Answer:
[PHYSICAL ADAPTATION]
dogs have a very good sense of smell. In fact, a dog's sense of smell is about 1 million times more sensitive than that of humans! A strong sense of smell helps wild dogs find food, and it alerts them to territories claimed by other dogs. Dogs claim their home territory by marking it with their scent, and other dogs smell that and know there is another dog nearby.
Dogs also have eyes that are very sensitive to motion and light. This helps them hunt at night, and they are very good at detecting any kind of movement of prey (other animals they eat). They also have very good hearing, so even if they can't see the prey, dogs can usually tell what direction the prey is moving.
[BEHAVIORAL ADAPTATION]
Wild dogs live in packs, or groups of other dogs, and each pack has a clear leader. Packs hunt together, and this means that they can work together to kill bigger animals.
