In the perpetual debate over which makes a better pet — dog or cat — cats have been taking a drubbing lately.
It’s a silly argument to begin with: Why must we deem one species superior? What possible good does that serve? And it’s mostly a waste of time. Converting a dyed-in-the-wool dog lover to a staunch cat lover is about as likely as getting someone to switch from Donald to Hillary.
Yet, conflict seems to be something we humans require, or at least enjoy. And the endless argument does provide fodder for bloggers. And, every now and then, something interesting comes up.
In the past year, scientific and semi-scientific studies comparing dogs and cats have come down more squarely on the side of dogs — enough so that you’ve got to wonder if some cat-hater is behind it all.
One such study was conducted as part of a new BBC2 documentary called “Cats v. Dogs: Which is Better” — a silly concept for a TV show, though we admit some of what they bring to light is thought provoking.
Dr. Paul Zak, a California neuroscientist, compared how much oxytocin dogs produce compared to cats, and he concluded that dogs love humans more than cats do. Five times as much to be exact.
It has been well documented that bonding, petting and having eye contact with your dog produces increased levels of the oxytocin, also known as the love hormone, in both dog and human.
“It’s one of the chemical measures of love in mammals,” Zak said. “Humans produce the hormone in our brains when we care about someone. For example, when we see our spouse or child the levels in our bloodstream typically rise by 40-60 percent.”
The neuroscientist checked the oxytocin levels in both cats and dogs, taking saliva samples from 10 cats and 10 dogs on two occasions – 10 minutes before a playtime session with their owners and immediately after.
“I was really surprised to discover that dogs produced such high levels of oxytocin .. The dog level of 57.2 percent is a very powerful response. It shows these dogs really care about their owners,” he said.
Zak, also known as “Dr.Love,” believes upping our oxytocin (and hugging more) could change the world. He once took blood from an entire wedding party and a sampling of guests, to see how their oxytocin levels went up during the ceremony.
He also spent two years trying to get the Food and Drug Administration to approve his use of oxytocin inhalers on experimental subjects. (In the meantime, as reported in The Guardian, he used one on himself.)
Zak’s determination that canines love us more than felines do was just the latest bit of bad press for cats.
Another recent study, at Manhattanville College in New York, found canines provide humans with more benefits than cats.
The research suggested dog owners are more conscientious, less neurotic and more agreeable than cat owners. Dog owners scored higher in well-being than cat owners on all measures.
Last year, a study at the University of California, Berkeley, found, through web-based surveying, that cat owners were more anxious than cat owners.
If you still don’t believe cats have been getting some bad press, check out this headline on a story about a study of cats last year: “Study: Your cat might be trying to kill you.”
The story dealt with a study by researchers from the University of Edinburgh and the Bronx Zoo that compared the personality of the domestic cat with bigger, wilder members of the cat species.
The headline … well, it’s what happens when you try to condense a 40-page study into eight catchy words.
So if you find yourself reading/listening to/watching the latest account of which is better, cats or dogs — whether it’s labeled science or not — be at least a little wary.
And if it stresses you out, go pet your dog. Or cat.

The study goes a step beyond stating the obvious, though, looking at why that is, and why using a dog as date bait — unfair as it may be — works better for men than women.
Titled “The Roles of Pet Dogs and Cats in Human Courtship and Dating,” the study was published this month in the quarterly research journal Anthrozoos.
It surveyed random Match.com users in the United States who included pet information in their dating profiles. More than 1,200 individuals took part.
The study found women put far more stock in a potential mate’s associations with pets — and particularly dogs — than men did.
Women were more than twice as likely as men to say they were attracted to someone because he had a dog. They were also twice as likely to judge a date based on how he interacted with his dog.
Why? The researchers hypothesized that it’s probably based on evolutionary instincts. Women tend to seek a partner who they think will make a responsible parent, while men are more likely to look for … well, we all know what they are looking for.
“Put in terms of evolutionary and life-history theory, females allocate a higher proportion of their reproductive effort to parenting while males expend more energy on mating,” the researchers said.
In other words, a man with a dog is seen as a more nurturing and responsible member of his gender and therefore, the line of thinking goes, will make a better daddy.
While dogs may help draw women to a man, the reverse isn’t quite as true, the researchers found.
When women see a guy with a dog, they see a man who is responsible and wants to settle down, and they are charmed. When men see a woman with a dog, they too see a person who is responsible and wants to settle down, and they — or at least the less evolved among them — get scared. Or so the researchers’ theory goes.
As the study noted, men have caught on to the fact that a dog can improve their odds with the opposite sex. Twice as many men as women admitted they’ve used their dog to lure a potential date.
So who’s to know whether that guy in the park playing with his puppy is a nurturing soul, or simply a con man posing as a nurturing soul, using his dog in the same way he might use Axe for men?
Women. That’s who. And I wish them luck.

