Raising exceptional American Bullies begins long before puppies go to their new homes.
Every stage of puppy development plays a critical role in shaping future health, confidence, temperament, and adaptability. Breeders who understand these developmental periods can provide the experiences puppies need to become stable, well-adjusted adult dogs.
From birth through placement, every experience matters.
In this guide, we’ll explore the major American Bully puppy development stages and explain why each stage is essential for long-term success.

Stage 1: Neonatal Stage (Birth to 2 Weeks)

During this stage, puppies are completely dependent on their mother.
Characteristics of the Neonatal Stage
- Eyes remain closed.
- Ears remain closed.
- Puppies sleep most of the day.
- Nursing and warmth are critical.
- Rapid physical growth occurs.
Breeder Priorities
Responsible breeders should focus on:
Maintaining Proper Temperature
Newborn puppies cannot regulate body temperature.
Monitoring Weight Gain
Daily weight checks help identify potential concerns early.
Supporting Maternal Health
Healthy mothers provide better care for puppies.
Gentle Handling
Early positive handling can support neurological development.
Understanding proper neonatal care begins with mastering the whelping process.
