Me (19M) and my sister (21F) were never really on good terms. She's a despicable narcissistic bully. She is incredibly irrationally hateful. I left home after my first university year because I got a 6 months apprenticeship at a very good place. I finished it last week and returned home. My dog has become so miserable. He's unusually depressed and also scared. I took it easy and didn't suspect anything at first. But he was just so different. Last time I saw him was 4 months ago, he was doing okay. My parents took him out to socialize frequently, and he was overall taken care of, at least I thought so. Yesterday I saw in the early morning my sister throwing a tennis ball at him so violently, for literally no reason. I was instantly angry but suddenly I had a weird thought. Apparently she's been physically abusing him the past months. I asked my parents how the fuck they let it happen. They were so infuriatingly apathetic. I don't know what exactly she did but she beat him badly. I'm just fucking furious. What kind of lunacy would make anyone do shit like this... I don't know if a vet/psychologist can get my dog back. What do I do with them?
