Dog Food by Age
A dog's nutritional needs change significantly across life stages. Select your dog's age to find the right guide.
PUPPY
Puppy · 0–12 months3 stages
Rapid growth requires high protein, controlled calcium, and DHA. Feeding frequency and portion size vary by age in months.
The most critical transition from mother's milk to solid food. Low-digestive-burden wet or soft kibble is recommended.
Rapid bone and muscle development — calcium-to-phosphorus ratio and protein content are the top priorities.
Preparing to transition to adult food. Large breeds should continue puppy formula through this stage.
ADULT
Adult · 1–7 years3 stages
Balanced nutrition for weight maintenance and activity level. Calorie needs vary significantly by size.
Dogs under 10 kg benefit from calorie-dense food with small kibble sizes for easier digestion.
10–25 kg dogs need regular weight monitoring and calorie adjustment based on activity level.
Dogs over 25 kg require lifelong weight and calorie management to reduce joint strain.
SENIOR
Senior · 7+ years3 stages
Lower calories, joint support, and kidney-protective nutrition become priorities as dogs age.
Small seniors benefit from low-phosphorus, soft-texture food that supports dental and kidney health.
Medium seniors benefit from foods with added glucosamine and chondroitin for joint care.
Large seniors need low-calorie, high-quality protein food that supports joint, heart, and kidney function.
“Nutritional needs by age are averages — every dog is an individual. Combine the guidelines with regular vet check-ups.”
