I am a little guy, about 15lbs. I’m mostly confident with my special human. Maybe your son has a special human? or group of humans? I know they travel in packs much like we dogs.
Sometimes when I feel threatened I growl, but I don’t think humans do that … maybe they do?
I like traveling with my pack. Sometimes it takes a while to establish the order of the pack but it’s most safe to travel in groups. We take care of each other. Have your son find his pack.
