Indian pariah dog
Archaeological findings indicate that this dog was in existence some 4500 years ago. Excavations in the Mohenjo-Daro site found in the Sindh region of Pakistan (Indus Valley civilisation) revealed an Indian Pariah dog skull dating to 2500 BCE. Also, there are various cave paintings across the Indian subcontinent that hints at pariah dogs to be one of the oldest dog breeds in the world.
