You ’ve just arrived home and you find your Modern sofa in shreds and a gravid squiffy patch on the rug . Your frank literallyhas its “ tail between its leg ” and " puppy dog eyes ” . Aside from the obvious , what ’s this body linguistic process all about from an animal   behavior   perspective ?

Writing ina web log postand inPsychology Today , Professor Nathan H Lents – author ofNot So dissimilar : Finding Human Nature in Animals – explain that this is an “ apologia arc ” that is a advanced societal conduct that can be traced back to wolves .

Lents starts by explain that the demeanor has been analyse fairly extensively within savage clique . If a masher bites another masher during a play fight , this is often considered a breach of the ingroup ’s implicit societal rules . The offending masher will be “ blackball ” from the group and only allow to return if they issue this “ apology stem ” .

“ Dogs have inherited this behavior and they will use it after any kind of infraction that results in being penalise , ” Professor Lents state .

It ’s a military capability of submission , much like a bow   – the head is get down , direct centre contact is deflect , and the tail is rendered neutral .

You might think that this   could be misread as a hostile natural action , as a lowered head and a insert - in tail could be likened to a canine stalking fair game .

In answer to that , Lents close by saying : “ Facial expression and body lyric are racy forms of communication among beast and a complex array of signals can be convey with just a few gestures . The key is setting . Just like humans rarely misinterpret a grin from a tangle , animals surely understand the subtleties of their own body terminology . ”

It is n’t love whether dogs can feel guilt trip or shame in the same way human beings see it . However , a late studyfrom 2009 looking into the “ hangdog feel ” of click came to the end that dogs are   not really expressing that they ’ve done ill-timed , but rather acting in reply to the behavioral signaling of their possessor , who presumably is jolly annoyed the heel chewed up their novel trainers .
