"Man's best friend" is a common phrase used to describe domestic dogs, referring to their millennia-long history of close relations, loyalty, and companionship with humans. The first recorded use of a related phrase is by Frederick the Great of Prussia. There's a reason we call them man's best friend. We can learn so many things from a dog's behavior, personality, demeanor, resiliency, and most importantly, the willingness to provide their family members with unconditional love, loyalty, and companionship down to their very last breath.
