Ngokuvamile, uma ucabanga ngezinja ezinolaka, ucabanga ngezinhlobo ezifana ne-Pit Bulls, American Staffordshire Terriers, noma Rottweilers - kodwa ngokuvamile sibona ukukhonkotha okunonya noma ukulunywa kwezinja ezincane. Kodwa kungani lokhu kunjalo?
Wonke umuntu uyabazi - amagxolo anyanyekayo, lapho ngisho nezinja ezinkulu epaki zigcina ngenhlonipho. Futhi kungafakazelwa ngokwesayensi: Ocwaningweni lwango-2008, abacwaningi babuza abanikazi bezinja ezingaphezu kuka-30 izinhlobo ezahlukene mayelana nolaka lwabangane babo abanemilenze emine. Umphumela: Ama-Chihuahuas nama-Dachshunds abonise imvamisa engaphezu kwesilinganiso sokuziphatha okunolaka kubantu nezinye izinja.
Kodwa kungani ngempela izinja ezincane zivame ukuba nolaka? Ososayensi nabo bakhathazekile ngalokhu. Ayikho impendulo eyodwa kulo mbuzo, kodwa kunemibono ehlukene.
Ingabe Izinja Ezincane Zesaba Kakhudlwana?
Enye incazelo isekelwe ekucabangeni ukuthi izinja ezincane zingase zizwe zisengozini ngenxa yobukhulu bazo futhi ngenxa yalokho zikhathazeke ngokukhethekile, kuchaza uJames Serpell wase-University of Pennsylvania School of Veterinary Medicine to Live Science.
Bayoba nomuzwa wokuthi badinga ukuzivikela, ngakho-ke bayokhonkotha futhi bagqume kakhulu ngokuzivikela kunozakwabo abakhulu.
Izinja Ezincane Ziyatotoswa
Enye inkolelo-mbono iphakamisa ukuthi izinja ezincane zinolaka kakhulu ngenxa yokuziphatha kwabanikazi bazo. “Abanikazi bazalanisa izinja zezingane futhi bazibona njengezingane ezingenakuzisiza,” kusho uSerpell. Abanikazi abaningi bebezovikela abangane babo abancane abanemilenze emine kakhulu.
Kodwa yilokhu okubenza babe nolaka. Uma izinja zingafundi ukuziphatha kahle kwezinye izinja, ngeke zikwazi ukubhekana nezimo ezicindezelayo nezinye izinja - futhi zizoqala ukuzamula lapho zizwa ingcindezi.
Ingabe Izinja Ezincane Zinolaka Kakhulu Ngenxa Yohlobo?
Kodwa-ke, ukuzalanisa izinhlobo ezithile nakho kungenza umehluko uma kukhulunywa ngolaka lwezinja ezincane, kusho uSerpell. “Uma uhlaselwa iChihuahua, imiphumela iba mibi kakhulu kunalokho uma uhlaselwa iGreat Dane noma iHusky yaseSiberia,” kusho usosayensi.
Ngamanye amazwi: Njengoba izinja ezincane ziyingozi kakhulu kunezinja ezinkulu, thina bantu asikaze sibe nendaba nokuzalanisa izici ezinolaka ezinjeni ezincane iminyaka eyinkulungwane - kodwa sinezinkulu.
Ingabe Ulaka Kuzakhi Zofuzo?
Kodwa ososayensi basola ukuthi ulaka lwalezi zinja kungenzeka luwufuzo. Pho kungani izinja ezincane zivame ukuba nolaka? Ngo-2016, u-Serpell kanye nozakwabo ababili bakwazi ukukhombisa ukuthi kukhona ukuxhumana phakathi kokuziphatha okunolaka kanye ne-gene yokukhula enesibopho sokugcina ubukhulu bezinja. Ubudlelwano bungase bube ngengozi, kodwa ucwaningo luye lwabonisa ukuthi izinja ezincane zivame ukuba nolaka ekuziphatheni.
Uma kuqhathaniswa nezinja ezinkulu, izinja ezincane zesaba kakhulu ukuhlukana, zikhonkotha kakhulu, futhi zivame ukungabi namuntu. Lokhu kusekela umbono wokuthi ukuziphatha kobudlova kungase kube ufuzo, kusho uSerpell. Nokho, ngokomthetho, yomine imibono ingadlala indima.
Ngendlela: usayizi akuyona ukuphela kwesici somzimba esihambisana nolaka. Ucwaningo lwango-2013 lubonisa ukuthi izinja ezinemilenze emifushane zivame ukwesaba abantu ezingabazi futhi ziziphatha kabi kubanikazi bazo.
