Part 1: “Our Identity”

Introduction Summary

Elias Weiss Friedman tells the story of when his dog Oreo saved his life. When he was two years old, his grandmother was watching him play outside when he and Oreo disappeared. She searched everywhere, finally calling Friedman’s parents and the police. They eventually found him on the curb with Oreo by his side. Friedman identifies this as one of life’s miracles. Countless similar stories can be found online, reinforcing Friedman’s arguments.


Friedman started The Dogist in 2013 as a way to share his love of dogs with others. His book explores why humans have such strong bonds with canines and how these bonds change them. He argues dogs keep people from isolation, teach them about themselves, and help them make connections. The Dogist honors these aspects of human-canine bonds.


Friedman asserts that dogs’ ability to change humans “isn’t a theoretical concept” (xvii). He uses his friend Angus as an example. Angus lives with depression and anxiety. Noticing his friend was struggling, Friedman suggested Angus get a service or emotional support dog. He’d noticed how well Angus responded to his dog, Elsa. Angus was skeptical at first, but soon found a dog who was right for him. When Friedman heard the news, he told Angus the dog, Opal, would change his life.

Part 1, Chapter 1 Summary: “What Is a Dog?”

Friedman sets out to understand the origins of dogs, noting that the text isn’t an academic book, but delves into the history of dogs’ domestication. They began as wolves. Wolves would enter human encampments in search of food. While some wolves proved dangerous, others proved to be friendly, loyal companions. The more integrated they became into human society, the more they were domesticated. Their biology and characters changed. Sixteen of the original breeds still exist, but humans have created countless others. This history shows how dogs have evolved with and because of humans.

Part 1, Chapter 2 Summary: “Breeding Is Fundamental”

Friedman continues reflecting on dog breeding. Because there are now so many breeds, humans have created a classification system. Confirmation shows formally recognize these various breeds.


Friedman remembers his childhood attachment to the dog encyclopedia. He reflects on all the book taught him about various breeds, their appearances, and temperaments. Friedman notes that while some dogs have bad reputations, their behavior is a symptom of their anatomy and the original conditions in which they were raised.

Part 1, Chapter 3 Summary: “Doggelgangers”

Friedman argues that humans developed so many breeds because they wanted dog companions that “reflected their lives” (15). While some dogs are better for hiking, hunting, or working, dogs shouldn’t be limited to their utility. Friedman references several movies where dogs reflect their owners’ personalities and appearances, noting that he’s observed this phenomenon in real life at the UK Kennel Club’s show Scruffts, which honors dogs’ unique personalities.

Part 1, Chapter 4 Summary: “The Tail That Wags the Human”

Friedman recalls the time his friend Jeff asked for help getting a dog. Jeff is in his mid-30s, like Friedman, and lives alone. He thought a dog would be a good alternative to being in a relationship and having kids. Jeff was set on a Basset, despite Friedman’s insistence that Bassets require a lot of care. His new Basset, Gertrude, proved challenging for Jeff as a caretaker. However, Jeff didn’t complain about all his new responsibilities; she changed Jeff for the better. He’s seen this same phenomenon countless times via his Dogist work.

Part 1, Chapter 5 Summary: “Origin Stories”

Friedman recalls his trip to Puerto Rico to work with The Sato Project—an organization that rescues and rehomes satos, or stray dogs. He was especially taken by the dog Chrissy, whom they rescued from a beach where dogs are often abandoned. He realized what hard work this was and how important organizations like The Sato Project are.


The same is true of the North Valley Animal Disaster Group. They rescue and return dogs to their owners after natural disasters. Friedman teamed up with them after the 2018 Camp Fire in Paradise, California. Organizations like these are devoted to the care of dogs. This work is essential to preserving human—canine relationships.

Part 1, Chapter 6 Summary: “Gimme Shelters”

Friedman reflects on all the dogs he’s met doing Dogist work in New York. He muses on why some people choose some dogs, suggesting that it’s related to people’s specific identities and dogs’ unique personalities.


