Regular dog exercise is essential for maintaining a pet's physical health and mental well-being. Activities like walking, running, and playing fetch help to keep a dog fit, reducing the risk of obesity and related health issues. Exercise also promotes healthy joints and muscles, ensuring that a dog remains active and agile throughout its life. In addition to physical benefits, dog exercise provides mental stimulation. Engaging in play or training sessions can help prevent boredom and destructive behaviors. Socializing with other dogs during walks or at parks can also enhance a dog's social skills and overall happiness.
