The saying, “Love me, love my dog” implies that your dog is a problem—something negative in the whole package of You. Could anything be more ridiculous? While it’s easy to assume that our dogs make us more lovable and even more desirable (I mean, really, how could it be otherwise?), is there any evidence for this point of view?

The answer is yes! Multiple scientific studies—extensions of research into dogs’ many social effects—have concluded that dogs enhance human attractiveness. Scientists have known for some time that people are more attentive to and socially engaged with those accompanied by a dog than those who are not. We also know that bystanders are more helpful toward people with dogs. Other studies have extended our understanding of the canine influence on human social activity by investigating more personal, intimate types of behavior in the areas of courtship, dating and romance.

Pick-up Lines

In one study, having a dog with him enhanced a man’s success when he asked women out. In this experiment, the man asked 240 women for their phone number— 120 times while accompanied by a dog and 120 times without one. He followed the exact same script whether the dog was with him or not.

The difference the dog made in his success rate was astounding. When he gave his pitch without a dog, 11 out of 120 women (9.2 percent) were sufficiently charmed to give him their number. When he was with a dog, 34 out of 120 (28.3 percent) complied with his request. With a dog, his success rate was three times as high. Never mind a wingman— if you want to meet someone, you need a wing-dog!

Studies have shown that people’s helpfulness and social interactions are prompted most strongly by light-colored dogs and puppies. An adult black dog was part of this experiment; researchers speculated that if the man had asked women for their phone numbers while accompanied by a light-colored puppy, his success might have been even higher. (Guéguen and Ciccotti 2008)

Why do dogs (of any kind) increase our appeal? To most dog lovers, explaining how dogs can make someone more attractive is pretty straightforward: people are more attractive if they have dogs because they have dogs! Quite simple —also quite circular. As it happens, there are a number of other, more satisfactory explanations.

Many people report that those with dogs seem safer, friendlier and more approachable; by being a conversation starter, the dog may also ease social awkwardness.

Interacting with companion animals can result in changes in our oxytocin and other hormone levels, and that may affect the opinion others have of us as well. Those who feel a rush of oxytocin in the presence of a dog may transfer the warm, fuzzy feelings to the person with the dog. So, dogs may make people attractive by prompting emotions that are extended to them by association.

This may not be good for our ego, but it can still be good for our love life!

Does This Dog Make Me Look Cute?

Another study surveyed 1,210 people on Match.com who owned pets—both cats and dogs—to learn if and how pets influenced their views about potential dates. One of the main findings was that dogs had a greater positive impact on the perceived level of attractiveness than did cats. (Gray et al. 2015)

Interestingly enough, there was also a gender component. The study concluded that dogs make men attractive to women to a greater degree than they make women attractive to men. Women were more likely to find someone attractive because they had a dog, and were also more likely to find a photo of a dog in an online dating profile a turn-on. Not surprisingly, more men than women ’fessed up to using a pet to attract a potential date. (I know of no studies investigating how dogs affect attractiveness between members of the same sex, but it would be intriguing to see what patterns emerge once that area has been explored.)

Compelling biological forces suggest the reasons for this gender difference, and there’s a large body of work on the subject. The basic theory is that, because women must commit a large amount of energy and effort to produce offspring (pregnancy and often greater caretaking responsibilities for the children), they need to be more selective about who they choose as a mate. Men, biologically speaking, are capable of producing lots of offspring with a minimum of, um, effort, so they can afford to be less discerning in their choices.

Of course, there are many exceptions, and in today’s world, the division of child-care responsibilities is often more equitable than in the past, but our evolutionary heritage still influences our behavior. Women are often attracted to men who have something to offer to potential offspring.

Having a pet may be a plus for several reasons. The expense of a pet may be a variation on finding a man in an expensive car attractive. If it demonstrates wealth, it could be appealing, since a lot of evolutionary research suggests that females prefer males with substantial resources to devote to offspring. The social skills observed when a man interacts with his dog may also add to his allure. Just like men with resources to share, those capable of emotional commitment and those with strong parenting skills are more likely to contribute to the successful raising of children. Dogs can enhance perceptions of all of these qualities.

