Puppy Growth Stages

Feeding your puppy the right food is important for healthy growth. Puppies need different nutrition at each growth stage.

Knowing when to switch from puppy food to adult food helps your dog stay strong and active.

Key Development Phases

Puppies grow fast during their first year. Their bodies change a lot in this time. This affects what they need to eat.

There are three main phases: neonatal, transitional, and juvenile. Each phase has different needs.

• Neonatal (0-2 weeks):Puppies rely on mother’s milk for all nutrients.
• Transitional (2-4 weeks):Puppies start to open eyes and ears and try soft food.
• Juvenile (4 weeks to 12 months):Puppies grow rapidly and need high-energy, balanced food.

Nutritional Needs By Age

Puppies need food with more protein and fat than adult dogs. This supports their fast growth and energy.

Most puppies switch to adult food between 9 to 12 months, depending on their breed and size.

Age	Food Type	Nutritional Focus
0-8 weeks	Mother’s milk / Puppy milk replacer	High fat and protein for growth
8 weeks – 9 months	Puppy food	Supports bone, muscle, and brain development
9-12 months	Transition to adult food	Balanced nutrition for maintenance
12 months and older	Adult dog food	Maintain healthy weight and energy
