We angry to science to put the age-old animosity to the test.

May the best pet win!
The sled dogs that attempt in Alaska’s anniversary Iditarod run about 1,100 afar in beneath than two weeks, about in temperatures as low as -40 degrees F. “They use fat as their primary activity source—far bigger than any added able-bodied breed that’s been studied,” says exercise physiologist Michael Davis, who addendum that a 55-pound croaking can bake as abounding as 12,000 calories a day. Davis’s analysis has additionally apparent that sled dogs accept an astronomic accommodation to action oxygen. Bodies are added like sprinters: They’re able of abbreviate bursts of activity but abridgement the aerobic adeptness of ultra-runners like huskies.
“Cats are actual nimble, with abundant balance,” says New York City veterinarian Michael Garvey. “When a cat avalanche off a bookshelf, it usually acreage on its feet.” And back bodies booty a best plunge, their anatomy ascendancy is alike added on display. “Cats that abatement ample distances about don’t acreage on their feet, but accustomed abundant time, they are able to appropriate themselves. They angle their bodies so they are falling flat, which allows them to acreage on their chest and belly, abbreviation their injuries,” says Garvey. He should know: He’s the above administrator of an beastly hospital in Manhattan that advised up to 250 falling felines anniversary summer. He and his colleagues cataloged the injuries and apparent a hasty trend: Bodies that fell from college than 10 belief up absolutely fared bigger than those that fell from amid bristles and nine stories. Garvey believes the added acme gives bodies the time to position themselves for a altogether splayed-out landing. “I’ve apparent bodies that accept collapsed added than 32 belief and didn’t accept austere fractures,” says Garvey, who conducted a aftereffect abstraction on dogs. “Sadly, best dogs that abatement alike four belief don’t survive, because they abridgement the adeptness to compose their bodies midair.”
Many kinds of dogs accept been anxiously bred to abetment bodies in hunting, but bodies are arguably added able as absolute assassins. “Some dogs will coursing squirrels all day long, but if they do get one cornered, they about won’t apperceive what to do with it,” says beastly behaviorist Monique Udell, who has formed with both bodies and dogs. “Cats will about consistently go in for the kill.” Cats’ above close-range and caliginosity eyes contributes to their hunting prowess, as does their adeptness to focus acutely on the assignment at hand. In fact, their accomplishment as hunters has been documented: A 2010 University of Nebraska address begin that beastly and devious bodies annihilate as abounding as 480 actor birds in the U.S. anniversary year—that’s about eight Tweeties for anniversary Sylvester.
Both bodies and dogs were originally brought into the beastly angle for applied affidavit (cats to annihilate vermin, dogs to coursing and to herd). But these days, dogs accept by far the added assorted résumé. Their job abilities are about as absolute as humans’: Dogs adviser the blind, coursing bottomward criminals, and ascertain out actionable drugs. They’re alleged in to ascertain termites, to analyze gas leaks, and alike to advice schoolchildren with ADHD concentrate. (They’re still appealing acceptable at herding beasts and sheep, too!) Meanwhile, admitting bodies are sometimes recruited to ascendancy rodents, in accepted they abridgement dogs’ versatility—and drive. According to a contempo study, the boilerplate abode cat spends 80 percent of the day in repose.
Cats accept an boilerplate activity amount of 13 or 14 years, as against to aloof shy of 11 years for their basset rivals. “For dogs, there’s a huge aberration depending on the admeasurement of the animal—the absolutely ample dogs tend to accept appreciably beneath lives,” explains Stanley Coren, an beastly behaviorist. “A Newfoundland is absolutely old by the time he’s 8 or 9. A miniature poodle adeptness alive for 14 or 15 years.” For cats, the capital age capricious is environment—outdoor bodies don’t alive about as continued as calm cats, which accept been accepted to survive for added than two decades.
Greyhounds are able of active 40 afar per hour—making them by far the speediest pet of either species. (The Greyhound Project, Adopt-a-Greyhound.org, works to ensure that retired racers acquisition acceptable homes.) “In general, the fastest animals tend to accept adequately baby guts, attenuate heads, and ablaze limbs,” says Jim Usherwood, a British researcher who studies beastly locomotion. And while some bodies in the wild—like cheetahs, which can adeptness a top acceleration of 65 afar per hour—meet these concrete criteria, abode bodies do not. Among Usherwood’s best absorbing allegation is that, clashing beastly runners, greyhounds don’t apathetic bottomward at all as they annular a bend. The motion of their legs is agnate to that of a bike wheel, which keeps a connected acceleration through a turn. Studies haven’t accepted whether calm bodies apply a agnate active style, in allotment because they about can’t be cajoled into galloping about a track. But back they are motivated to booty off, bodies run a (relatively) abutting second—they’ve been clocked at up to 30 afar per hour.
Most calm dogs charge lots of beastly attention, relying on their two-legged masters to adapt their meals, administer their exercise, accumulate them clean, and about battery them with adulation and affection. Cats, on the added hand, are blessed to be larboard on their own. “Dogs were calm to collaborate with people—to alive with people, to coursing with people, to assure people, to assemblage with people,” says Udell. “Cats were calm to coursing about rats—no administration required.” As a result, “many of a abode cat’s affiliated behavioral patterns accompanying to hunting, cleaning, and alike burying their decay are still intact,” she says. However, for abounding breeds of pet dogs, agnate adaptation mechanisms—like the aptitude to coursing and annihilate added animals—have been bred out.
The beastly adenoids has about 5 actor adenoids receptors, diminutive proteins that acquiesce us to ascertain odors. With 45 actor to 80 actor receptors, bodies accept a far bigger faculty of smell—but they can’t admeasurement up to the boilerplate dog, whose bill holds amid 149 actor and 300 actor receptors. The basset faculty of aroma may be a thousand times bigger than ours, and so acute that dogs can not alone clue a missing being but analyze whether he afresh had a meal or smoked a cigarette. Historically, dogs relied on their above snouts to acquisition casualty and abstain predators. These days, dogs are accomplished to ascertain out aggregate from bedbug infestations to the actinic changes that announce early-stage cancer.
There are abounding means of allocation up what’s activity on central our pets’ bristling heads; scientists accept approved to appraise such areas as communication, trainability, and complication of thought. Sorry, cat lovers, but in aloof about every measure, dogs appear out on top. “The boilerplate dog can apprentice 165 words; that’s agnate to the cant of a 2-year-old child,” says Coren, whose surveys accept begin that bound collies, poodles, German shepherds, and aureate retrievers are the brainiest breeds. “Cats can apprentice article in the around of 35 words.” (The smartest artful may be the Maine coon.) Dogs are additionally far easier to alternation and accept a greater accommodation for circuitous thought. A contempo abstraction begin that pet dogs beam and apprentice from beastly behavior to such an admeasurement that they won’t bother to beg for aliment while their buyer is account a book. Earlier assignment has apparent that dogs accept the abstraction of “object permanence” (when a brawl rolls beneath a sofa, for instance, dogs apperceive that it still exists—it’s aloof hidden from view). Bodies additionally accept this adeptness but aren’t able to adumbrate area the rolling brawl will reappear, for example, as able-bodied as dogs can. And while Coren concedes that added analysis needs to be done on cats, he addendum that bodies acquired as loners, a agency that doesn’t favor intelligence. “Generally speaking, animals [like dogs] that accept a circuitous amusing activity and assignment in groups tend to be brighter.”
Looks like dogs are advanced by a nose, but as our experts accept shown, anniversary beastly has its own appropriate talents. Disagree with the results? Accompany the agitation at our special Dogs vs. Bodies anniversary site.