Although the effects of having a dog were different for the two groups, the majority of men and women surveyed said that finding out that a date had adopted a pet made that person seem more attractive. (Cat guardians were less likely to feel this way than dog guardians.) As everyone in this study was a pet guardian, the increased attractiveness of someone with a pet may simply reflect our natural inclination to like people with whom we have things in common.

The youngest people in the survey— those in their 20s—were more likely than members of any other age group to express an attraction to someone because of a pet. They were also more likely to judge a date based on that person’s reactions to their own pet than were members of other age groups. Perhaps being a pet guardian makes these younger men and women seem more grown-up, mature or responsible, which could be a plus for younger people.

Another explanation for this strong age effect is the growing trend toward considering dogs to be members of the family. An increasing number of people describe their dogs (and cats) this way, and it’s possible that dogs influence mate choice by revealing a person’s emphasis on family. Compared with older people, who may be new to the concept or may never have fully embraced it, the youngest people in this study may have always placed this level of importance on their pets.

As it happens, Bark readers of all ages seem to be more likely than the general population to consider dogs as family members. In reply to a blog post asking about this, two-thirds of the answers used words that implied familial relationships: dogs were their babies, or they were their dogs’ moms and dads.

Dad or Cad?

Another study warns women to be aware of how dogs influence their views. Men can be attractive because they seem romantic, caring and interested in long-term attachments; in other words, they would make good dads. Another type of man is more of a cad—dangerous, exciting and into chasing women. Women are often attracted to cads for short-term relationships and to dads as long-term partners, but dogs can interfere with that classification.

Women taking part in this study were provided with descriptions of both cadlike and dad-like men. They said that overall, they preferred to marry the dads, but many expressed an interest in shortterm affairs with the cads. These same characters were then described to women with only one detail changed—they were now all dog guardians. Dogs made both dads and cads more attractive, but the difference was greater for the cads. In fact, if cads had dogs, they were even more appealing than dads with dogs.

Dogs appear to supply cads with the perfect combination of traits; attractive, exciting cads seem to have had their bad qualities erased by having a dog. The potential for manipulation is obvious: a man exploiting the shortterm cad-like strategy can block negative perceptions of his style by having a dog. As the authors of the research study write, “Thus, a cad with a dog is especially attractive to women, as they may believe they are getting the best of both worlds.” (Tifferet et al. 2013)

It’s wonderful to know that dogs can make men, and, to a lesser extent, women, more attractive. Now, if only scientists could find evidence that dog hair has the same powerful effect!

The dogs of childhood are important beyond imagination. Kids describe them as their best friends and as their siblings. Many children view themselves as the primary recipient of their pets’ affections. Often, young people see little difference between the close connections they have with the human members of their family and those they share with the non-human ones. Because of most animals’ shorter lifespans, though, many kids must face the death of a dog, cat, or other pet. Their emotional response to the loss of a pet and what they say about the experience is the subject of the dissertation research and further study by Joshua J. Russell, PhD.

According to Russell’s research, children’s responses to the death of a pet are predictable in some ways. Kids had a much easier time dealing with the death of a pet if the animal reached an age where death was expected. Early deaths, especially unexpected ones, made it much harder for children to come to terms with the loss. Russell points out that kids have a strong sense of fairness related to whether their animals lives as long as they were “supposed to” or whether they died before that. Acceptance was easier for kids whose pets lived far into the normal lifespan for the species. Generally, kids understood that hamsters and fish don’t live very long, but many struggled to understand that our dogs, cats and rabbits will often die before we do. When a death happened because of an accident, it was especially difficult for kids to cope.

Many children who Russell interviewed felt that euthanasia was the right thing to do if a pet was suffering. Kids were split in their views about getting another pet after the death of another. Some felt that it was disloyal to the previous pets and their relationships with them. Others felt certain that they would feel better if they got a new pet and that the new relationship didn’t have anything to do with the old one.

It’s always difficult to deal with the grief of losing dogs, and it hurts my heart (a lot) to consider the pain that it causes children. It’s no fun to think about the way it feels for children to lose a pet because we can empathize all too well, no matter how old we are.

What do you remember about what is was like when a dog from your childhood died?

“Yes, that’s just how it is with my dog, too!”

“Everybody knew that before reading about it.”

