Part 3: “Our Purpose”

Part 3, Chapter 23 Summary: “This Dog Will Change What You Think of Your Life”

Friedman reflects more on how dogs have saved his life. He recalls when he first moved to New York at 25 and was working at a marketing agency. The work wasn’t fulfilling, and Friedman struggled to keep up with deadlines. He soon realized this wasn’t what he wanted to do. He considered quitting, but was laid off not long later. Losing his job felt like a saving grace because it pushed Friedman to follow his dreams. He spent some time traveling, bringing his Nikon along with him. The photos he took of dogs in his travels gave him the idea for The Dogist. He launched the account on several social media platforms, and his new career began. This new online identity felt authentic and freeing to Friedman. He was finally doing something he loved. For a long time, he’d worried about disappointing his family, as he came from a long line of doctors who’d hoped he’d pursue medicine, too. He’d discovered his preference for the arts over medicine in college, but it’d taken him a few years to turn this passion into a realized dream: The Dogist.


Since starting The Dogist, dogs have given Friedman a purpose. The Dogist has also helped him help his brother Henry. In 2018, Henry was working an unfulfilling job in ad sales. Friedman encouraged him to start his own version of The Dogist, insisting that blogs and social media could transform his passions into “an actual career” (205). Henry tried filming jazz performers and posting about them online, but this avenue didn’t play out as Henry expected. Still eager to help Henry, Friedman suggested he join him on a cross-country road trip he was doing for The Dogist. Henry had recently acquired a van, and Friedman was working with The Sato Project, driving a foster dog named Finn around the country. Henry joined, and the trip proved transformative. Henry and Finn became immediate online celebrities. Friedman urged Henry to make a career of this, and Henry quickly became a “dogfluencer.” He adopted Finn, and they’ve since been traveling the country and rehoming other rescue dogs. Finn saved Henry’s life.

Part 3, Chapter 24 Summary: “Dogs of War”

Friedman describes his work with Warrior Canine Connection, a Maryland organization that connects service dogs and veterans with PTSD. Friedman marveled at how the dogs helped these vets emotionally and mentally. He shares several stories, describing the particularities of these human—canine bonds. One vet named Tyler traveled the country speaking on the importance of therapy dogs for vets like him. These stories are inspirational to many, Friedman argues, as they’re good comeback stories.

Part 3, Chapter 25 Summary: “The Eyes Have It”

Friedman considers the malleability of his Dogist work. Each Dogist adventure brings him somewhere different and teaches him something new. When he’s in Morristown, New Jersey, he’s especially moved by his work with The Seeing Eye. This organization—which pairs service dogs with visually impaired or blind individuals—was founded in 1927 by Morris Frank. Frank was blind and believed in the possibility of using dogs as guides. His research and travels inspired the organization and have since changed countless lives. The same is true of a parallel organization called Guiding Eyes, which was founded in 1954 in New York. This organization focuses on pairing deaf-blind individuals with service dogs who respond to body language to guide their owners. During one visit to Guiding Eyes, Friedman got the opportunity to let a dog named Arby lead him while he was blindfolded. Friedman was nervous at first, but soon relaxed and let Arby be his eyes. Arby safely led him down a busy city street, which awed Friedman.


Friedman also shares Anastasia Pagonis’s story by way of example. A sports enthusiast, Anastasia started to lose her sight when she was 11. She soon found safety in the pool. Her dog, Radar, helped her with her intensive training. She went on to swim competitively and even to compete in the Olympics. She told Friedman that Radar had changed her life and helped her accomplish these dreams.

Part 3, Chapter 26 Summary: “The Purpose-Driven Dog Life”

Friedman continues his reflections on the purpose of dogs. While they’re often meant to bring humans joy, dogs can also be trained in various skills. Such skills include guarding, racing, and even biting. One time, Friedman visited The American Kennel Club’s Working Group. These dogs are police dogs trained to attack and bite. Friedman actively participated in the training of one dog and was amazed by the dog’s fearlessness, strength, and tenacity.


Other dogs, Friedman explains, are skilled hunters. One time, Friedman connected with a man named David from Woods Hole, who invited him on a hunting trip. David’s dogs were especially skilled at retrieving the quails that the men had killed.


Other dogs are skilled at retrieving or saving humans. One dog named Oakley, owned by George Abraham, was known for her ability to rescue people from drowning. Sadly, Oakley died not long after Friedman met her, but Friedman believes that her short life had purpose.

Part 3, Chapter 27 Summary: “The Job Is Love”

Friedman argues that for some dogs, their only purpose is to love people. The late and former president George H. Bush’s dog Maggie was this way. After his death, Maggie was sent to a facility where she became a “professional hug dog” (238). Her only purpose was to let people hug her and feel love from her.


Friedman says that his dog Elsa is this way, too. He describes his and Sam’s daily routines with Elsa. She shows them love by sharing her life with them. He and Sam also bond over their shared love for Elsa. Every night, she joins them in their bed, and they spend time petting and hugging her.


This seems to have been the case for Rich Moore and his dog Finney, too. Friedman heard their story not long ago. In 2023, Moore and Finney disappeared from their Colorado home one day. Moore’s family and friends searched for them everywhere. Months later, Moore’s body was found in the mountains. However, Finney was still alive, lying loyally beside Moore’s remains. He didn’t want to leave Moore behind, which Friedman says was a sign of his loyalty. He argues that loving people is one of the most beautiful purposes a creature can have.

