Mate your talking shit there are MANY fox dogs that will take as much as you can show them and be just as keen for the next hardly a mythical standard. To me you seem the type of person that keeps a dog wether its a jacker or not which is fine but there are people who have dog for work if they don't they are PTS some wankers dump them but not me or many others. Also you think seem to think putting time into a dog is going to make the dog 100% percent on what you want and stop it jacking? F*ck knows where you got that one from
