Protective at home but not in public
Dom is well socialized he goes to the store weekly and with me to drop off/pick up my son from school and has no issues but if he hears someone outside and home he goes into guard mode.
It's only when he can hear but not see the neighbors and he never tries to get to them. He will just get in front of me and growl. He just turned 6 months and still baby.
Im more of a cat person (he is my first dog since childhood) so is this normal?
