Siqaphele ngokuqinisekileyo ukuba inja yethu Thoba intloko yakho xa sithetha naye, senza umqondiso obonakala ngathi ubonakalisa umdla kwinto esiyithethayo. Inyani yile yokuba esona sizathu sokuthetha okuthandekayo asaziwa, nangona kukho iithiyori malunga nalo. Bafunda ubudlelwane beli posi kunye nenkuthazo eveliswe lilizwi lethu kwisilwanyana.
Ezinye iingcali zikholelwa ukuba lo mbutho uyaphendula kwinjongo simamele ngcono, ukuqonda amagama ethu (uphononongo lubonisa ukuba izinja ziyakwazi ukuqonda intsingiselo emalunga ne-160). Bonisa umdla kwilizwi lethu, kuba ngalo mqondiso bashiya enye yeendlebe zabo iveziwe.
Ukholelwa njalo, umzekelo, i-canine ethologist USteven LindsayUmbhali we Incwadana yemigaqo yokuSebenza kokuziphatha kweCanine kunye noQeqesho (2000), othi: "Xa inja igobise intloko, izama ukuchonga amagama aqhelekileyo kunye nezimbo, ezinxulunyaniswa nesilwanyana nemisebenzi ethile, njengokuya epakini okanye ukufumana into etyiwayo." Ingcali ye-Canine psychology u-Alexandra Horowitz, umbhali Engqondweni yenja (2011), ikwaxhasa le ithiyori.
Ezinye iingcali zithi izinja ziyanyanzelwa ukuba zihambise cabeza ngoba Impumlo yabo iyawususa umbono wabo; Ukuyithambisa bafumana umfanekiso oqaqambileyo womlomo wethu. Ngale ndlela kulula ukuba bachonge into esifuna ukuyithetha, kuba nokuba abaluqondi ulwimi lwethu, bayakwazi ukubona imbonakalo yobuso babantu.
Le ithiyori yile yaveliswa ngumphandi Igama loqhagamshelwano Stanley, ovela kwiYunivesithi yaseBritish Columbia (Canada), ngenxa yesifundo esenziwe ngoncedo lwezinja ezingama-582. Kwezi, iipesenti ezingama-60 zanikina iintloko ngexa kuthethwa nazo, nangona oku kwenzeke kancinci kunye nokuzala okufutshane, okufana neBulldog okanye iBoxer.
El imeko entle Ikwadlala indima ebalulekileyo kuwo wonke umcimbi. Sihlala sivuza lo mqondiso ubuthathaka nge-caresses kunye namabhaso, ke izinja ziphela zizidibanisa nomvuzo. Kungenxa yoko le nto besenza ngokuqhubekayo, ukuze sifumane ingqalelo.
