What is the oldest breed of dog?

The oldest breed of dog is believed to be the Saluki. This breed has been documented in ancient Egyptian tombs dating back to 2100 BC, where they were mummified and buried alongside their owners. The Saluki is a sighthound and was originally bred for hunting in the deserts of the Middle East. They are known for their speed and agility and were prized possessions of the nomadic Bedouin people. The breed is also recognized for its loyalty and has been described as a gentle and affectionate companion. Today, the Saluki is still used for hunting and is also a popular show and companion dog.
