I have the sweetest Labradoodle, Abbie. She's 5 months old and is very playful with other dogs and friendly with humans. She is however not comfortable going into new buildings (i.e. other people's houses, my office, stores, etc.). She's also petrified of stairs (when there are more than 5 steps). Any suggestions on how to integrate her into new environments without it being so traumatic? Not sure if something happened before I got her two months ago.
