I'm teaching Bobby 'off' when he's on my chair, initially wth a treat 'lure', now a treat when his paws are on the floor. Should I keep up with the treat reward inefinitely? I don't mind hm being in my chair when I'm already on it as he will snuggle up next to me but if he's on it when I want to sit down he needs to move out of the way or get sat on ! ( that would be no joke!) Reena wiil move right over to one side to make room as soon as she sees me, but not Bobby, Though he he has started to move in anticpation of the treat which is always accompanied by the word 'off' and a hand signal. Any tips?
