A lot or a little? Wolves discriminate quantities better than dogs

Being able to mentally consider makes sense for any social species. This skill is important during the search for food, for example, or to determine whether an opponent group outnumbers one’s own. Scientists from the at the studied how well can between different quantities and discovered that perform dogs at such tasks. Possibly dogs lost this skill, or a predisposition for it, during .

About Dogs

The results were published in the journal Frontiers in Psychology.

People and animals have been shown to discriminate between quantities. Lions, chimpanzees and hyenas, for example, will only approach a group of attackers if their own group outnumbers that of the intruders. These animals use numerical information to make decisions about their social life.

Testing numerical competence

In 2012 (To the article “Quantity discrimination in wolves (Canis lupus)) and Zsofia Vir?nyi from the Messerli Research Institute at the University of Veterinary Medicine Vienna showed that wolves are capable of discriminating between different . In their present study, they asked whether dogs also possess this skill or if this form of numerical competence was lost through domestication.

For the study, Range and her colleagues from the Department of Comparative Cognitive Research tested 13 crossbreed dogs raised at the Wolf Science Center in Ernstbrunn. The animals are living there together in different packs. The researchers tested the dogs for their quantity discrimination skills by presenting pieces of cheese. Those pieces were sequentially placed into two opaque tubes — one on the left and another on the right side. Eventually, the dogs had to decide which tube contained more cheese pieces than the other. By pressing the correct buzzer, the dogs were rewarded with cheese from the respective tube. Furthermore, the dogs did not see the person placing the cheese into the tubes, which excludes the human influence as a factor.

“We deliberately performed the test in such a way that the dogs never saw the full quantity of food at once. We showed them the pieces sequentially. This allows us to exclude the possibility that the dogs were basing their decisions on simple factors such as overall volume. The dogs had to mentally represent the number of pieces in a tube,” explains first author Range.

Dogs performed worse than wolves

Range and her colleagues compared the results of the wolf test with those from the dog test. The comparison showed that dogs were unable to discriminate between difficult comparisons such as two pieces of food versus three or three pieces versus four. The wolves, in comparison, fared much better. “Dogs are better able to discriminate the quantities of food when they can see them in their entirety,” says Range. “But this requires no mental representation.”

    This list is all wrong, also put together by some one who doesn’t know the
    physiology of dogs. 1st glaring mistake and the one i see must ppl replying
    make is this. Their is no American Bullie. it’s the American Standford
    shire Terrier and American Pitt-bull Terrier (APBT). And their is no way in
    hell that the dogs placed above the Dogo Argentino have the muscle mass to
    out class a Dogo. They may be big, but pound for pound the Dogo can and
    will out preform the majority of dogs on that list. And as far as AmStaf vs
    APBT goes. AmStaff has more muscle mass, but do to that mass they get
    winded far quicker then APBT. Same for Rots, they don’t have the stamina to
    keep up. Proof in point. APBT hold the majority of the UKC super dog
    tittles. However by far the dog with most stamina and work drive no matter
    how bias i may be for my APBT, and Dogo’s, the husky will out run them all.
    So again this list was put together by some one who has no idea of the
    physiological make up of canines. Ask a vet. O wait u just did.
    typos sry. Ima vet not an English teacher.

    Was ist denn das f?r ein Bullshit? Wo ist der Cane Corso,wo ist der
    Dobermann? Wo ist der Bully Kutta? Wadd f?r eine Scheisse!! Und dann noch
    der Central Asiatische Sch?ferhund vor dem Kaukasischen!!!
    Du Vogel hast keine Ahnung tausch den Tibetan Mastiff wenigstens mit dem
    Boerboel und es ist ein bisschen besser…

    I still can’t believe that on the clip you put: Pit, Buldog,Husky …
    Where are Kurdish Kangal,
    Mastiffs(Corso,Presa,Kutta,Neapolitan,Tibetian,English, Bull),St
    Benard, Antolian Shepherd, Sarplaninac, Bandog, Tosa, Leonberger,Fila,
    Bulgarian shepherd, Karakachan … LOl
    The bullies aren’t stronger than pit’s compared on 4 components:
    agility,strengh,stamina,speed they loose on 3… I’m thinking that the
    whole package have maybe Dogo,Corso,Presa,Rott,Kuta,Karakachan,Fila,Kangal
    (both Turkish and Kurdish), St Bernard and Alabai (Central Asian
    Shepherd)…

