Kukho iingxabano ezininzi malunga nekhono lobuhlakani bezinja. Kodwa ingqondo yenja ingazange ifundwe ngokwaneleyo ukuze ichaze ngokucacileyo ixesha elithile lokuziphatha kwabo. Ngexesha lokufunda kunye nokuqwalaselwa, kwafunyaniswa ukuba yeyiphi intlobo zezinja ezizizilumko, indlela izinja ezithatha ngayo kwiimeko ezahlukileyo, indlela abahlakulela ngayo iingcamango zokukhupha. Kodwa kuyafaneleka ukuba sicinge ukuba ukulinganiswa kweenja ezinengqondo kuncike kwiikhrayitheriya apho amandla abo anqunywe khona. Ngokomzekelo, ukuba umgangatho ophezulu kukukwazi ukufunda, ngoko ke izinja eziphezulu eziphezulu zikhokelwa ngamakholethi emida, okulula ukuqeqesha. Izinja ezizalwayo iBorder Collie inako ukusebenza zombini njengenja yokukhusela kunye nanjengomntwana. Indawo yesibini kuleluhlu ithathwa ngumbutho, olandelwa ngumalusi waseJamani. Ngexesha elifanayo, uhlobo olunjalo lwezinja ezinobuqili njengoko iChow Chow inendawo kuphela engama-75, nangona le nto inja iye yaphuhliswa ngamandla. Isikhundla esiphantsi kwisilinganiselo ngenxa yokuba i-chow ayiyi kuyenza ikomiti ngaphandle kokuba ibona kuyimfuneko. Okufanayo kuya kubelusi baseCaucasus, xa uqeqesho lwamanye amaqela alusebenzi. Ngokomzekelo, uMalusi waseCaucasus akayi kukhusela inkosi ekuqeqesheni evela kumhlaseli wokuqala. Uqonda ngokucacileyo ukuba akukho ngcipheko, kodwa ukuba uyakwazi ukuphazamisa kwaye uyakholelwa ukuba ukuhlasela kuyinyani, ngoko umhlaseli uya kuba yingozi kakhulu, kuba inja iziphatha ngendlela engalindelekanga kwiimeko ezinjalo. Kuyafana noLaikas. Benza ngokusekelwe kwimeko, kwaye bangayithobeli. Oku kuziphatha akubonakalisi izinga eliphantsi lolwazi. Kwangexesha elide ama-huskies ayenamalungu omntu kwiimeko ezinzima ezisenyakatho. Abantu babefanele bathembele kakhulu kwizinto ezintle, ukuvumba nokuvalelwa kweenja zabo, ngokomzekelo, inja e-harness ingayeka okanye ithathe inkosi ngokufanelekileyo nakwezinye iinqununu ukuba zivakalelwa ingozi, umzekelo, ukutyunjwa kwiqhwa. Ngaloo ndlela, baye benza ukuqonda okuthile malunga nolwalamano nomntu, ukungeniswa okungekho nto kungabonakaliyo kulolu hlobo, kodwa ke amandla abo okwenza izigqibo zabo kwaye benze ngendlela efunekayo kwiimeko ezithile kubonisa ukuba banamakhono akwiqondo eliphezulu.
Uhlobo ngalunye lweenja lwalukhutshwa okanye lugxothwa ngumntu ngeenjongo ezithile, ngoko ke kunzima ukucacisa ukuba yeyiphi inzala. Umzekelo, nokuba inja eyona ingqondi, inqabileyo yokukhusela, ayikwazi ukunceda ekuzingeleni, kunye nenja yeqabane, oqondayo inkosi yakhe kwisiqingatha-magama, uyazi amaqela amaninzi, akanakulusa, okanye alugcine kakuhle indawo. Yingakho kungenakwenzeka ukufumanisa ukuzaliswa kweenja eziyingqondi. Kwakhona akunakwenzeka ukufumanisa ukuba ngubani ontle kunenqatha kunekati okanye inja. Iikati zihluke ngokupheleleyo kwimeko, cinga ngokungafaniyo kwaye uqonde ulwazi. Ngaphezu koko, ikati ayiyi kwenza nantoni na into ephikisana nomnqweno wayo, nokuba ngaba iyaqonda into efunekayo kuyo. Inja eyilumko ingenakho ukwenza imiyalelo engabonakaliyo, kodwa isenzo sakhe nesimo sakhe sengqondo
Ukongezelela ubuchule obuvelayo kuluntu oluthile, kuxhomekeke kwimfundo nakwimfuyo. Nangona inja eyingqondi ngakumbi, ukuba ingafundanga kakuhle, ingalahlekelwa yimpawu zayo. Ngokomzekelo, i-retraver yeLabrador ithathwa njengenja elinganiselayo kwaye iqeqeshiwe, esetyenziswa njengenja yokukhokela yokunceda kunye nenkonzo yamapolisa. Ngoluhlu lwezinto ezintle, iLabradors ihlala enye yeendawo zokuqala kwiimanani zokuhlaselwa kwabantu. Oku kuphazamiseka kuchazwa ngento yokuba, benethemba lokuba umgangatho wobuhlanga, abanini abazange bahlawule ngokufanelekileyo imfundo, okwabangelwa ukungathobeli kunye nobudlova. Ukuba ngaphambi kokufumana i-puppy, abanikazi bexesha elizayo bayazi kakuhle iimpawu zabo, kufuneka bafumane ixesha elingakanani lokuqeqeshwa, yintoni ekukhuliseni kunye nokunonyanzela kuyimfuneko yokwenza inja, kwaye baya kuba nako ukukhetha udidi olufanelekileyo kwaye bakhule inja ehlakaniphile.