Ten years after a dog was first successfully cloned, scientists have managed to produce the world’s first litter of pups to be born through in vitro fertilization.
In July seven puppies were born through IVF at Cornell University — five beagles and two “bockers,” or beagle-cocker spaniel mixes.
The achievement was not revealed until this week with the release of the research study.
Seems like science would have happened the other way around — that a “test-tube” puppy would have premiered long before we entered the even more science fiction-like era of cloned dogs becoming available on the marketplace.
But, while IVF has been used for decades in other animals, including humans, scientists had never succeeded in using it to produce a newborn pup.
Previous attempts to use IVF in dogs had resulted in very low rates of fertilization, and no live births at all once IVF embryos were transferred to a host.
“Since the mid-1970s, people have been trying to do [IVF] in a dog and have been unsuccessful,” said co-author Alex Travis, associate professor of reproductive biology at the Baker Institute for Animal Health in Cornell’s College of Veterinary Medicine.
What made it so difficult were some of the same factors that proved challenging in cloning dogs — females only ovulate once or twice a year, and their eggs are not transparent, making it harder to see the structures inside of the egg.
The Cornell researchers, in a joint project with researchers from the Smithsonian Institution, found that by waiting an extra day for eggs to mature before extracting them, they met with more success.
Adding magnesium to the environment where the sperm and egg met also helped with fertilization, the team found, according to a Cornell press release.
The achievement was revealed this week in a study published online Dec. 9 in the journal Public Library of Science ONE.
The seven surviving puppies (out of 19 embryos) are genetically the offspring of two different fathers (a cocker spaniel and a beagle) and three different beagle mothers, carried by the same beagle surrogate.
Unlike cloning, which involves transferring an existing (or dead) dog’s DNA into a donor egg, IVF involves the creation of a new genome through fertilization. Each each animal has a unique set of DNA.
The researchers say the development will open the door for preserving endangered canid species using assisted reproduction techniques.
It could also enable researchers to eradicate heritable diseases in dogs and facilitate the study of genetic diseases in dogs and humans, they say.

Some researchers are suggesting that selfish mama dogs may have played a role in the early domestication of the species by keeping the good food to themselves, as opposed to sharing it with their pups.
As a result, the researchers theorize, pups and young dogs ventured out of the wild and into human communities where they didn’t have to compete as hard for food — at least not with their own mothers.
(Being a cartoonist at heart — albeit one who can’t draw — I am picturing a young pup, sneaking away from the home of his domineering mother with one of those sacks on a stick over his shoulder, muttering to himself, “That bitch. That bitch. That greedy bitch!”)
Sure, there may be some substance to this research, but it mostly makes me laugh.
The researchers conducted experiments with feral dogs in India, then theorized that ancestral dogs thousands of years ago must have behaved the same way.
First, they offered low-quality biscuits to mother dogs, and the mother dogs tended to share those with their pups, with no conflicts arising.
Then they brought out the good stuff. Protein-rich meat seemed to make the mother dogs forget their motherly ways, growling at their pups to keep them away, and even grabbing meat from the mouths of their puppies.
The authors, Anindita Bhadra and Manabi Paul of the Indian Institute of Science Education and Research, say ancestral dogs, once they reached 8 or 9 weeks old, became able to clearly distinguish between protein rich food sources and the un-nourishing filler their mothers were trying to pass off on them.
At that point, the researchers theorize, many young ancestral dogs would set out for farming communities where they had access to what humans threw away. There is evidence also that the earliest farmers fed these dogs, making life among humans even more appealing.
The theory, outlined in the journal Royal Society Open Science, could help to explain the origins of dog domestication and how some ancestral dogs so willingly elected to live with people instead of with their own kind, Discovery reports.
“Ancestral dogs” is kind of a safe term scientists use — just in case dogs didn’t evolve from wolves, but from some other species.
As for why ancestral dog moms turned so selfish when a good cut of meat became available, Bhadra said, “We feel that the mothers just tend to grab the best resources when available.”
Ancestral mother dogs are not available to respond to those charges, so I will speak for them:
“Hey, you think it’s easy giving birth to 14 kids at once, and then raising them? Alone?
“Yeah, where IS dad? Good question. Haven’t seen him since he knocked me up.
“So, yes, I get a little anxious, a little snippy. But I’ve got to feed the whole lot of them, and protect them. It’s not like I can walk into the Food Lion and get all I need. You have no idea how tired I am. And yes, I get hungry, too. If I am not nourished, how do you expect me to nourish all of them? Go research that, why don’t you?”

