⚠️ Factors That Affect Puppy Growth
Breed and Genetics
Your puppy’s breed plays a major role in determining final size. A large-breed puppy will grow differently compared to a small-breed dog.
Nutrition and Diet
A balanced diet is essential for healthy growth. Poor nutrition can affect your puppy’s development and final weight.
Activity Level
Active puppies tend to maintain a healthy weight, while low activity can lead to weight gain.
Health Conditions
Any underlying health issues can impact your puppy’s growth rate and overall development.

This is the fastest growth phase. Puppies gain weight quickly and need frequent feeding.
Growing Stage (3–6 months)
Growth becomes steady, and body structure starts developing.
Near Adult Stage (6+ months)
