Keep taking him out for walks he needs to get used to the different sounds and people and dogs and he will get used to it and not be so nervous. Even in the winter at least take him around the block. When you walk him give him a short leash and walk him to your side not in front of you and he will learn not to pull. Take him on frequent car rides so he gets more used to ikt and he will stop barking or being nervous in the car . Chachi was exactly like him and this is what I did to get the barking to stop and to get him less nervous of different surroundings and car rides |
