When I got Taz I made the first few trips out really short. First a trip around the block and then a little treat. Next a trip to Tractor Supply and just a quick walk around inside the store. Just keep gradually adding on to what you do with her. We have several stores here that will give her a treat and make a big fuss over her. She still trembles sometimes but now I think it's from excitement. It's great that you are starting early.