Part 3, Chapter 28 Summary: “The Future of Dogism”

Friedman reflects on the future of The Dogist. He considers a recent experience he had with a girl named Zoey Henry. Zoey was diagnosed with brain cancer after she started falling over and having seizures. After her diagnosis, she worked with the Make-A-Wish foundation and connected with Friedman: her wish was to take photos of dogs in need of better homes. Friedman brought her to Washington Square Park and Tompkins Square Park in New York City, where she helped him photograph dogs for his Instagram. Friedman marveled at how easily she connected with people and their dogs, and how happy she seemed. She also took some beautiful pictures. This experience made Friedman realize how purposeful his work can be.


In closing, Friedman returns to the story of his friend Angus and his dog Opal. Friedman caught up with Angus a few weeks after he adopted Opal. He was eager to see if Opal had changed Angus’s life the way he’d predicted. As soon as Friedman saw them together, he knew he was right. That’s where he got the title inspiration for his book.

Part 3 Analysis

The final section of the text explores the possibilities of Self-Discovery Through Animal Companionship. Throughout This Dog Will Change Your Life, Friedman highlights the many ways that dogs can rescue, redeem, heal, and connect people. In his third and final section, he underscores the ways that dogs might help the individual to find meaning and purpose, ushering them along their self-discovery journey and leading them to a more realized existence. He provides a series of anecdotes about dogs leading people to new jobs, dogs helping people to feel safer and more confident emotionally, dogs acquiring fighting and hunting skills, dogs offering people physical guidance, dogs offering people comfort, dogs saving people's lives, and dogs offering people hope. In all these ways, Friedman argues, dogs can validate a person’s sense of self. Some dogs facilitate vocational passions, while other dogs help people to remember the purpose, beauty, and wonder of being alive.


Friedman views his and his brothers’ dog-related careers as empirical proof that animal companionship can facilitate self-discovery. In Friedman’s personal experience, dogs have always been a central facet of how he’s understood himself. As a child, he learned how to communicate and relate to others via his relationships with his dogs. As an adult, he rediscovered the importance of dogs to his sense of self when he came up with the idea for The Dogist. Stuck in an unfulfilling, dead-end job, Friedman lacked a sense of direction in his life until he was laid off. Losing his job challenged him to identify what gave him meaning and to pursue this passion ardently. What resulted was The Dogist: “A parody site [of The Sartorialist] that [would] be its own content, obviously, but more than that—a new identity for [Friedman]” (201). Friedman’s Instagram page wasn’t an idle pastime, but a concrete way for him to solidify his authentic sense of self and to translate his identity to the world. 


Once Friedman followed this innate passion, he found a fulfilling vocational path, an authentic sense of self, and a hopeful and meaningful future, underscoring the Transformative Power of Human-Canine Bonds. As Friedman writes, “Dogs not only changed [his] life but changed what [he] thought of as life” (204). Discovering his true passion gave him a new perspective on his past endeavors that pushed him to take action and change his life for the better: “The fact that I failed at being premed and failed at my marketing job and survived gave me the courage to take a bigger risk.” To underscore the importance of prioritizing one’s passion, Friedman quotes comedian and actor Jim Carrey’s 2014 commencement speech at the Maharishi University of Management: “You can fail at what you don’t want, so you might as well take a chance on doing what you love” (204). For Friedman, what he loved was dogs. 


As Friedman rebuilt his life around this love, he experienced the benefits of this approach, garnering the knowledge and confidence to encourage his brother along a similar path. Henry’s experience emphasizes the benefits of Building Community Around a Shared Love of Dogs. With Friedman’s help, Henry also rediscovered his love for dogs. His online-documented travels with Finn have since afforded Henry a way to connect more people with more dogs, while giving him a fulfilling sense of self, too. In these ways, Friedman implies, dogs can inspire people to be as authentic as they are. Dogs’ guileless natures help people to perceive the world more openly and embrace their authentic dreams.


Friedman argues that dogs help their owners build confidence, which equips them to connect with others. No matter who the individual is, Friedman argues, dogs can “help people to define and then refine their identities while deepening and strengthening their relationships” (208). Friedman’s allusions to police dogs, hunting dogs, emotional support dogs, seeing-eye dogs, and facility dogs further exemplify how dogs can transform people’s lives and give them the love they need to be themselves. By sharing a varied set of examples, Friedman indicates that dogs are malleable and diverse creatures. There are so many dog breeds with so many innate temperaments and trainable skills that he believes every kind of human can find a dog who fits their personality and needs. 


For Friedman, dogs possess an inherent ability to promote both physical and emotional health in their human counterparts—spheres Friedman represents as equally important. He credits dogs’ inherently loving and loyal natures as the catalyst for the emotional growth owners experience from the human-canine bond:  “Being unconditionally loving and supportive, being unabashedly affectionate, being entirely present in the moment,” Friedman asserts, “is a job as central to survival as searching and rescuing” (241). Because love, support, and affection are essential to human survival, dogs allow humans to survive. While not grounded in hard data or scientific fact, Friedman’s sweeping array of experiential evidence allows the text to close on this hopeful, heartwarming note. The text offers the reader as much comfort as Friedman believes any live dog companion can.
