calories = RER x Activity Multiplier** Activity multipliers: Inactive/senior (1.1x), Moderate (1.4x), Active (1.7x). One cup of dry dog food averages about 400 calories. Always adjust based on body condition.
Esempio Risolto
A 40 lb moderately active dog eating $3/lb food.
- 01Weight in kg = 40 / 2.205 = 18.14 kg
- 02RER = 30 x 18.14 + 70 = 614 kcal
- 03Adjusted = 614 x 1.4 = 860 kcal
- 04Daily cups = 860 / 400 = 2.1 cups
- 05Monthly cost = 2.1 x 0.25 lb x 30 x $3 = $47.25
Domande Frequenti
How do I know if my pet is the right weight?
You should be able to feel (but not see) ribs. From above, there should be a visible waist. Your vet can assess body condition score on a 1-9 scale (4-5 is ideal).
Should I feed once or twice a day?
Most adult dogs do well with twice-daily feeding. Cats can be fed 2-3 times or free-fed dry food (watch for overeating). Puppies need 3-4 meals until 6 months.
Wet vs dry food?
Both can be nutritionally complete. Wet food has more moisture (good for hydration) but costs more per calorie. Dry food is convenient and helps dental health. Many owners mix both.
