My dog does not like other dogs much. With about three exceptions, as long as they leave him alone he leaves them alone and all is good. (There are three dogs locally he barks at and would pick a fight with given the chance.)
He is from rescue. I know very little of his background. He is good with people and children.
A friend visited with her dog and got upset because RescueDog growled at hers all afternoon if he got too near. Her dog "just wanted to be friends" (sigh) and my dog "has issues".
Should I take this more seriously? I don't have a need for him to be dog-friendly, provided he does not start picking more fights.
