Chapter 1 Summary: “What Do Animals Need?”

The text attempts to answer the question, “What do animals need in order to be happy?” (1). Farms, zoos, and pet owners must all consider welfare standards in the course of caring for animals, and the author contends that merely addressing animals’ behavior does not allow humans to create positive conditions for them. Arguing that emotions drive behavior, Grandin asserts that the best way to ensure that an animal leads a happy, healthy life is to look at “the core emotional systems of the brain” (3). By way of example, she cites gerbils. In the wild, gerbils dig complex tunnel systems in which to burrow. In captivity, they often develop the habit of digging excessively in the corners of their enclosures; this is a stress behavior. Scientists provided one group of gerbils with soft sand in which to dig and another with pre-made burrow systems. The gerbils that were given sand still developed excessive digging behavior, while the group with ready-made burrows did not. The conclusion of the study was that gerbils are fearful animals that need safety, not the freedom to dig. Emotions, not behavior, were at the core of the gerbils’ problem.


Neuroscience has shown that animals, like humans, have core emotional systems in their brains. The first is “seeking,” which encompasses curiosity, the drive to achieve goals, “the positive emotions of wanting or looking forward to something” (6), and the desire to investigate the environment. Seeking drives humans to learn and succeed in their careers, just as it drives animals to hunt and stalk prey. 


The second system is rage. Scientists once believed that the capacity to feel rage arose from the experience of being held captive by a predator. Frustration and low-level anger are both part of the rage spectrum, and some animals feel rage just because they are in captivity. 


Fear is the third system. Both animals and humans feel fear when they are threatened. Although panic it likely evolved from the feeling of physical pain, it is also connected to social attachment, as both animals and humans feel panic when they are separated from their mothers. Care (i.e., a mother’s love) and play are also important to animals, although researchers are still working to determine the role that these factors play in animal welfare.


In order to be happy in captivity, animals need enrichment in both youth and adulthood. Animal caretakers must be mindful of the fact that animal behavior indicates an animal’s emotional state. Unhappy animals in captivity develop abnormal repetitive behaviors (ARBs) such as pacing, rocking, biting or chewing, and repetitive jumping. Any animals that exhibit these behaviors can understood to be in distress. The author contends that in addition to watching for ARBs, animal caretakers must refrain from stimulating rage, fear, or panic and instead encourage seeking and play-based behaviors. Although this can be achieved by implementing enhanced environments (e.g., providing rats with toys and games), it is also important to be attuned to the complex relationship between behavior and emotion. Addressing specific behavior without taking emotion into account (like providing gerbils with a place to dig) does not always improve animals’ lives. Throughout the text, the author will show the various ways that humans can help animals to be happy in captivity.

Chapter 2 Summary: “A Dog’s Life”

Grandin asserts that dogs are unique among animals because of their orientation toward humans. Dogs are genetic wolves who, through the process of domestication, evolved to be deeply attuned to human behavior and human emotions. Unlike other animals, dogs can be trained using the promise of human happiness alone. Cats require treats to be trained, but dogs will learn behaviors just because doing so makes their owner visibly happy.


Dogs evolved from wolves, but the author was surprised to learn that much of what humans thought they knew about wolves is inaccurate and has been based on flawed research that has since been debunked by the very scientists who first conducted it. It is not true that dogs, like wolves, live naturally in packs in which one dominant male controls access to the pack’s female. That model for dog and wolf behavior was developed based on observations of wolves in captivity, and even wolves behave differently in captivity than they do in the wild. In the wild, wolves live in small family groups. Typically, a mating pair raises pups together, but that unit also accepts other wolves if the need arises. For example, the sibling of the mating pair might be absorbed into their group if a mate dies. The study that gave rise to the alpha-male theory was developed using a group of unrelated captive wolves that developed a dominance structure to deal with a situation that was, for them, a very unnatural grouping.


Some individuals still argue that dogs are pack animals and therefore need their owner to be the pack leader. Cesar Milan, a celebrity dog trainer who lives in a compound with more than 30 rescue dogs, is chief among the supporters of this view. Grandin acknowledges that although dogs are not pack animals and do not need pack leaders, Milan’s dogs do function as a pack for the same reason that the captive wolves in the now-disproven wolf study did. She contends that just like the captive wolves, Milan’s dogs are unrelated animals with different backgrounds, and they have been forced to live together in one of the most unnatural social formations for modern dogs. As such, they need a rigid dominance hierarchy in order to keep the peace. However, this does not mean that all dogs need a pack leader or that humans should try to dominate their dogs.


Because of the domestication process, dogs ultimately came to resemble wolf puppies in their behavioral patterns, emotional response systems, and cognition. For this reason, thinking of domestic dogs like children might be a better model for dog owners than thinking of them as pack animals in need of dominance. Humans need to establish behavioral expectations, rules, and boundaries, but this is also true for human parents raising children. Grandin therefore concludes that domestic dogs do not need to be dominated; they need to be guided toward acceptable behaviors.


