well i have to admit im my case i kept the dog for 2 year so if he wasnt goin to do it after 2 year i reckoned he wouldn do it all
some might not mate as we all know some dogs just aint got it, but half the battle is entering the dog correctly, i wouldnt shift a dog at 2 most will say it should be takin them at 2 etc, some just cant be bothered waiting and trying and the dog f****n about and doin this wrong and that wrong so just get rid of it and each to their own we all do things differently, in all the cases iv seen perseverance has paid off so if i was in this position id be out