When Friedman started The Dogist, he didn’t have a dog. He’d left his childhood dogs at home in Pennsylvania and didn’t think he was ready for his own in New York. During the COVID-19 pandemic, he and his friend Jeff went to Cape Cod. Being around Gertrude intensified Friedman’s desire for a dog, so he decided to foster. He contacted a local shelter, and the founder set him up with a Husky named Elsa. Friedman fell in love and adopted her shortly thereafter.

Part 1, Chapter 7 Summary: “Too Many Dogs?”

Since adopting Elsa, Friedman has only become more convinced that dogs can change your life. At the same time, he admits that not all shelters and breeders are reputable, and it’s important to choose the right one.


Friedman also argues that some people online are too skeptical of others’ dog ownership. He describes some photos he’s posted on The Dogist and commenters’ negative responses to seeing dogs in muzzles or with choke collars. People have also responded poorly when he’s shared difficult aspects of a dog’s past life. Friedman doesn’t want to promote animal cruelty, but does want to honor the positive aspects of the dogs’ new lives and homes.

Part 1, Chapter 8 Summary: “To The Rescue”

Friedman recalls the time he worked with Whitney Fang of Hearts & Bones Rescue (HBR) in Dallas. They’re a nonprofit devoted to solving the overpopulation of dogs in the South. Friedman visited the rescue and helped Fang choose dogs to send to New York to be rehomed. He was emotional seeing the dogs in their kennels. However, all of the dogs sent to New York were adopted within days or weeks.

Part 1, Chapter 9 Summary: “Every Dog Tells a Story”

Friedman argues that, however you acquire your dog, the dog you choose says something about you. He recalls the time he photographed the dog Lunchbox for The Dogist. Lunchbox had health issues due to the abuse and neglect he suffered from his previous owners. However, his new owner loved him and told Friedman how relaxed Lunchbox was. This is just one story that proves how dogs’ past lives can be as complicated as humans’. Owners must be aware of their dogs’ pasts because human-canine relationships are reciprocal.


Friedman reflects on his friend Adam, who’s been scared of dogs since he was bitten as a child. Friedman told Adam he’d experienced a rare incident of aggression and urged him not to let this experience keep him from enjoying dogs now as an adult. He soon changed Adam’s mind; when Adam came to Cape Cod during the COVID-19 lockdown, he bonded with Gertrude and Elsa.


Friedman describes the evolution of The Dogist. At first, Friedman focused solely on the dogs, keeping his camera within what he calls the “Dog Zone” —the area on the ground where the dog is located. He didn’t want to distract from the dogs by including the owners, but soon realized the page was suffering from this omission. After all, The Dogist was meant to honor human—canine relationships. He soon started including footage of him talking to the owners or the owners interacting with their dogs.

Part 1, Chapter 10 Summary: “Working Hand In Paw”

Friedman reflects on his evolving love for dogs. He grew up with Oreo, Matilda, Maggie, and Ruby. He loved all of the dogs, but they each had different temperaments and quirks. He references Stanley Coren’s The Intelligence of Dogs and Vilmos Csányi’s If Dogs Could Talk as he reflects on dog intelligence and personality. Some sources describe these dynamics according to a dog’s biddability (or ability to obey commands), softness, persistence, bombproofness (or fearlessness), and galoopy-ness (or playfulness). Friedman asserts that some of these traits are trained into dogs, while others are distinct to their breeds.

Part 1, Chapter 11 Summary: “Emotional Rescue”

Friedman describes all the emotions a dog’s face can hold. Their emotionality can teach us love and authenticity. He reflects on his interaction with a dog named Cheeto by way of example. Cheeto was born blind, but was active, agile, and friendly. The dogs he interacted with seemed to like him, too—they didn’t judge Cheeto for being different.

Part 1, Chapter 12 Summary: “A Dog Is a Nicer Person”

Friedman considers different representations of dogs in religion and literature. He references Christian, Hindu, Buddhist, and Jewish beliefs, and alludes to dogs on television. These representations prove that dogs are important, no matter the interpretation.


Friedman shares an anecdote from his own recent experience by way of example. He was writing at a café when he saw a little boy interact with another customer’s dog. The child was thrilled by the dog, and the owner seemed happier because of it. This interaction proved that dogs can awaken humans to life’s joy and offer connection.

