🐕 狗粮喂食量计算器Dog Food Calculator
按狗狗体重和生命阶段计算每日能量需求（静息能量 RER = 70 × 体重^0.75，乘以生命阶段系数，主要系数参照 AAHA 2021 指南），再根据狗粮包装上的热量算出每天喂多少克或多少杯。Work out how much to feed your dog: daily calories from resting energy (RER = 70 × weight^0.75) times a life-stage factor (main factors from the 2021 AAHA guidelines), then grams or cups per day from the calorie content on the bag.

如何使用「狗粮喂食量计算器」？How do I use the Dog Food Calculator tool?
在「狗粮喂食量计算器」中，填写「体重（减重模式填目标体重）」、「体重单位」、「生命阶段」、「狗粮热量」、「热量单位」等参数，结果会随输入实时计算并显示在下方。In the Dog Food Calculator: Fill in "Weight (target weight in weight-loss mode)", "Weight unit", "Life stage", "Food calories", "Calorie unit"; results are recalculated instantly as you type.
计算公式？What formula is used?
静息能量需求 RER = 70 × (体重 kg)^0.75 kcal/天，每日能量需求 = RER × 生命阶段系数。系数来源：AAHA《2021 犬猫营养与体重管理指南》Box 1——已绝育成犬 1.4–1.6（本工具取 1.6）、未绝育成犬 1.6–1.8（取 1.8）、幼犬 4 个月以下 3.0、4 个月以上 2.0；减重按目标体重的 RER × 1.0。活动少（1.2）、老年犬（1.4）和中等强度工作犬（3.0）是常用经验值（示例值），没有统一标准。Resting energy requirement RER = 70 × (body weight in kg)^0.75 kcal/day; daily need = RER × a life-stage factor. Sources: 2021 AAHA Nutrition and Weight Management Guidelines, Box 1 — neutered adult 1.4–1.6 (the tool uses 1.6), intact adult 1.6–1.8 (uses 1.8), puppy under 4 months 3.0, 4 months and older 2.0; weight loss uses RER at the target weight × 1.0. The inactive (1.2), senior (1.4) and moderate working dog (3.0) factors are common rules of thumb (example values) with no single standard.
狗粮热量在哪里看？Where do I find the food's calories?
包装上通常标有“代谢能 kcal/kg”，有的还标“kcal/杯”。不同产品差异很大，请以包装上的数值为准。切换「热量单位」只改变数字的含义，不会换算数值，因为每杯的重量取决于狗粮的密度。The bag lists metabolisable energy in kcal/kg and often kcal per cup. Products differ a lot, so use the number on your bag. Switching 'Calorie unit' changes what the number means but does not convert it, because the weight of a cup depends on the food's density.
零食要算进去吗？Do treats count?
要。零食一般不超过每日热量的 10%，并从正餐中相应扣除。Yes. Keep treats under about 10% of daily calories and reduce meals accordingly.
结果可以代替医生的建议吗？Can this replace medical advice?
不能。「狗粮喂食量计算器」基于常用公式给出估算，个体差异较大，如有健康问题请咨询医生或专业人士。No. The Dog Food Calculator gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
