Fiancés Older Sister Keeps Threatening To Sue After We’ve Filed A Protection Order Against Her

My fiancé, his brother and I filed a protection order against their sister (31)because of constant harassment and threats from her because we cut contact while her dogs were in our care. Months ago, we came to an agreement with his sister that we would help her rehome one of her dogs, while holding onto the other until she somehow finds housing and has her baby(She’s been unstable for over a year now). So we drove to Alabama to pick up the two dogs, and drove them back to Ohio. It’s important to mention that his sister is not only financially unstable but mentally unstable as well…I’ve witnessed by ear, her abusing one of the dogs over the phone, and the dogs were also homeless with her for quite some time and we have evidence that she’s tried rehoming them in the past but failed to do so. We also have evidence of her telling their mother that if nobody figured out how to help her fix her internet, she was going to “dump” her own dogs. When we agreed to take her dogs we were told that these dogs were trained and understood commands and that they loved each other. This was all false. For 3 months the dogs continued to fight each other, one of them specifically would lunge at our cats at random times, and the other dog was aggressive towards people and dogs so walking them was a nightmare. We verbalized this multiple times and asked for help to send the dogs back, make a plan for somebody to get them, anything because at this point they are now a liability. Early on we had to cut contact with his sister but communicated through their mother that we would still send photos and videos of the dogs while trying to figure out a way to give them back but she began harassing us through multiple different methods even found my mothers contact, our wedding registries, made different numbers, emails, our jobs, and harassed my friends. Even in the midst of the harassment we attempted more than once to create a plan before following through with the protection order and all she would tell us was “I’ll show up whenever I want to” or “Shut up bitch” after harassing me consistently. So at that point we followed through with the protection order and rehomed the dogs. We held out for 3 months before we rehomed the first dog, and an additional month before rehoming the other dog. We attempted to come up with a plan but only received verbal abuse & threats from his sister. When trying to communicate with his mother she would lie and say somebody was on the way when nobody was actually coming, and that was a lie that was told at least 3-4 times. We have an abundance of evidence put together from our court hearings that show, not only is she unwell but we attempted to hold out and make a plan but nobody would follow through. I think it’s important to mention, that this woman has been known to cause physical harm to her own mother, bashed holes into walls with her head(we have evidence) sent videos of her hitting herself to her mom, told her brothers and mom that she wouldn’t care if they died, but has managed to manipulate thousands of dollars out her family to the point of her mother considering to filing for bankruptcy.…. Despite that, we just tried to be helpful and it backfired hard. Are we at risk of any wrong doing? Specifically for rehoming the dogs? Sorry this is all over the place it’s been a stressful year so far…I’ve got more details on the situation if needed.
