Kendall is going out for short walks now. However we are finding he is unwiling to leave the house and go to the top of the road, but once on the park he is fine, and is fine all the way back. He just sits down and doesn't want to walk. If I take him to a walk in the car he is fine as soon as he gets out. Not sure if its just that he doesn't want to leave his house where he is comfy, safe and warm. A dog trainer has said to drg him but not really happy with this advice. Do you think I am OK picking him up for the first bit of the walk, or is this giving him bad habits?
