I did tell PD that he is an issue and said a few things that have been going on--originally the dispatcher wasn't inclined to send a PD out to talk to the guy--until she asked if I had had previous issues-and I told her.
I knew that would prolly be her response when I called.
And yeah-its the guy right above my apartment.
But he goes into these wierd fits around 2 or 3 almost every morning. starts slamming kitchen cupboards around-stomping on the floors, opening his sliding glass door around 30-40 times-takes a break and opens it again another 30 or 40 times. On bad nights it sounds like he is literally throwing his furniture across the room.
But yeah, i yelled at the guy. he freaked me out, he wasn't petting the dog nicely.
he had grabbed the dogs snout in one hand and and was petting the top of the dogs head with the other hand. when I brought the dog in the house-the first thing he did was rub his face into the rug then start yelping in pain.

Hmm, I would start a journal logging everything you can about this guy and his interactions with you, your family, and your pets. Time & date of every occurence, start off with everything in the past noting what is from memory, and where all future log entries begin. (loud noises late at night count as occurences) Use this to show the landlord he's being a nuisance as a neighbor as well as to show cops if you have to call them again. I would also ask your other neighbors if they have similar encounters. I would let your kids know, they need to be with someone or with each other whenever they are going to & from the apartment. Are there any vacancies in your complex where you could move to just to not have an adjoining apartment to his?
If you don't currently have any pepper spray, I recommend you get some and start carrying it with you. You might want to add the old style can opener to your key ring. You know the kind you used to use to make one large triangle shaped hole in a soda can and then a second small hole on the other side. held in a clenched fist, this becomes a formidable weapon used to slash across an attackers face.
