work load has a big part to play imo, if you only out once a week a half hearted dog wouldnt seem so bad but if you out most days or nites or even days an nites then a dog that aint doing its job well just becomes a pain in the arse, if you clean its shite up, feed an work the dog, then surely its upto you if the dog has failed to make your grade, but 1 mans rubbish is another mans treasure lol
