Dogs are considered an attractive nuisance, and yes, I was a kid that was very attracted to everyone's dogs. But I was too shy to actually go up and ask to pet them or stalk them. Etc. The lady on the corner had a bunch of kids and the oldest was my age and my best friend. But her home was the hub of kid activity. I did go over one day and before knocking on the door, I started to play with her Newfoundland and his bone, like we would with my grandmother's dachshund and his slipper. I still have the scar. I never told.
My older brother is probably on that Asperger's scale, though never tested, and his wife was downright anti-social, and they had 1 boy. Consider that, both parents with social problems raising a singleton. My sisters and I all knew the kid was on the Autism scale, but it wasn't until there was a stupid fight, -- my brother's kid hit a kid with a piece of wire sleeving that smashed his science project, and the other kid beat the heck out of him. A piece of wire sleeving is kind of like a wimpy straw, it is NOT a weapon, and they had to go all the way back to 1st grade to get any disciplinary anything on my nephew, but they expelled him anyway. The other kid was a repeat offender, but knew enough about what not to say. And my brother had to jump through hoops to get him through the rest of the school year -- home schooling for a while, then he had to see a psychologist/psychiatrist, etc. My brother was surprised that they found he did have Asperger's. Really we knew it from the time the kid was maybe 2 or 3.
Folks are sometimes blind when it comes to their own kid. My brother's kid was about 13 or 14 when this happened. He is very smart, and really a good kid. Eagle Scout. Had 2 years of College behind him when he finished high school and was valedictorian. Full scholarship, and will soon be a chemical Engineer. The kid in the scenario is probably further on the scale or has some other issues.
The question is how to approach the parents. Because yes, you do want to give them an opportunity to solve a problem before making a police report. You can't really say, "Howdy, we're your new neighbors, and we would like to talk to you about your son. Is he developmentally disabled?"
I think what you do, is you be very straight-forward with them. "Hi, we are new to the neighborhood, and we are having a bit of a problem, and we would like to discuss it with you before we go any farther."
Then I would say exactly what is happening. The boy really seems to like your dog, but you would rather him not follow you, amp the dog up, or come to your house and peer into the windows calling the dog's name.
Now if the parents then tell you he has some problems, that is fine. All the better, you can ask them what you might do differently to improve the situation. Hopefully, they will thank you for bringing this to their attention. Let them know that it is dangerous for your dog and their kid -- if the dog were to go through the window, for instance. The dog is not viscious in anyway, but he might do something if he felt the house was being robbed, etc. He is only a dog. The dog can't determine your son's age nor disability if there is one.
You can go straight to the police, but I would want to know if my kid was doing this first, and have an opportunity to address the problem before authorities are called.
