My Juno is 10 months old now, and just within the past week has started a behavior I am uncertain about. When I am walking her, if someone else is walking towards us she starts to growl and lets out a few deep barks. Is her protection instinct just kicking in, or is this something that will turn into a bad habit? She has also started growling and giving out a couple of deep barks if she sees dogs that are bigger than she is.
This is my first GSD, and up until now I've had no questions really, as she has made dog owning super easy.
Any ideas or input would be appreciated!!
