About AAFCO Standards: The Association of American Feed Control Officials (AAFCO) establishes nutrient profiles that ensure complete and balanced nutrition for dogs at different life stages. Foods meeting these standards are labeled as suitable for "growth and reproduction" (puppies, pregnant/nursing dogs) or "adult maintenance."

Important Notes:

  • All values are expressed on a dry matter basis (moisture removed)
  • Puppy foods must meet the higher "growth and reproduction" standards
  • If a food meets puppy standards, it automatically meets adult standards
  • Large breed puppies have additional calcium restrictions (max 1.8%)

Essential Amino Acids (Minimum Requirements)

Amino Acid Growth & Reproduction Adult Maintenance Unit
Arginine 0.62% 0.51% % dry matter
Histidine 0.22% 0.18% % dry matter
Isoleucine 0.45% 0.37% % dry matter
Leucine 0.72% 0.59% % dry matter
Lysine 0.77% 0.63% % dry matter
Methionine + Cysteine 0.53% 0.43% % dry matter
Phenylalanine + Tyrosine 0.89% 0.73% % dry matter
Threonine 0.58% 0.48% % dry matter
Tryptophan 0.20% 0.16% % dry matter
Valine 0.48% 0.39% % dry matter

Life Stage Feeding Guidelines

Puppy Stage (0-12 months)

  • Energy Needs: 2-3× adult maintenance (rapid growth phase)
  • Protein: Minimum 22.5% (supports muscle development)
  • Fat: Minimum 8.5% (brain development, energy)
  • Feeding Frequency: 3-4 meals/day (0-4 months), 2-3 meals/day (4-12 months)
  • Key Nutrients: DHA for brain development, calcium/phosphorus for bones
  • Special Note: Large breed puppies need controlled calcium (max 1.8%) to prevent skeletal issues

Adult Stage (1-7 years)

  • Energy Needs: 1.6-1.8× RER (maintenance phase)
  • Protein: Minimum 18% (muscle maintenance)
  • Fat: Minimum 5.5% (energy, coat health)
  • Feeding Frequency: 1-2 meals/day
  • Focus: Weight management, dental health, joint support for active dogs

Senior Stage (7+ years)

  • Energy Needs: Reduced by 15-20% (slower metabolism)
  • Protein: 25-30% high-quality protein (prevent muscle loss)
  • Fat: 12-15% (reduced but adequate)
  • Key Additions: Glucosamine/chondroitin (joints), antioxidants (cognitive health), omega-3 (inflammation)
  • Monitor: Kidney function (phosphorus control), weight gain tendency

Pregnant/Nursing Dogs

  • Energy Needs: 3-8× RER (depending on litter size)
  • Protein: 25-30% (fetal development, milk production)
  • Fat: 15-20% (energy-dense nutrition)
  • Feeding Strategy: Free-choice feeding during lactation
  • Supplements: Folic acid, iron, calcium (vet supervised)

Activity Level Multipliers

Activity Level Description Multiplier
Low Indoor dogs, minimal exercise, sedentary lifestyle 1.2-1.4×
Moderate Daily walks (30-60 min), occasional play 1.6-1.8×
High Active dogs, running, agility, frequent play 2.0-2.5×
Very High Working dogs, sled dogs, competitive athletes 3.0-5.0×

Body Condition Scoring Guide

How to assess your dog's body condition:

  • Underweight: Ribs easily visible, no fat cover, obvious waist from above
  • Ideal: Ribs palpable with slight fat cover, visible waist, abdominal tuck
  • Overweight: Ribs difficult to feel, thick fat layer, no visible waist
  • Obese: Ribs not palpable under thick fat, broad back, distended abdomen

Adjustment Strategy: If your dog needs to lose weight, reduce calories by 10-20% and increase exercise. For weight gain, increase calories by 10-15% with high-quality protein.

Frequently Asked Questions about 狗糧食計算器

我家狗正在減肥,這個工具能幫我控制熱量嗎?

當然可以!只要你在「Body Condition」選項中選擇「Overweight (needs loss)」,系統就會自動把每日熱量調降 10–20%,並建議如何搭配運動來達到理想體重。這不是理論上的估算,而是實際可行的操作方案。

使用這個狗糧食計算器安全嗎?資料會不會被偷走?

完全放心!所有計算都在你自己的設備上執行,不需要登入帳號,也不會將任何資料傳送到伺服器。即使你輸入的是狗狗的詳細健康資料,也不會有任何風險。這就是為什麼我們稱之為「零上傳」的專業級工具。

它適用於所有品種的狗狗嗎?

幾乎都可以!無論是博美、拉布拉多、柴犬還是哈士奇,只要你知道牠的體重與生活型態,就可以使用這個工具。對於大型犬(如大丹犬)或特殊需求(如糖尿病狗),建議配合獸醫師意見微調,但基本計算邏輯是一樣的。

如果我不確定狗狗的活動程度怎麼辦?

沒關係!你可以先從「Moderate」開始試試看,然後觀察狗狗的體重變化。如果三個禮拜後體重穩定或輕微下降,表示目前的熱量設定正確;若有明顯增重,則可再降低 10% 重新計算。

這個工具有手機版嗎?可以在 iPhone 上用嗎?

有的!它是響應式設計,無論是在 Chrome、Safari、Edge 或其他主流瀏覽器,都能完美呈現。手機版操作更方便,隨時隨地都能查,再也不怕忘記餵食時間啦!
