Dogs are more than just devoted best friends; they’re also diligent sidekicks. Working dogs help humans in a myriad of ways. Some help to guide the sensory impaired, or to calm individuals with autism, anxiety or depression. They also help to alert and assist individuals with seizures or heart conditions. Still other working dogs spend their days sniffing out clues in the hunt for missing persons, or locating illegal substances during police searches. This infographic created by Blue Buffalo illustrates all of the ways in which working dogs are an asset to their human handlers and to humanity in general.
