This fukin moron has moved in the apartment below me.. He has a dog, that is barking, howling non stop for 10 hours a day.
Dude, stop. Let me a tell you a little story. Relax.
I was renting this apartment on a 3rd floor, 3 bedrooms, all nice, all mine, cheap, landlord old lady, and I was a very good tenant that paid all his sh1t always on time, which is rare around here. I was valuable to her. I was nice guy and clueless and sh1t, back then, there was no evil sh1t in me. Apartment directly above me got sold, I guess, and new folks had a tendency to walk in high heels early morning and late evening, also jumping and sh1t, it was loud, and it was causing me problems with my rest and peace. So I banged couple of times on the ceiling, which had pretty much little effect. I did complain to landlord as well. I even complained to the lady that oversees all the sh1t in the building, she told me they were crazy. So one night I got really drunk, and I fvcking lost it, I used a syringe full of super glue to glue up their door lock, and the doors around here are full metal. The next morning they had to call in fire rescue to get it open. It was nuts. Obviously since I complained and knocked everybody thought it was me. They called the cops, cops called me, I said it wasn't me, back and forth. But they couldn't prove it. But I did get hell from police. In the end, I had to move out, it was my own decision, I wasn't forced out.
So my advice, since you already showed your concerns, anything you do will point towards you. In your particular situation you should move out. Otherwise you will get in trouble. Kicking someone's ass will get you in trouble, don't do it. Do not take this as a defeat. Trust me on this one, you will find better places and meet new cooler people, just like I did.
Now, before you move out, you could poison the dog with some rat poison, just have to use a lot. You'll find ways.
Now for the future, never fvcking complain. Never do anything directly. Always remain incognito. There is a dog that's bothering you? Poison it. There is a neighbor that's bothering you, fvck with him, anonymously.
I now own my own apartment, and my upstairs neighbors, several floors up, used to throw trash out of the window, some of that trash landed on a tree next to my window. I just grabbed the trash, and stick it into their mail box. Guess what, they aren't throwing trash out of the window no more. Another instance my upstairs neighbor's dog took a sh1t on the staircase, and he didn't remove it. I took that piece of sh1t and stick it to his door handle, I see no more dog sh1t on the staircase. Neighbor in a building next to my apartment has a moped with an alarm which goes off all the time, especially during the night, I jammed it using VHF transceiver on frequency 433.9200, he couldn't start it and was late for work I guess, several times, and then he couldn't lock it for the night. He is not using the alarm no more. I am 100% incognito. I don't give a fvck.
In my suburban house I had a neighbor set my fence on fire, run after me trying to kick my ass and sh1t, I called police. He send his son after me, I called police. Then I find out he was searching for some sh1t against me to get me off the road, to send me to prison and sh1t. I knew some sh1t about him, tax evasion and stuff. Guess what, he is now in prison himself. All the while, I just made it appear that I made peace with him, and hold no evil towards him. Fvck him.
Do not be direct in your confrontations, there is a place and time to be direct, but not with your neighbors. When sh1t gonna happen, first person you will run to will be your neighbor, not the police and the authorities.