After researching dogs, wolves, and their history, the author has developed a set of best practices to help dog owners give their dogs happy lives. The ideal number of dogs for the average dog owner is either one or two. Solitary dogs do well with their humans, and dogs can also be happy in pairs. Beyond that, the dynamics become tricky. Some dog breeds, like huskies, have retained more typical wolf behaviors than other breeds. By contrast, spaniels, toy poodles, and other small dogs are the least “wolfy.” Although the trait dubbed “wolfiness” correlates positively with aggression, it also provides dogs with a genetic predisposition for problem-solving. Thus, huskies live together in groups relatively happily, while toy poodles struggle in groups larger than a dyad. Unless a human is particularly dog-savvy, the author recommends adopting only one or two dogs.


Dogs evolved to be free-roaming. During the author’s childhood, most people still allowed their dogs to have liberal access to the neighborhood. Now, however, social conventions and fears about safety have put leash laws into practice, and dog owners typically only allow their dogs unfettered outdoor access in fenced yards. The author worries that these changes have adversely impacted dogs’ well-being, leading to increased aggression.


Dogs are social and need the company of either a human or another dog. The author worries about dog owners who are out of the house all day long and only have one dog, as that dog will likely have its panic drive activated by separation anxiety. The author advises people who work outside of the home to either not adopt a dog or to adopt two dogs in order to keep the dog’s panic drive in check. The company of other dogs also helps with socialization. Dogs need to learn appropriate behaviors, both as juveniles (younger than one year) and then again during what most researchers label as a “teenage” phase between the ages of one and two. 


Puppies must be taught to manage frustration, otherwise they overdevelop their rage impulse. Positive reinforcement works better than punishment with dogs, and dogs naturally learn frustration-tolerance and impulse control through the “stay” and “wait” commands. Teaching a dog to remain in one spot until they are prompted to move helps them to self-calm and learn to tolerate delays in getting what they want.


Dogs can have both fear-based and dominance-based aggression, and it is helpful to understand the difference. Emotions drive action, and dogs who want to control their environments (e.g., stealing a toy from another dog) might display aggression. Other dogs respond to fear with aggression, snapping or biting when they feel threatened by a person or another dog. Dealing with these behaviors is easier if the owner abandons the idea of acting as the dominant pack leader. Dominance aggression can be managed when the underlying anxiety is dealt with; if a dog becomes aggressive when they believe that their food bowl will be taken away, feeding them in the same spot each day and rewarding non-aggressive behavior will help address the issue. Fear-based aggression (reactivity) can also be dealt with using positive reinforcement. If dogs are afraid of new people, Grandin recommends giving slow introductions and treats whenever they encounter a stranger. 


Dogs can also develop fears and anxieties that do not lead to aggression. Many dogs are afraid of inclement weather, loud noises like fireworks, or even other dogs. The author describes the use of anxiety-reducing wraps to help these dogs and notes that similar approaches are used to calm anxious cattle. After learning about the use of squeeze chutes to calm cattle, Grandin developed a squeeze machine to calm herself. As a person with autism, she often experiences anxiety, and she also feels a greater kinship with animals. Like animals, she often thinks visually rather than linguistically, and many tools developed to help animals are also useful to her. It does not surprise her to learn that squeeze-technology can be calming to dogs, and she urges owners with anxious dogs to try it.


It is important to remember that dogs are individuals. Additionally, while there are breed-specific traits, it is also possible to selectively breed for particular traits. Pit bulls are a result of this kind of breeding, and they now have a reputation for being violent dogs. They were originally bred to fight other dogs, not to attack humans, but unethical breeders crossed dogs showing dog-aggression with dogs showing aggression toward humans; the resulting offspring were hyper-aggressive and ruined the breed’s reputation.


Dogs’ seeking need must be met. While this can happen through games and access to a yard, walks are the best way to address a dog’s seeking need because this activity most resembles the free-roaming lifestyle that dogs are designed to have. Dogs also need social contact with either another dog or humans so that their panic system does not get activated. They should not be left alone all day. 


Dogs also need to play. Especially as juveniles, they should have a wide variety of toys that should be rotated in order to maintain the dogs’ mental stimulation. At minimum, dogs need an hour of attention from their owners each day, during which they are the sole focus of their owner’s attention. Play should be dog-directed. If a dog enjoys playing fetch or tug-of-war, the owner should engage in those activities for their play time.

Chapters 1-2 Analysis

In this section, Grandin introduces the concept of Using Core Emotional Systems to Improve Animal Welfare. The book’s primary purpose is to help animal owners, handlers, workers, and researchers alike to develop science-backed animal welfare standards that are based on an understanding of the relationship between animal emotions and behaviors. To this end, Grandin argues that all animals deserve “freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury, and disease, freedom to express normal behavior, and freedom from fear and distress” (1). She believes that people can provide animals with these opportunities, even in commercialized agricultural settings like poultry barns and slaughterhouses. In the past, behaviorism has played a dominant role in the way that humans understand animals, but Grandin argues that emotions drive behavior. Because there is a complex interplay between these two factors, it is essential to understand how animals process emotion. She therefore outlines four core emotional systems and several secondary systems that drive animal behavior, emphasizing that everyone from dog owners to cattle handlers can act upon a detailed understanding of these systems to guarantee their animals the happiest lives possible.


