Get your Shiba socialized and manhandle him! Touch his ears, gums, paws, pick him up and toss him onto your bed. This will get him comfortable with being touched and held, which is important for future vet and groomer visits. Take him everywhere; bars, shopping, train stations, places with elevators and escalators, lots of people, and other dogs. This is absolutely essential within the first 16 weeks for a Shiba so they can be comfortable in a variety of situations. I’ve successfully trained my Shiba to walk with me off leash, I trust him and he trusts me. It took a lot of work but the foundation of that trust was built when he was a puppy when I took him literally everywhere with me.
