<human>: I've been good friends with someone since 2000 or so. It's almost 15 years of long-distance friendship, we met online and live far apart. 

Recently, she posted on her Facebook asking for support for her sister, who is raising funds due to "a neighbor that killed our dog". 

My friend doesn't say in her post -- nor does her sister say in the fundraising page -- why the neighbor did what he did, or how. I poked into it a little bit with my friend and found out the neighbor went out of his way to hit the dog with his truck because, six months prior, he claims it had bit his young daughter. Since I had to pry this information out of my friend, I don't know all the details other than that, as far as whether or not medical attention was sought and/or pictures were taken or any of that proof kind of stuff. 

I'm an animal lover and I disagree with what this gentleman did. There were a million ways he could have dealt with the issue other than killing the dog. I don't support or condone this behavior in any way. 

That said, I'm having a hard time supporting my friend, because I feel like these details should be given before you ask for money to support a cause. Not only that, but why was the dog outside roaming free for the neighbor to hit it, at all? 

They also don't mention that the money is for legal fees to sue this guy, or anything, I think they're trying to get up money to get another dog. 

Given the details and how sketchy it all is, do I say something to my friend, or do I keep my mouth shut and mind my own business?

Can you condense the text into a few key points?
<bot>: My friend's family's dog was killed and they're seeking charity because of it, leaving out how it died or the fact that it allegedly bit someone. Do I say something?
