alrite. before anyone jumps down my neck saying i shouldnt have dogs if i dont no what i am doing, i was wondering if the fundermentals were the same with terriers as with my labs ( i have never owned a terrier but alway had labs) i.e start training at about 6 months ( obedience) then the two breeds differ from there. would you lads introduce them to rats at about 7-8 months? i am hoping to get these dogs to respond to come back whistle as i am also going to use them for bushing in the season but also digging ( i know the whislte wont work there lol). if i am wrong with what i have said pleas
