Anyone ever have a pup who was nervous about going into stores? He balks at the door but will come in if I bend down and tap on the floor. I'm going to do a lot of work with entrances, lots of high value treats. He's always nervous at first, but seems to recover pretty quickly. I'm thinking he may be entering the beginning of a fear period. Should I still take him out a lot or scale it down and just go to evaluate his responses?
