7 Main Growth Stages:
1. Neonatal Period (Birth – 2 weeks): Newborn puppies with closed eyes/ears depend entirely on mother, spending time eating and sleeping.
2. Transitional Period (2-4 weeks): Eyes and ears open; puppies begin crawling and interacting with littermates.
3. Socialization Period (3-12/16 weeks): Critical phase for learning; puppies leave mother around 8-12 weeks and need exposure to people, environments, and sounds.
4. Juvenile Period (4-6 months): High energy stage with deciduous teeth falling out; requires toys and training.
5. Adolescence (6-18/24 months): Sexual maturity; can be challenging; consistent training essential.
6. Adulthood (1.5-7 years): Peak years with stable body and personality; maintain exercise and nutrition.
7. Senior Years (7+ years): Declining activity; requires gentler exercise and frequent health monitoring.
