Mans, or man’s best friend, has been an important part of human life for thousands of years. First domesticated around 10,000 BC, the companionship and affection offered by dogs has made them one of the most loved and loyal animal companions known to mankind. From providing protection and security to providing comfort and companionship, dogs are renowned for their special ability to bond closely with humans and become an integral part of their lives. The unique relationship between a dog and the owner can be attributed to a number of factors. Primarily, it is thought to be driven by the psychological connection that is formed, which is possible due to the heightened senses of smell, sight, and hearing that dogs possess, making them incredibly loyal to their humans. Additionally, dogs are highly trainable and can be taught to follow commands, meaning they can help humans in activities ranging from simple everyday tasks such as going to the bathroom, to more complicated tasks like retrieving items and providing assistance to the blind. Finally, the empathy and affection that some dogs provide to those in need is almost unparalleled. Certified therapy dogs can often provide therapeutic benefits to those who suffer from physical and mental health issues, such as anxiety and PTSD. Studies have found that interacting with dogs can provide several physical and mental health benefits, including reducing stress and anxiety levels, lowering blood pressure and improving social immunity. Overall, mans have had a significant impact on human life and continue to do so today. From their loyalty, sensitivity and intelligence, to their ability to provide comfort and security, the special bond between dogs and humans continues to be a unique and remarkable one.
