My boyfriend’s 5 year old pit bill is EXTREMELY aggressive and does not listen AT ALL! She is VERY dominant and jealous of my 10 year old akita, she humps him and tries to take over on his doggy bed even though she has her own bed! She doesn’t like ANY other dogs and WILL attack ANY dog (including little puppies). She has gone after 2 little girls already (successfully bitten one in the face). She does not like me, she does the exact opposite of what I tell her, if I try to discipline her she runs and hides behind my boyfriend or just tries to bite me, she runs and hides under the table or bed and tries to attack me if I simply attempt to put her outside. She has already bitten me once and tries to go after me EVERYTIME my boyfriend and I play around (like she can’t tell the difference between playing and real fear). You can’t eat in front of her because she gets RIGHT up in your face and just begs non-stop, she pees and poops in the house, she digs and tears up the trash all over the place EVERY chance she gets, we have been battling to keep her off the furniture for about 3 years and still she is up on the couch the first 5 minutes we leave her alone! The thing that gets me is she knows when she is in trouble but yet she still continues to disobey?! We have tried SO many different disciplinary techniques but she responds to NOTHING (one time she tore up the trash all over the back yard 3 days in a row even though she got disciplined everytime and knew she was in trouble, she still does it) My boyfriend spoils her and thinks all her behavior traits are normal and ok so he never disciplines her or takes responsibility for when she is bad, I know this is half of the problem. My question is….Is this dog just an untrainable lost cause? Will she EVER stop misbehaving? I don’t know what to do anymore and this dog causes SOOOOO many problems and arguments between my boyfriend and I and I don’t want to break up with him over his stupid dog but he will NEVER get rid of her (even if she attacks ANOTHER child) I really just don’t know what to do?! HELP!! TIPS OR POINTERS?!
