2. **Identifying Life Stages**:
- **Juvenile Phase**: This is the initial phase where the organism is not capable of reproduction.
- **Reproductive Phase**: This phase begins when the organism reaches reproductive maturity and can reproduce.
- **Aging Phase**: After the reproductive phase, the organism enters the aging phase where bodily functions begin to decline.

3. **Researching Dog Lifespan**:
- The average lifespan of a dog is typically around 10 to 13 years.
