Ngokuqhelekileyo ukuziphatha kakubi kwenja kuchazwa ngezizathu ezithile. Oku kungabikho kwemfundo efanelekileyo, okanye ubukho bezinto ezicasulayo. Ngokuqhelekileyo ukuqeqeshwa ukuqeqeshwa akubandakanyi ukuziphatha kwenja.
Kodwa i-cynologists ikholelwa ukuba ezinye iintlobo zithandana nobugqwetha ngokwemvelo.
Ngokwezibalo zokuhlaselwa kwabantu, inzala enkulu yezinja iyinkunzi yenkomo. Inkunzi zeenkomo zinemihlathi enamandla kakhulu, amandla okunyanzelisa okuyi-126 kg. Ukuwagxotha nge-bite kungenakwenzeka.
I-Rottweilers nayo ithathwa njengento enobudlova. Baye baxothwa ukukhuselwa, ngoko ke inja zale nkcubeko ingaba nzima kakhulu kwiimeko zokukhusela ummandla wabo okanye umkhosi.
Kwaye nabalusi baseJamani, ababethatyathwa njengezinja ezihlakaniphile nezolileyo, ngokungabikho kokusebenza ngokomzimba kunokususa amandla angqongqo kwabanye.
Ziziphi izinja ezigqithiseleyo kwiimbono zesayensi?
Iingcali zenzululwazi yaseYunivesithi yasePennsylvania zihlanganisa uluhlu lwabo lwezinja ezigwenxa.
Olu phawu luyinhloko yentlawulo. Ekuqaleni, zaxothwa ngoncedo ekuzingeleni iibhegi. Ngoko ke, ulwaphulo lwabo egazini. Kwindawo yesibini yi-chihuahua, kwaye kwisithathu-iTerrier Jack Russell.
Omnye wabalobi besi sifundo sithetha ukuba iintlobo ezincinci zizaliswa ngokugqithiseleyo. Kuze kube ngoku, zonke iinani-mali zisekelwe kwiinkcukacha malunga neenkcukacha zokubetha. Kodwa ukubetha kweenja ezincinci akuvumi ukuxelwa, ngoko ngokukhawuleza ukuba ukuhlaselwa kwezinja ezinkulu ziphela ngoncedo lwonyango.
Iingcali zezinja zithi isizathu esiyinhloko sokugonywa kweenja zasekhaya ngumxholo wazo olungalunganga. Ukuzingela kunye nezinja zokulwa azikho kwiindawo zokuhlala. Kufuneka baqeqeshe ngokufanelekileyo kwaye baqeqeshe njalo. Kwaye abalusi bazalisa kakhulu kwiindonga ezine, bafuna indawo.
