Lucy is a 10 month Puggle that we have had about 2 months. She doesn't want to go out into the fenced yard without me or my wife and she still takes a bit of coaxing to get her out. She likes it out there with someone and sometimes even alone but getting her out there is a chore. She is house broken and at times she claws and whines at the door but when you open it she won't go out. I have spent time with her in the yard and then gone in the house, She then wants in. There were times I let her in and times I made her stay out for a while. Its like she doesn,t trust me to let her in again. Any ideas why she acts like this and what should I do about it.