“I figured I wasn’t the only one who felt that way about my dog.”

“Obviously.”

These are common responses to stories about the many research papers investigating the relationship between people and dogs. Most of us read the latest scientific findings with a great sense of happiness and validation. Our relationship with dogs is very much like our relationship with our children? Yep. Our dogs consider their guardians to be extra special and emotionally important? Whew, thought so. Our attachment to our dogs provides us with many benefits? Duh. Being a helicopter parent does not cause the damage to fur kids that it can to human kids? Yay!  Gazing into our dog’s eyes can enhance the feelings of true love between us? Awww.

It’s exciting that there has now been enough research into attachment between people and dogs and the bonds they have for one another to prompt a review paper to suggest where to go from here. The recently published “Measuring dog-owner relationships: Crossing boundaries between animal behaviour and human psychology ” summarizes what we know and discusses what should be studied next as well as how. That means we can all happily anticipate more revelations that will further confirm the many details about what we know: Humans and dogs are close in wonderful ways that benefit us both. In the introduction to the paper, the authors say, “In this review, we propose that the next step in anthrozoology [study of interactions between humans and other animals] research is to use all the potential information within attachment theory, to reveal whether or not different types of relationship styles exist among different dog-owner dyads and how they might be identified. Furthermore, we give suggestions for which factors may contribute to the development of different attachment styles in dogs, hence deserving more attention in future studies of the dog- human relationship.” What this means is that there is a wealth of information about relationships between humans and the styles of connection that people have with one another that can be used to inform future research on the ways that dogs and people forms bonds to one another.

Some suggestions that these authors have are to focus on both dogs and people simultaneously rather than just one side of the relationship. They also recommend investigating physiological as well as behavioral responses to situations (such as separation and reunions) that are often the focus of attachment studies. They encourage addressing both the attachment style of individual dogs and the caregiving style of individual people to help pairs avoid any conflicts that have plagued them in the past and to help them form the best, most positive relationships in the future.

What are you most interested in knowing about the science of your relationship with your dog?

Old dogs CAN learn new tricks, but the way that they learn may be different than when they were younger. So concludes a recent study called “Aging effects on discrimination learning, logical reasoning and memory in pet dogs”. The study was conducted on 95 pet Border Collies who ranged in age from 5 months to over 13 years old. Researchers purposely chose dogs of the same breed in order to minimize any differences in performance that were unrelated to age.

Starting out with a spoiler, older dogs did worse than younger dogs on one of the tests, they did better on a second test, and there was no effect of age in the third test.

For the first test, dogs were trained to associate four images on a touch screen with a positive experience—receiving a treat. So, if the dogs touched these images on the screen, they received a treat. Another four images were associated with a time out, meaning that touching any one of them resulted in no opportunities to touch images for a brief period of time. After being taught these associations, dogs were tested with a pair of images that always included one randomly selected “treat” image and one randomly selected “time out” image. Sessions consisted of 30 tests with a pair of images. Dogs were considered to have mastered this task when they chose the right image 20 out of 30 times for four out of five sessions in a row. There was a linear relationship between age and the number of sessions it took dogs to learn this task, meaning that younger dogs learned it faster than older dogs.

In the second test, dogs were again shown a pair of images on the touchscreen, but only one of those images was one that the dog had seen before. In each case, the familiar image was one that the dog had learned had a negative association because it led to a time out if touched. The dogs could therefore make an inference that the unfamiliar image was the correct choice and would lead to a treat if touched. (These trials were interspersed in sessions that included pairs of images just as in the first test in which both images were familiar to the dogs.) In this experiment, the older dogs were, the more likely they were to choose the correct image, meaning that older dogs were better at solving this puzzle than younger dogs.

The final test in this experiment looked at long-term memory. Dogs were tested at least 6 months after the other parts of the study were completed to determine how well they retained what they had learned. When presented with pairs of images just as they had been in test one, over 90 percent of the dogs performed better than chance level (at least 22 correct out of 32) and there was no effect of age on the success rate.

This study shows that there are differences in cognitive abilities between older and younger dogs, but not that dogs of certain ages have better abilities than dogs of other ages. The way that age affects performance depends on the specific task dogs are asked to do.