    I think the dogo should have been higher. Also, I know dobermans are more
    built for speed, but surely they’re more powerful than a german sheperd? I
    could be wrong on that one, but ever Doberman I’ve been around was has been
    a beast

    This list is retarded. First off a PitBull always have a red nose otherwise
    it’s a Staffordshire. The red nose is the breed marker. And your pictures
    of huskies are clearly malamutes. Second of all there is no difference
    between a Caucasian Shepard and a Tibetan Matsif even the breeders
    acknowledged that they are just praticularly agressive Tibetans. Thirdly
    there is no standard here. Strongest bite force? Stongest physically? Best
    at fighting? Most adaptable? And even if it was its compleatly biased. And
    you said every breed fights eachother. But in what climate, is it a cage
    match or does trainablity play a factor. Why isn’t the tosa in it at all if
    its about fighting? There’s also no way a rot will beat a pit. They are
    bigger but have no stamina or agility. Why do you think a husky would beat
    a Doberman? And lastly who supplies a shit what breed is a better fighter?
    Better guard dog sure, better attack dog, yeah. But if its just about
    fighting then its completely useless. Just because a dog is good at
    fighting doesn’t mean it will have a use.

    there is only 9 dogs in here. the american bull dog and the pit bull are
    the same thing. the pit bull was given the name american bull dog when
    people wanted to enter them in dog shows but the snooty people didn’t like
    the name. The american bull dog and the pit bull are the same dog.

    Actually we want to get a little more detailed here kangal is a Armenian
    dog because there was no F*ing turkey country. All that land is Armenia.

    no mastiff’s you gotta be joking me right? they have the most powerful bite
    of any dog breed coming close to 700 psi of bite force ! not too mention
    are usually 200 pounds+, and what about the saint bernard? it is used in
    the mountains to haul around injured/dead people and is also the second
    largest breed, i can see why a dane isnt on here because they are skinny as
    all hell and fragile but not the other 2 come on !

    Where would You put African Wild Dogs in this? Or is this more about
    Domesticated Dogs?

    Bite force goes…
    1. German Shepherd
    2. Rottweiler
    3. Doberman
    All three German breeds.
    Many studies have been done and the GSD had the strongest bite force,
    upward of 790 pounds. American Bulldogs have the ability to clamp on and
    lock, but a Shepherd has the jaw structure to bite down similar to a shark.
    Strongest dog breed would be between a Mastiff and a Akita. Akitas are very
    large and very, very strong. They get upwards of 150lbs.
    Just what I’ve seen and experienced with my Doberman and GSD.

    im not a dog owner or dog expert, but if id ever get one i think i would go
    more along the lines of loyalty & intelligence. but really i would just
    like to get a Siberian husky or maybe a Labrador or even a kangal now that
    i know about it. maybe one day i might consider getting a rescue dog tho i
    didnt event know about these breeds but now i know a little more ^-^

    Really? Tibetan Mastiff wasn’t even up there or a Great Dane…..Are you
    joking?

    • Larz
    • December 19, 2014

    I call bullshit on this list. Strongest dog or strongest jaw? If you’re
    talking strongest dog, Mastiffs and St. Bernards will be topping out this
    list and dogs like the Pitbull won’t come close to making this list because
    they are medium sized dogs that run around 40 lbs. If you’re talking bite
    force, or jaw strength, National Geographic did a study on this and came up
    with 1) Mastiff, 2) Doberman, 3) Rottweiler, 4) German Shepherd, 5)
    Pitbull. I think I’ll trust National Geographic’s research over yours.
    Interestingly, Timber Wolves had a bite force twice of what the Mastiff’s
    is.

    American Bullies are way bigger / stronger than the American Pit. My
    family always owned Rots and I broke the cycle and got an American Bulldog
    and they’re the shit compared to a pit. I literally have 100 people asking
    how I got my pitbull so beef when I’m out with him. They’re basically a pit
    bull and a half. Much taller in stance and mass. It’s all about genetics
    really though, I’ve seen some pretty big pits too, It’s not like that.
    Backyard breeders have murdered that line for the most part, I would never
    buy a pit unless I could trace it’s lineage.

    I think its a tie between the Caucasian shepherd and Kangal, But I think
    the Shepherd would win because he is more like a hero while kangal is the
    villain because its turkish
