Grandparents dog from hell

Victoria • Almost 20 engaged to the most amazing man. Just trying to get by.
I am eighteen and live with my grandparents. I moved in with them in May to be in the same city as my long term boyfriend, get away from my parents split, and college. The room is kinda small and half my closet is taken up by my grandmothers clothes (she has five closets filled if clothes and because she doesn't know what she has she ends up buying duplicates) but that isn't my issue really cause I live here rent free and they got me a car when I moved here along with helping pay for my college. It is truly pretty awesome here except for one thing. My grandparents fucking dog from hell. She barks at anything has no discipline and thinks she is queen shit. (She is a toy poodle) anytime a leaf falls outside she barks, she wakes my grandfather up there to four times a night to go outside only to walk out the door and come back in, any time she so much as sees my boyfriend she just barked like crazy no matter what we do (she does this to a few people and has started to do it to me) treats don't help we have tried. They got a bark collar that sprayed he with something but she was "afraid" of it so they didn't use it anymore. They now got a shock collar for barking but barely give it a try and have the wrong metal prongs on it tonight. They don't follow through with the training yet drop tons of money on it. Seriously wtf. This dog if 4 fucking 4 what the hell. Well tonight the dumb bitch starts randomly barking at like 1 am waking us all up including my dog who has a pretty deep bark but listens when you tell him stop. Well cause she woke me up I had to pee so I'm trying to get out of my room to pee and the door makes the worlds smallest creek but she just goes crazy and causes my dog to bark and my grandfather to get up a second time and this time shut their bedroom door with her locked in there. I hate this dog. With every fiber of my being I wish she would run away or something she is such a pain in my ass. Plus she breaks into my room and eats my dogs food. She also has taken to peeing in the living room but my dog gets blamed for it cause their prescious angle couldn't do that though she was the only dog out when the crime was committed and also my dog gets blamed for shits their dog takes in the house which gets me in trouble and again they don't believe me. Ugh this dog I swear this sounds awful and I hate to say it but I kinda want her dead at this point. She constantly wakes me up. I work late shifts and sleep during the day and at 9 am she is barking nonstop at my grandfather in the back yard and when I try and put her out with him she bring her back in because I quote "I can't handle her barking you are just gonna have to deal with it." Not my dog and I'm sorry but I worked all night and need some damn sleep cause I have another eight hour shift like what the fuck. I love my grandparents but their dog ugh. I can't wait to have money to move out with my boyfriend cause I am so damn ready. Anyone got tips on how to shut this damn dog up and train it without putting it to sleep. Plus treats don't really work for her.
