Dogs have not developed complex hand motor skills like humans, so they cannot move their hands like humans. Instead, dogs rely on their limbs to move and explore, as well as using their mouth, nose, and tongue to interact with their environment and obtain items such as food. A dog's forelimbs and hindlimbs are used for support and movement. The forelimbs are typically used to explore and sense the environment, including acquiring information through touch and smell. The hind limbs are used for walking and running, allowing dogs to move quickly and catch prey.
In short, dogs do not have hand movement skills like humans, but they have other unique physiological characteristics and behavioral patterns that make They are very successful in adapting to their environment and lifestyle.
