What muscles are used when a dog jumps?

When a dog jumps, several muscle groups are engaged, primarily the hind leg muscles, including the quadriceps, hamstrings, and gluteals. The core muscles also play a crucial role in stabilizing the body during the jump. Additionally, the forelimbs contribute to propulsion and balance, involving muscles in the shoulders and forelimbs. Overall, it's a coordinated effort across multiple muscle groups to achieve the jump.
