A new journal article by 91��ý PhD student Dayton Martindale argues that animal rights isn’t just about an absence of suffering—it’s about giving them agency

As a second grader,��Dayton Martindale was pretty sure he knew what his career path would look like: He was going to be the host of a show on Animal Planet. It made sense, given how much he enjoyed being around animals and learning about them.��

Around that time Martindale also started to understand that humans are mammals, just like many of the animals he loved. “I think that just stuck with me,” he says. “It affected how I looked at animals and saw them as more like myself.”

That was the beginning of a lifetime of philosophical and moral explorations of animal rights, culminating in his current PhD work in��environmental studies at the University of Colorado Boulder. And he’s been especially prolific this year: He’s had�� published since late 2025, all centered around two themes: How do we view animals as agents who desire their freedom, and how do we treat animal welfare as an object of public and political concern?��

One article, which was published in March 2026 in the��, pushes past the common thought that animal welfare simply means ending the most egregious animal abuses, giving farm animals more space to roam or taking captive animals out of small zoo enclosures—to the point of actually giving animals agency.��

“This paper was meant to be a sort of stepping-stone,” says Martindale. “It’s building toward what I want to do for my dissertation, which is to reach conservation practitioners and policymakers and advocates, and to think about how non-human animals’ interests and agency can be listened to in decision-making spaces.”��

The argument for agency��

Martindale’s article, “Liberty, Equality, Animality: On Freedom and Nonhuman Agency,” was first drafted in his Conceptual Foundations of Environmental Studies class (taught by his advisor��Ben Hale).��

The argument confronts the question of whether animals care about having free will over their own lives. “In a lot of animal ethics conversations, there's a big focus on reducing animal suffering, without a positive vision of what a good life for animals actually looks like,” says Martindale. “Both in philosophy and in animal behavior and science, there is a lot of evidence that animals have interests in exercising agency and making choices.”

One of the most common examples of this, Martindale says, is something called “contrafreeloading.” The concept is that many animals prefer to work for food rather than get it freely, and that they like to be actively engaged in their surroundings.��

Contrafreeloading has been studied in a wide range of species—from dogs to chickens to human children—showing that they will often ignore a free bowl of food and instead choose to complete a task to get that food, Martindale says. “Scientists interpret this as there being some reward in doing the task itself.”��

Martindale cites another study, in which�� when they were confined to an exhibit area or given the choice to move between the exhibit or a private enclosure. “When the pandas had more freedom to move—even if they mostly stayed in the exhibit—just knowing they could move around reduced their stress levels,” Martindale says.

Experiments in other species show that other controls, like being able to change the lights in their enclosure, or to choose the order in which they completed a task, also seemed to make them calmer and happier, he says.��

“I think there are limits on what can be accomplished in a zoo, especially for larger species,” says Martindale. “But what’s interesting about the framework in this paper is that it can provide a long-term aspiration—of no enclosures, or no cages at all—but it also can guide shorter term, small actions, whether in a zoo or in my house.” 


One way Martindale puts it into action in his own home is by delivering food to his shelter mutt, Geo, in a puzzle feeder, which requires him to work for his meals. Martindale also often lets Geo choose their route on a walk or takes him to parks and open spaces where he can be off leash.��

“What’s interesting is he's way better behaved off leash than on,” says Martindale. “On leash he’s always pulling. But off leash he can go sniff where he wants, but he'll also turn around whenever I call his name in a way that he doesn’t when he’s on a leash.” It’s almost as if Geo is reciprocating the respect Martindale is showing him by giving him his freedom.��

A shift in the movement��

The themes of the article parallel what Martindale describes as a “political turn” in the animal rights discussion in the last 15 years. Activists are now exploring how to establish institutions and infrastructure that can give animals, including wildlife and domestic pets, more agency.

“Traditionally, a lot of animal ethics was saying, ‘here's why you shouldn't eat meat, and why we shouldn't test on animals, and here's why we shouldn't have zoos,’” Martindale says, adding that 50 years of telling people to be vegan has had somewhat limited success. “The political turn is saying: That's all great, but what are the institutions that societies need to either achieve these goals or represent animals in some way?”��

Martindale cites Boulder’s Voice and Sight Program, as well as its off-leash dog parks, as a good example of how we can institutionally support animal agency. Another instance, he says, is the New York City Mayor’s Office of Animal Welfare, which administers programs that encourage co-habitation with wildlife or promote humane solutions for reducing community cat populations.��

He hopes that his writing, both academic and non-academic, might reach policymakers who plan urban spaces for dogs, relax leash laws or even install wildlife crossings over busy highways.��

Putting action into practice

Currently in the third year of his PhD studies, Dayton recently defended his prospectus, which will cover ethical and political relationships with wild animals.��

Prior to his PhD work, Martindale spent years working as a journalist and writer, exploring the intersection of animal rights, politics and the environment. Post doctorate, he’s hoping he can continue writing in the area of policy or advocacy work. “I love all this research, but I want it to feel connected to, informed by and relevant to social change.”��

“I think animals are really interesting, intellectually, philosophically and scientifically. But that's not why I'm in this. It’s because trillions of them are tortured and killed every year. And because humans are animals too, and our own well-being on this planet is tied up in sharing it well.”��
