Dogs Are People, Too

If we granted dogs rights of personhood, they would be afforded additional protection against exploitation. Puppy mills, laboratory dogs and dog racing would be banned for violating the basic right of self-determination of a person.

11.1.13 - Dogs Are People, Too2

FOR the past two years, my colleagues and I have been training dogs to go in an M.R.I. scanner — completely awake and unrestrained. Our goal has been to determine how dogs’ brains work and, even more important, what they think of us humans.

Now, after training and scanning a dozen dogs, my one inescapable conclusion is this: dogs are people, too.

Because dogs can’t speak, scientists have relied on behavioral observations to infer what dogs are thinking. It is a tricky business. You can’t ask a dog why he does something. And you certainly can’t ask him how he feels. The prospect of ferreting out animal emotions scares many scientists. After all, animal research is big business. It has been easy to sidestep the difficult questions about animal sentience and emotions because they have been unanswerable.

Until now.

By looking directly at their brains and bypassing the constraints of behaviorism, M.R.I.s can tell us about dogs’ internal states. M.R.I.s are conducted in loud, confined spaces. People don’t like them, and you have to hold absolutely still during the procedure. Conventional veterinary practice says you have to anesthetize animals so they don’t move during a scan. But you can’t study brain function in an anesthetized animal. At least not anything interesting like perception or emotion.

From the beginning, we treated the dogs as persons. We had a consent form, which was modeled after a child’s consent form but signed by the dog’s owner. We emphasized that participation was voluntary, and that the dog had the right to quit the study. We used only positive training methods. No sedation. No restraints. If the dogs didn’t want to be in the M.R.I. scanner, they could leave. Same as any human volunteer.

My dog Callie was the first. Rescued from a shelter, Callie was a skinny black terrier mix, what is called a feist in the southern Appalachians, from where she came. True to her roots, she preferred hunting squirrels and rabbits in the backyard to curling up in my lap. She had a natural inquisitiveness, which probably landed her in the shelter in the first place, but also made training a breeze.

With the help of my friend Mark Spivak, a dog trainer, we started teaching Callie to go into an M.R.I. simulator that I built in my living room. She learned to walk up steps into a tube, place her head in a custom-fitted chin rest, and hold rock-still for periods of up to 30 seconds. Oh, and she had to learn to wear earmuffs to protect her sensitive hearing from the 95 decibels of noise the scanner makes.

After months of training and some trial-and-error at the real M.R.I. scanner, we were rewarded with the first maps of brain activity. For our first tests, we measured Callie’s brain response to two hand signals in the scanner. In later experiments, not yet published, we determined which parts of her brain distinguished the scents of familiar and unfamiliar dogs and humans.

Soon, the local dog community learned of our quest to determine what dogs are thinking. Within a year, we had assembled a team of a dozen dogs who were all “M.R.I.-certified.”

Although we are just beginning to answer basic questions about the canine brain, we cannot ignore the striking similarity between dogs and humans in both the structure and function of a key brain region: the caudate nucleus.

Rich in dopamine receptors, the caudate sits between the brainstem and the cortex. In humans, the caudate plays a key role in the anticipation of things we enjoy, like food, love and money. But can we flip this association around and infer what a person is thinking just by measuring caudate activity? Because of the overwhelming complexity of how different parts of the brain are connected to one another, it is not usually possible to pin a single cognitive function or emotion to a single brain region.

But the caudate may be an exception. Specific parts of the caudate stand out for their consistent activation to many things that humans enjoy. Caudate activation is so consistent that under the right circumstances, it can predict our preferences for food, music and even beauty.

In dogs, we found that activity in the caudate increased in response to hand signals indicating food. The caudate also activated to the smells of familiar humans. And in preliminary tests, it activated to the return of an owner who had momentarily stepped out of view. Do these findings prove that dogs love us? Not quite. But many of the same things that activate the human caudate, which are associated with positive emotions, also activate the dog caudate. Neuroscientists call this a functional homology, and it may be an indication of canine emotions.

The ability to experience positive emotions, like love and attachment, would mean that dogs have a level of sentience comparable to that of a human child. And this ability suggests a rethinking of how we treat dogs.

Neuroscientist Gregory Berns explains the “hot spots” on the MRI.

 

DOGS have long been considered property. Though the Animal Welfare Act of 1966 and state laws raised the bar for the treatment of animals, they solidified the view that animals are things — objects that can be disposed of as long as reasonable care is taken to minimize their suffering.

