Any way to make a dog more playful and not antisocial with other dogs and people? My corgi won let anyone pet him, never aggresive though but he hides behind me if someone tried. In stores too he'll try and hide under clothes. When were walking outside somewhere urban any black car he see he'll go to it thinking its mine and any open door he'll try to go inside.
He rarely playd with other dogs, keeps to himself and if he does play with another dog its gonna be for maybe 30 seconds then he loses interest. If im sitting at the dog park and a dog comes near me he growls.
He muchhh prefer a park over anything urban also.
I socialized him a lot more than my first dog too so idk why hes like this. Tips?
