I'm tired of this old bitch

I've decided to contact the landlord and have a talk with him in person about the ongoing fouling issue that the old bitch next door is responsible for. She's been having her three dirty mutts shit all over my side of the yard she lives an apartment down from and has plenty of space on her side of the yard for the mutts to shit at, but instead she comes all the way to where I live to have them shit and never picks it up. Today i found shit everywhere and I know it was her because she was outside before and there was no poo before the bitch came by here. I'm sick of this situation I tried telling her about in a civil manner and she started cussing me out getting defensive. I have to take other measures I'm not going to put up with this b.s anymore I've had it. I'm done with this b.s the stupid landlord is supposed to come over today to talk to me about it. I've seen her calling her dog a good girl for shitting on my porch she thinks no one is watching her but I always am.