Introduction-Part 1 Analysis

The opening sections of This Dog Will Change Your Life establish Friedman’s intentions for the text. Dog-lover and founder of the popular Instagram page The Dogist, Friedman identifies his nonfiction title as a way to honor the Transformative Power of Human-Canine Bonds. Because the text is part memoir, Friedman relies on his personal relationships and experiences with dogs to fuel his arguments. He opens the introduction with a childhood anecdote about a time he was rescued by a dog. This anecdotal account establishes Friedman’s authorial tone and stance. He presents himself as an average American individual who wants to share his love for dogs with others. Placing his personal experience at the fore invites the reader into Friedman’s world, while humanizing him, too. He may be a popular household name because of his Instagram page, but he opens his personal life to the reader on the page to establish trust. In turn, these anecdotal aspects of the introduction equalize Friedman and the reader; the text is a way for them to share their common love for dogs and to delight in all the ways that dogs can change a person’s life.


To maintain this friendly and approachable authorial tone, Friedman intentionally avoids including hard academic or historical data. In the introduction, Friedman makes clear that This Dog Will Change Your Life is simply meant to explain and explore the “various versions of why” humans “love spending time with [their] dogs” (xv). This mission statement establishes a down-to-earth tone that conveys Friedman’s devotion to accessibility over factual accuracy. This stylistic effect is evident in Chapter 1, “What Is a Dog?,” where Friedman attempts to answer the question of where dogs came from and why humans keep them as pets today. In this section, Friedman continues his broad-strokes approach to history and academics to answer these big questions, writing: “


Remember, it wasn’t an easy time to be alive. Various species were competing for the same resources. At some point, these wolves began to interact with early humans. […] Humans had food, and wolves, like all animals, like food. […] Many wolves tried to approach encampments and score scraps of food, but the ones that approached while still behaving in wolflike ways were most likely driven off or killed. […] The wolves that got near or even into an encampment and got food were the ones that acted friendlier, even affectionate [and made] friends with humans (5).


This passage refers to a specific era in history, but Friedman omits temporarily or geographically locating his brief historical summary. He also avoids specificity by using words like “various,” “wolflike,” “many,” “some,” and “most likely,” which convey general concepts rather than specific facts. Instead of lecturing his reader, Friedman aims to tell them the story of the inception of human-canine relationships in an approachable way. Friedman’s tale possesses the same mood as his surrounding anecdotal accounts. The story is meant to offer the reader some insight into canine domestication, but it intentionally avoids intellectualizing this history. Friedman assumes this authorial stance at the risk of obscuring fact, but as a way to maintain his reader’s attention and to widen audience appeal. Friedman positions the text as a fun and entertaining homage to how dogs change people’s lives.


Friedman toggles between allusions to his dogs, his friends’ dogs, and dogs featured on The Dogist to convey the multitude of transformative effects dogs can have on different people. In the case of his friend Angus, for example, his new dog Opal helped him to cope with his “specific set of emotional and psychological issues” (xxiii). At the same time, Friedman believes Angus’s experience with Opal is universal. Friedman uses this anecdote to argue that dogs can impact all sorts of people in similarly significant ways. 


Friedman’s anecdotes involving Jeff and Adam, Elsa, Gertrude, Lunchbox, and Cheeto show dogs helping humans to heal and humans helping dogs to feel safe and loved. Including these stories is Friedman’s way of visually illustrating the “many different people with diverse stories” he’s met, all of “[whom] are forging forward in life with the help of their dogs, and myriad kinds of dogs that are in their lives for many different and important reasons” (xxiii). Friedman is careful to represent an array of different experiences on the page. He references specialty dogs, dog shelters, dog rescuers, dogs on television, and dogs in books. He mentions shy dogs, friendly dogs, and brave dogs. He also describes owners who simply want companions, and those who want emotional support. This array of anecdotes creates a rich array of empirical data. While this evidence isn’t grounded in hard science, it does narratively tell a story of human—dog affection and love.
