Understanding Dog Aging
- Puppy Stage (0-1 years): Rapid growth and development
- Young Adult (1-3 years): Physical maturity and energy peak
- Adult (3-7 years): Prime years with stable health
- Senior (7+ years): Slowing down, increased health monitoring needed
- Small dogs typically live longer and age more slowly
- Large dogs age faster and have shorter lifespans
- Mixed breeds often have hybrid vigor and longer lifespans
- Health status significantly impacts aging rate
