After a good session at the dog class last week where Gremlin misbehaved again and Ian and I were put in our places for not being strict enough, we have started to adopt a zero tolerance approach to Gremlin. That means he doesn't get anything unless he does as he is told first time. We are trying our best to be good pack leaders. It does seem to be working although I am cautious as Gremlin does seem to have a habit of working out our latest tactic pretty quickly and then either ignoring it completely or finding a way to disobey!!
