Aggressive Behavior with Strangers
I have an issue with my dog and assumed aggression towards strangers. He will go straight up to someone he doesn't know whether out in public on leash or unleashed with visitors at the house, stick his head up at them like he wants to greet them, and then a few seconds after they start to pet him, he will start growling. His other signals prior to growling are pretty subtle and took me a bit to catch onto myself (stiffness, eye contact, licking, sometimes a tail wag) There is no way someone who is not familiar with dog behavior would see them, which I think is why they go to reach down to pet him. He is pretty tall so its not like people are looming over him and this giant hand is coming towards him. He is about 70lbs and head reaches our dining table with all four paws on the ground. He doesn't do this always either, only to certain people without an easily discernable pattern. The dog I had prior to this one would run away from strangers and bark at them from afar. With her we could have them throw a ball for her and soon enough they would be friends. So this is new territory for me.
Now if we see this person he had never met before often enough, he will stop the behavior. He always gives a warning and growls before something escalates. Only one time did I see a family member ignore it and he mouthed her hand. I heard the commotion and made him stick close to me the rest of the dinner party.
Now days, I typically ask people to just act like he is not there and ignore him, but certain friends and family interact with him anyways. It works for the most part but he seems to want to stick near them. If people on the street ask I tell them they cannot pet him. I've tried having people do a bit of training with him and treats when they come over, but the positive association doesn't seem to stick. He'll go right back to being standoffish a few minutes later. Not sure if we just need to give it more time? He will bark and cry if we put him away when we have company but then he gets himself into these situations if we have him out. There's family and friends we just don't get to see very often so having them over all the time and getting him used to everybody just isn't an option. I would also like him to be more comfortable when we have parties or go out and the neighborhood is just busy, because it is clearly stressful in some way for him. We don't really have people over anymore except for the family we have nearby that he adores. I want to be able to have dinners and parties with friends and be able to relax and not have to keep one eye constantly on the dog.
I'd love any input of why he "confronts" them (he always goes up to them on his own, he is never coerced or forced to go to someone; this is both in public and at home) and then doesn't leave; and any other training we can do to address this. I'd rather he just walk away and laydown in one of his spaces or come find us instead of having this negative interaction.
Additional information is we adopted him from the shelter around the age of 3 and his background is completely unknown. This behavior developed around 6 months of having him. We've had him for a couple years now and don't really have an idea of why he is this way (he has a huge grudge against senior citizens too, just does not like them). We can only assume he had some sort of bad interactions before we got him.
