Here's why:
* Growth Hormone: During sleep, dogs release growth hormone, which is essential for bone growth, muscle development, and tissue repair. This hormone is most active during deep sleep stages.
* Rest and Recovery: Sleep allows the body to rest and recover from the day's activities. This helps with muscle repair, energy restoration, and overall growth processes.
* Brain Development: Sleep is crucial for brain development and cognitive function, which indirectly contributes to growth and development.
So, while dogs don't physically grow while they sleep, their sleep is essential for the body's processes that lead to growth.