An Oregon State University scientist’s study, published yesterday, is drawing a lot of attention for concluding (as scientific studies often do) the obvious:
The longer dogs live with us, the more dependent they become on us, and, as a result, their problem solving and survival skills aren’t what they were back when they were wolves.
Not to sound stupid, but duh.
This, friends, is evolution. Just as our ancestors could once shred apart a mastodon leg without using an electric carving knife, the ancestors of dogs — i.e. wolves — did, and do, what they have to do to survive.
But to say dogs are “dumbing down” as a result of the cushy life we are affording them, well that’s just a little narrow-minded.
I prefer to think of it as their skills taking a new direction.
Do we say children are becoming more “stupid” because they can’t use a manual typewriter or blacksmith tools?
Of course the scientist and author of this study didn’t use the word “stupid” — only headline writers do that.
More “dim” is how the Smithsonian put it. “Stupid” and “lazy thinkers” is what the Daily Mail called them. “Poor problem solvers” was the phrase of choice for Discover magazine. “Rubbish at solving problems,” reported the International Business Times.
Kinda makes you think the dog world could use a public relations pro at least as adept as the one who garnered the author of this study so much press.
Up to now, canine cognition studies have mostly marveled at how dogs have learned to interact with humans — and cited that as proof of how incredibly smart they are.
This new study, and some earlier ones, however, are portraying how much dogs are relying on humans as an example of how we are “dumbing them down.”
Yes, dogs are growing ever more dependent on humans. Just as humans are growing ever more dependent on computers. Who does that make stupider? Or is “more stupid” the righter way of saying that?
The study at issue is by Monique A.R. Udell, an assistant professor of animal and rangeland sciences at Oregon State University. In it, she compared the problem solving skills of dogs and wolves.
Ten pet dogs and ten wolves were presented with a solvable puzzle. Sausage was placed inside a sealed plastic tub with a hard to open lid. Just one of the dogs was able to open the tub, while eight of the wolves were.
Dogs often gave up more quickly, and turned to their human masters for guidance, often with that cute head tilt they use to manipulate us. (It’s only fair after the thousands of years we’ve been manipulating them, starting with their domestication.)
The wolves, meanwhile, sought out no such help, and spent more time trying to get in the box. It should be noted they also spent more time trying to get into an impossible to open box.
How smart is that?
Udell believes depending on humans for help is not necessarily a cognitive asset. She calls the response a “conditioned inhibition of problem-solving behavior.”
Udell’s findings were published yesterday in the journal Biology Letters.
So, no, I don’t buy that a wolf being able to open a box, or spending more time on the task, is proof they are any smarter. They use their paws and claws and teeth, and perhaps some brute force — but they don’t take a second to consider other alternatives.
Dogs on the other hand, have an entire arsenal — from head tilt to sympathy-invoking whimper, from batting their big eyes at us to licking our hands as if to say, “If you love me, you will help me with this.” To me, that’s proof dogs are smarter.
After all, which is more easy to manipulate, a can of Spam or a human being?

Why do some dogs seem so obsessed with chasing their tails?
Researchers at Bristol University in the UK have entered the second phase of a study aimed at finding the answer.
Scientists from the two-year “Bristol Spinning Dog Project” will visit the homes of the 50 non-spinning dogs to collect urine samples and cheek swabs, and complete training tasks aimed at assessing the pet’s personality and ability to learn, The Independent reports.
In the first phase of the study, the researchers examined spinning dogs, delving into everything from their DNA to their environments to their personalities.
After examining dogs that chase their tails, the researchers will use the non-spinners to act as a control group.
Tail-chasing, while the topic of many a YouTube video, is likely something we shouldn’t be laughing about — out loud or otherwise — at least in those cases where the behavior is obsessive.
The researchers say reasons for the behavior aren’t fully understood — some spinning dogs may be merely seeking attention or expressing a desire to play, but spinning frequently or while alone could be a sign of frustration or a more serious disorder.
“There isn’t much information in the research literature about why dogs spin,” said Beth Loftus, one of the lead researchers. “We think this behavior develops because of personality and genetics, as well as the environment during a dog’s first 16 weeks and learning throughout life. But we don’t really know what it means for dogs’ welfare.”
“We hope to be able to identify dogs that are starting to spin and stop it from developing to the point where they are doing it almost to the complete exclusion of other, more normal types of behavior,” she added.
The research is being funded by the Dogs Trust charity.

One out of every six fast food customers pick up a little something for the dog at the drive-thru window, according to a study by a marketing research company.
“These visits translate to a staggering number of trips (over 1,000,000,000 annually) where the dog is the one ‘lovin’ it,’” concludes a recent study on dog ownership and fast food habits conducted by Relevation Research.
The study found just over one third of canine owners have visited fast food drive-thrus with their dog — and, of those, four-fifths claim to have ordered menu items specifically for their dogs.
McDonald’s is visited most often by dog owners, followed by Burger King and Wendy’s.
With dog ownership, and dog pampering, expected to continue to grow — especially among baby boomers and millenials — QSRs (or quick service restaurants) would be well advised to put healthy dog treats on the menu, it suggests.
“Because of disposable incomes and empty nester status, Baby Boomer owners could be strong candidates for QSR,” said Nan Martin of Relevation Research. “But the Baby Boomer also has an evolving focus on health. That means menu items specifically targeted for dogs or dog-friendly in terms of ingredients will resonate best.
“QSR and dog food/treat manufacturers should team up to design dog-safe offerings. Companies catering to the dog will win with owners who want to, guilt-free, feel like they’re spoiling the dog.”
