Puppy & Kitten Nutrition: Complete First Year Feeding Guide
🎯 Quick Reference
Puppies
- • 0-3 months: 4 meals/day
- • 3-6 months: 3 meals/day
- • 6-12 months: 2 meals/day
- • Transition to adult food: 12-18 months
Kittens
- • 0-3 months: 4 meals/day
- • 3-6 months: 3 meals/day
- • 6-12 months: 2 meals/day
- • Transition to adult food: 12 months
Proper nutrition during the first year is crucial for healthy growth, development, and lifelong wellness. Puppies and kittens have dramatically different nutritional needs than adults—requiring up to twice the calories per pound and specific nutrient ratios for bone development, brain growth, and immune system maturation.
🐕 Puppy Nutrition Fundamentals
Nutritional Requirements
🔬 Key Nutrients for Growing Puppies
Macronutrients
- • Protein: 22-32% (vs 18% adults)

⚠️ Critical: Large Breed Puppy Nutrition
Large breed puppies (adult weight >50 lbs) have special requirements to prevent developmental orthopedic diseases:
- • Controlled growth: Don't overfeed to maximize growth rate

🐱 Kitten Nutrition Fundamentals
Nutritional Requirements
🔬 Key Nutrients for Growing Kittens
Macronutrients
- • Protein: 30-45% (higher than puppies!)
- • Fat: 18-35%
- • Taurine: 0.1% dry/0.2% wet (essential)
- • Arginine: 1.0% minimum

Obligate Carnivores: Kittens require animal-based protein. They cannot synthesize taurine, arginine, or vitamin A from plant sources like dogs can.
Feeding Schedule by Age
📅 Kitten Feeding Timeline
0-4 Weeks: Mother's Milk/Kitten Formula
- • Primary nutrition: Mother's milk optimal
- • Orphaned kittens: Kitten formula every 2-3 hours

- • No cow's milk: Causes diarrhea (lactose intolerance)
4-8 Weeks: Weaning Period
- • Introduce solid food: Wet kitten food + water/formula
- • Gruel consistency: Start with very soft, gradually thicken
- • Feeding frequency: 4-6 times per day
- • Fully weaned: By 8 weeks old
8-12 Weeks: 4 Meals Per Day
- • Food type: Kitten formula only
- • Wet vs dry: Mix or offer both
- • Schedule: 7am, 12pm, 5pm, 9pm
- • Free-choice: Option for tiny, frequent eaters
3-6 Months: 3 Meals Per Day
- • Schedule: Morning, midday, evening
- • Portion control: Important if overweight
- • Rapid growth phase: Most weight gain occurs
6-12 Months: 2 Meals Per Day
- • Adult schedule: Morning and evening

Portion Size Guidelines
⚖️ Daily Feeding Amounts
Wet Food (3 oz cans, ~80 kcal/can)
- • 8 weeks (2 lbs): 2-3 cans/day
- • 12 weeks (3 lbs): 3-4 cans/day
- • 4 months (4-5 lbs): 4-5 cans/day
- • 6 months (5-7 lbs): 4-6 cans/day
- • 12 months (8-10 lbs): 3-4 cans/day
Dry Food (~400 kcal/cup)
- • 8 weeks (2 lbs): 1/3-1/2 cup/day
- • 12 weeks (3 lbs): 1/2-2/3 cup/day
- • 4 months (4-5 lbs): 2/3-1 cup/day
- • 6 months (5-7 lbs): 3/4-1 cup/day
- • 12 months (8-10 lbs): 1/2-3/4 cup/day
Mixed Feeding: If combining wet and dry, reduce each proportionally. Example: 2 cans wet + 1/3 cup dry = 240 kcal wet + 130 kcal dry = 370 kcal total.
🥘 Choosing the Right Food
✅ What to Look For
AAFCO Statement (Required)
- • "Complete and balanced for growth"
- • "For all life stages" (acceptable)
- • Large breed puppies: Must say "including growth of large breed dogs"
- • Feeding trials: Better than formulated to meet
Quality Indicators
- • Named meat as first ingredient
- • Multiple protein sources
- • DHA from fish oil or eggs
- • No artificial colors/flavors
- • Established brand with research
🚫 Foods to Avoid
Never Feed
- • Adult or "all ages" dog food (to kittens)
- • Puppy food (to kittens) - insufficient taurine
- • Raw meat diets (infection risk for young)
- • Homemade diets (rarely balanced)
- • Grain-free (linked to DCM in dogs)
Toxic Foods
- • Chocolate, caffeine
- • Grapes, raisins
- • Onions, garlic
- • Xylitol (artificial sweetener)
- • Macadamia nuts, avocado
🔄 Transitioning to Adult Food

⚠️ Common Feeding Mistakes
🚨 Avoid These Errors
- 1. Overfeeding for "maximum growth"
Leads to obesity and orthopedic problems, especially in large breeds. Growth should be steady, not rapid.
- 2. Feeding adult food too early
Puppies/kittens need higher calories and specific nutrient ratios. Premature switch causes nutritional deficiencies.
- 3. Free-feeding large breed puppies
Unlimited access leads to too-fast growth. Measured meals are essential.
- 4. Supplementing balanced food
Adding calcium, vitamins, or other supplements can cause dangerous imbalances. Only supplement if vet-recommended.
- 5. Switching foods frequently
Causes digestive upset. Find a quality food and stick with it.
- 6. Using feeding charts as absolute rules
Charts are starting points. Adjust based on body condition, not just weight.
📊 Monitoring Growth & Body Condition
🎯 Ideal Body Condition
Visual Assessment
- • Visible waist behind ribs
- • Abdominal tuck (side view)
- • Not bony, not round
- • "Hourglass" figure from above
Touch Assessment
- • Ribs easily felt with light pressure
- • Thin layer of fat covering ribs
- • Spine not prominent
- • Shoulder blades move freely
Weight Tracking
- • Weigh weekly first 3 months
- • Weigh biweekly 3-6 months
- • Weigh monthly 6+ months
- • Use same scale, same time
💡 Veterinary Nutritionist Tip
"The biggest mistake I see is treating puppy and kitten food as 'optional upgrades.' These formulas aren't marketing—they're medically necessary. The difference in protein, fat, calcium, and other nutrients directly impacts bone development, brain growth, and immune function. One year of proper nutrition sets the foundation for 15+ years of health. It's the best investment you'll make in your pet."
— Dr. Jennifer Martinez, DVM, DACVN, Board-Certified Veterinary Nutritionist
