I don’t butt into other peoples lives. They choose to live in a bio hazard that’s on them. I don’t smell anything thankfully because I’m 99% sure their dog isn’t allowed in the bedroom which is the wall we share. But I’m 100% sure they don’t take him out because I was working from home for a while and hear clearly when they unlock and open their front door. It never opened. Either they use a cat liter for the dog, or it just shits and pisses on the floor .