In Grandin’s discussion on seeking, she draws upon a multitude of common experiences with dogs in order to place her explanations in a real-world context—essentially using “pictures” to illustrate her meaning in a way that mirrors her own naturally visual thought processes. After framing seeking as a complex set of drives that compel an animal’s curiosity, exploration, stalking, and hunting, she emphasizes that seeking is a universal behavior. Just as it makes cats adept predators, it also makes humans goal-oriented. 


Grandin also notes that dogs evolved alongside semi-nomadic humans and that even when humans did create settlements, dogs were allowed to be free-roaming. Thus, even modern dogs have a strong seeking drive and would prefer to spend a large percentage of their day exploring their environment. Because fences and leashes are now standard, it is more difficult for owners to meet their dogs’ seeking needs. Grandin therefore urges owners to approach dog ownership with seeking in mind, providing opportunities for walks and play. With this advice, Grandin advocates for a research- and emotion-based model, and it is clear that her ultimate goal is to improve animal welfare standards by meeting animals’ authentic emotional needs.


With her discussion of rage as the third core emotional system, Grandin introduces The Tension between Animal Ethics and Productivity. Many scientists believe that animals’ rage is the result of deep, generational memories of being caught in the jaws of a predator. Grandin herself has dealt with manifestations of this emotional system in animals during her work with the commercial cattle, pig, and poultry industries, and her early mention of this issue promises a deeper explanation in the chapters dealing with cattle, pigs, and zoo animals. On a related note, her discussion of panic once again emphasizes the universality of this emotion that both animals and humans experience when separated from their mothers or young too soon in life, or when they are removed from their natural social groups. Because these systems are not widely known, Grandin wants to highlight their importance, and she argues that animal behaviors cannot be addressed without addressing the emotions that underlie them.


In Grandin’s second chapter, she provides an in-depth history and analysis of dogs and demonstrates how that history can help humans to better understand these animals. Much of her work concerns the practical application of scientific knowledge and observational data, and in a broad sense, this chapter follows that model. The history and information that she shares about dogs informs the practical pieces of advice she offers to dog owners. One of this chapter’s most important points involves Grandin’s explanation of the history about dog and wolf behavior, for she boldly debunks the common but misguided belief that dogs and wolves are “pack animals” led by one dominant “alpha male.” By tracing the origins of this widespread misconception, she indirectly demonstrates the rigor of her own scholarship even as she stresses that this misguided understanding of dogs and wolves came from a faulty study that its own researchers later abandoned. To further support her point, she cites more accurate research proving that wild wolves, unlike those forced to live in captivity, do not live in unrelated packs, but in small family groups. Because dogs are essentially genetic wolves, dog behavior mirrors wolf behavior, and dogs also do not typically need a “pack leader.” This chapter lays the groundwork for Grandin later argument that observations of wild animals are the key to understanding their true, innate behavioral patterns.


In terms of practical application, the understanding that dogs do not need a true alpha is implied to be the basis for how dog owners should treat their animals. Because dogs most likely view their owners as surrogate parents, Grandin argues that people should see themselves as parents rather than pack leaders, and her training advice follows this gentler model. Grandin’s broader argument is that dogs, like children, need firm but loving guidance. The model that Grandin provides is gaining popularity in the dog-training world and runs counter to training that is based on the now-debunked idea that humans must dominate dogs in order to elicit desirable behaviors.


Grandin also stresses the importance of using core emotional systems to improve animal welfare, applying this theme specifically to dog behavior to stress that fear can manifest as either fight or flight in dogs. Specifically, she notes the prevalence of fear-based aggression in dogs that have had traumatic experiences with either other dogs or humans. A dominance-based training model, which does not consider dogs’ needs or emotions, would advocate for using negative reinforcement to curb aggression, but Grandin argues that the core emotion at the root of aggression—fear—must first be directly addressed. If a dog is aggressive around food because it is fearful that its food will be taken, the dog should be fed alone and rewarded when it does not demonstrate aggression. Because Grandin’s model is backed by research and based on core emotional systems, it is designed to address dogs’ innate behavioral patterns and emotional responses to their environment.


Autism as a Framework for Understanding Animals also emerges as a key theme in this chapter. Grandin is known for countering common misconceptions about autism and reframing the neurotype as a positive attribute in order to challenge the traditional medical model, and her perspective also informs her work with animals. In this chapter, she discusses the use of pressure to calm anxiety in dogs, linking this technique to coping mechanisms that are also effective for people with autism. For example, the squeeze machine that she discusses here is one of her most famous innovations, and it represents her ability to understand animals and people with autism in a way that neurotypical individuals cannot. 


Grandin feels a special kinship with animals and notes that her own core emotional systems work similarly to those of many animals. Because she experiences fear-based anxiety, she finds that she benefits from the same anxiety-reducing measures that help animals, such as gentle pressure applied to her torso. Grandin’s observations on the fact that autism can inform animal welfare standards places her on the vanguard of a seismic shift in cultural attitudes toward neurodivergence. When she discusses her special relationship with animals, her descriptions anticipate a crucial paradigm shift in which there is greater acceptance for the myriad manifestations of neurodivergence.
