Hi I will be getting a little female GSD puppy and want to poddy train her with a crate in the beginning. I already have the largest size wire crate with the two doors and a divider if needed. I will use this for her when she is bigger and we have to go away for a while. What I wanted to know is just for the beginning what size crate would you recommend for poddy training. I have read you don't want it too big but I don't want it too small either. I have been looking at many and was thinking that maybe a 28"long X 20.5 Wide X 21.5 High would be a good size? There is so much to choose from it gets rather confusing. Just thought maybe some of you could tell me what you used. Thanks for you help!
