What are some behavioral and structural adaptations of dogs?

Dogs exhibit various behavioral adaptations, such as pack mentality and social communication, which help them thrive in human environments. Structurally, they have evolved traits like acute hearing and a keen sense of smell, allowing them to detect scents and sounds beyond human capabilities. Their body structure, including variations in size, coat type, and jaw strength, has also adapted to different roles, from hunting to companionship. Together, these adaptations enhance their ability to interact with humans and perform various tasks.
