Kukho abo baqinisekisa ukuba bayahlula ngokwahlukileyo iimvakalelo en imbonakalo yobuso benja yakho, into esengqiqweni ngokupheleleyo ukuba sithathela ingqalelo into yokuba kwanezona ngcali zibalaseleyo ziye zenza izifundo ezibonisa ukuba ezi zilwanyana ziyakwazi ukuveza iimvakalelo zazo. Ukuhleka yenye yazo.
Sivame ukubona ukuba uhlobo loncumo lwenziwa njani ebusweni babo ngalo lonke ixesha bedlala, behamba okanye beziphumza emva kohambo, into efana naleyo yenzeka ebantwini. Le nyaniso yaqala yafundwa Isazinzulu uKonrad Lorenz, othe: "xa incumile, inja ivula imihlathi kancinci kwaye ibonise ulwimi kancinci." Yile nto ayiphumezileyo lo mdlali wawongwa ngembasa kaNobel kwiMedicine kwincwadi yakhe ethi "Man meets dog", 2002.
Kutshanje, ngo-2011, iziphumo zophando zikhokelwa ngu UNjingalwazi uNicholas Dodman, ovela kwiCummings School of Veterinary Medicine kwiYunivesithi yaseTufts (eMassachusetts). Uqukumbela ngelithi ezi zilwanyana ziyakwazi ukuqonda iimvakalelo kunye noncumo, zenza ubuso ngemilebe yazo. Uqhubeka esithi banoluvo lwabo lokuhlekisa.
Ngakolunye uhlangothi, Ingcali yokuziphatha kwe-canine uPatricia Simonet, waseYunivesithi yaseSierra Nevada (eUSA) wafunda "ukuhleka" kwezinja zisebenzisa imibhobho enamandla, ukuzirekhoda ngelixa zidlala. Uye waphawula ukuba ukuphefumla kwabo kwahlukile xa besonwaba kakhulu, bephefumla ngakumbi. «Kwindlebe yomntu engafundiswanga, ukuhleka kwenja kuya kwenza isandi esifana nesi yhu, yhu«, Ucacisa uSimonet.
Ukuba sijonga kufutshane, siyakwazi ukwahlula phakathi koku kuhleka kunye noncumo kwisilwanyana sasekhaya. Siza kubona indlela wolula imilebe kwaye uphakamisa iikona, uvula kancinci umlomo uveze amazinyo nolwimi. Zonke zikhatshwa kukuhamba phambili kunye nokuhamba msila ngokukhawuleza. Izakuzibonakalisa ngolu hlobo ngakumbi ngexesha labo lokudlala nathi kunye nezinye izinja.
