Angel is 4 months. Every time I try to put a collar and leash on her she just sits there. I have tried to get her to walk with me. Is she to young yet? I also take her out to potty after naps, meals, before and after bedtime and she goes most of the time but I have to literally pick her up and take her outside. I have been trying to get her to walk out herself but as soon as she sees the door she runs the other way. It is very strange. I am affraid she will not train easily because she doesn't go to the door by herself. Have any suggestions?