But now, by using the M.R.I. to push away the limitations of behaviorism, we can no longer hide from the evidence. Dogs, and probably many other animals (especially our closest primate relatives), seem to have emotions just like us. And this means we must reconsider their treatment as property.

One alternative is a sort of limited personhood for animals that show neurobiological evidence of positive emotions. Many rescue groups already use the label of “guardian” to describe human caregivers, binding the human to his ward with an implicit responsibility to care for her. Failure to act as a good guardian runs the risk of having the dog placed elsewhere. But there are no laws that cover animals as wards, so the patchwork of rescue groups that operate under a guardianship model have little legal foundation to protect the animals’ interest.

If we went a step further and granted dogs rights of personhood, they would be afforded additional protection against exploitation. Puppy mills, laboratory dogs and dog racing would be banned for violating the basic right of self-determination of a person.

I suspect that society is many years away from considering dogs as persons. However, recent rulings by the Supreme Court have included neuroscientific findings that open the door to such a possibility. In two cases, the court ruled that juvenile offenders could not be sentenced to life imprisonment without the possibility of parole. As part of the rulings, the court cited brain-imaging evidence that the human brain was not mature in adolescence. Although this case has nothing to do with dog sentience, the justices opened the door for neuroscience in the courtroom.

Perhaps someday we may see a case arguing for a dog’s rights based on brain-imaging findings.

  1. First step toward this would be a prosecutor using this study when asking for sentencing for an animal abuser….like say the Puppy Doe case? Get it in the books.

  2. It is no big secret to any dog lover/owner that dogs show emotion I can point out looks of joy, sadness, anger etc in each one of my dogs however I have a huge issue with test such as these.
    My issue: They are used the by fanatical animals rights groups to humanize our dogs and turn them into our “legal children” vs our property. When dogs are considered property our rights to property are protected by law ie…I can not just see anyone in a park with a choke chain and turn them in for abuse that would have an end result of someone “rescuing” them from the said person causing them to walk in and remove a dog…because now the dog has rights and the owner does not

    This recent study you shared has been scooped right up with AR extremist screaming “SEE YOU ARE HURTING THEIR FEELINGS SCIENCE SAYS SO”

    Now if it is believed by many this is the case…we all better get used to a steak free diet cause cows have feelings too…so does our bacon .

    I love my dogs, I love my children more. The two are not equal.
    I love my dogs…I love my husband more again the two are not equal. and so on…

    Do I believe dogs have emotion, yes I do 100% what they do not have is Cognitive Thinking cognitive skills contribute to academic and occupational success. Broadly categorized, these critical skills include:
    Attention
    Working Memory
    Processing Speed
    Long-Term Memory
    Visual Processing
    Auditory Processing
    Logic and Reasoning
    These skills are interdependent. Often they overlap in their work with other skills, as all the bits of information entering the mind are processed and acted upon.

    They are not Rational thinkers that create solutions to significant problems facing modern society demand a widespread qualitative improvement in thinking and understanding. .

    Dogs run off of imprint memory & flight or flight responses.
    This makes them animals to the fullest definition.
    I want to own my animals, I want you all to own your animals so you can keep them!

    1. Humans run off of imprint memory and they run off fight or flight responses, by your criteria we are animals, which we are we just happen to have opened God’s Nair bottle and lost all our fur on our bodies.

  3. Thank you Anonymous

    This study has actually been critiqued by true experts in the science field as being inaccurate. As much as we love our animals they are animals and believing they are human is feeding into the animal rights groups that do not want you to own animals at all.

    1. I agree with Anonymous here above : Dogs (or any other four legged for that matter!) are NOT Humans .

      They lack far too many all too common Human skills: Lying, cheating ,pretending, coersing, seducing, greed,self pity – you name it: the list goes on!….

      Dogs say they can relate to INNOCENT (human ) Children just as they relate to all Innocents regardless of speices.

      Besides who in their right mind thinks there’s something to be happy about in being ADULT/arted????? *o*

  4. Personally I know dogs come up with solutions to issues faced by them. One of my male dogs spent the entire night digging a trench just under the new pen I had spent two days building for him. I went outside the next morning and the posts which were in cement, were laying this way and that and the fence was still attached to the posts, but the entire pen was ruined because he dug down 18 inches. I had to build a deck and then put up a pen on that to keep him from digging. He knew what he had done, when ever he looked at where his pen had been he had a sh*teating grin on his face.
