Glad to hear that your bullies are strong minded too. I have a 18 week old "Tia" and she just sits on the pavement to tell me shes not going anywhere and we have a stand off until she has enough and eventually moves (our walk is only 5 mins but can take 30 mins to do). When we get to the park she loves it what she doesn't like is the getting there. She loves coming home she trots away.
