With their heavy , muscular bodies , frump such as Rottweiler and pit bulls , specially those that are direct to act menacingly , may seem like the scariest of their species . But grounds shows that smallerdogscan really be more aggressive than many of their outsized counterpart .
So why are small dogs so fierce ?
This Chihuahua isn’t messing around.
First , it ’s crucial to delimit what bet as tiny for a hound . " Small dog in the less - than-20 - pound [ 9 kg ] range lean to be more reactive , " said James Serpell , theatre director of the Center for the Interaction of Animals and Society at the University of Pennsylvania School of Veterinary Medicine . For example , dachshunds , Chihuahuas and Jack Russell terrier are the most likely to attempt to bite , according to a 2008 work in the journalApplied Animal Behaviour Sciencethat survey the owners of more than 30 dog breeds . Other aggressive behaviors run into in small dogs include growl , snarling and lunging . There are a few theories for why this is the case .

lowly sizing may make hot dog more fearful , and they may trounce out in self - defense , Serpell aver . Tiny breed may be more probable to react defensively because they have more to be afraid of .

Alternatively , minuscule domestic dog ' responsiveness could be a solution of their possessor ' behavior . " possessor lean to infantilize belittled dog breeds and guess of them as being like helpless infants , " Serpell secern Live Science . Pet possessor may be to a fault protective of low breed , so they may not socialise them or teach them how to properly oppose to stressful situations .
aggressiveness could also be bake into the pups’evolution . " If you ’re attack by a Chihuahua , apparently the consequences are much less significant than if you ’re attacked by a Great Dane or a Siberian husky , " Serpell said . In other words , over the millenia , humans may not have bother to breed strong-growing behavior out of fiddling frankfurter because the effect were n’t as horrific as they were for being attacked by goodly hounds .
That last possibility is supported by subject that have find alink between aggressive conduct and the increase factor genethat make small-scale pawl small . The connexion could be cooccurring , but inquiry has shown that small dogs are n’t just more extreme in their aggression - interrelate demeanour ; compared with large dogs , small dogs tend to have more severe detachment anxiety , ordinarily skin more and are more probable to urinate in the house , Serpell said . This chip in credenza to the theory that genetics play a role in small hot dog ' extreme behaviour .
Scientists are n’t certain which of the theories are right because they have n’t studied the root of lilliputian dogs ' bowelless behavior yet , Serpell said . All of the theory could potentially play a use .
Some lilliputian breeds are an exclusion to the rule . One example is the Coton de Tulear , also known as the Royal Dog of Madagascar . This dog is small , ashen and fluffy , like to a bichon frise .
" For some rationality , that breed seems to have quite quiet behavior across the board , but it also has all kinds of medical problem , " Serpell said . " It ’s unclear whether that ’s because they perchance lack some criticalgeneticfactor . Or it could be touch on to the fact that they ’re just more unhealthy and less physically able to respond powerfully . "

Some fast-growing behaviour can be address safely while living with the dog , but a professional frankfurter flight simulator should be the one to work on correcting the behaviour , according to VCA Animal Hospitals , a organisation of creature hospitals .
torso sizing may not be the only attribute of modest dogs that is link up with aggression . Lower height alone is associated with undesirable trait in some breeds , according to a 2013 cogitation in the journalPLOS One . For case , dog breeds with short legs are more likely to be fearful of unfamiliar dogs and to have owner - directed aggression . It ’s unclear why this is the display case , but it may be something to keep in nous when you ’re looking for your next ducky .
