You sound like a decent dude. To really solve this problem:
Invite the old man over. You and the dog go over (prearranged) and bring your new friend over an into your house. He sits and maybe pets the dog.
Then you go over to his house and he lets you and doggie in (maybe just the doorway for doggie but so that he can see you and maybe the man pets him) and he smells a lil in the door way. You two shoot the bull for 10 mins. He gives doggie a treat better than you give him. He walks you both home. More bull shooting. Another dog biscuit.
What do you think dog owners? I know that is a bit uncomfy for neighbors to do but the dog has to see the neighbor as family. Then everytime he barks the neighbor goes up to him. "Hi ya Fido here's a dog biscuit". Pet pet.
Might work and really easy if the neighbors are already fairly close.
Now good luck. I have to get out of this thread.
