I argued with my sister after being bitten by her neighbor's dog

I went to the Central Highlands province of Gia Lai for my brother-in-law’s funeral a month ago and got bitten by a dog belonging to my sister’s neighbors. After it bit me, that dog also bit other people and dogs, leading its owner to euthanize it.When I informed my sister’s neighbors about their dog biting me, they dismissed it, saying, "It’s just a puppy and can’t bite anyone."

I returned to my place after the funeral and had to get five rabies vaccinations and a wound healing serum shot. I developed a fever after the vaccination, and the doctor said there was a high chance the dog that bit me had rabies.I was also told that receiving vaccinations three days after being bitten, as I did, was too late.

I asked my older sister to inform her neighbors about my vaccinations to gauge their reaction. Even my other sisters said she should talk to them. But she said she could not do it. She said it was my bad fortune, and she could not take care of everyone that went to her husband’s funeral.

She eventually sent me VND5 million (US$206) reluctantly, saying, "Take this. I won’t even dare call you next time my family has an issue."

I explained to her that what I needed was the dog’s owners taking responsibility instead of her money, and that I could not confront them aggressively because they are her neighbors, so I had to ask her to tell them that I was frustrated with their manners.

However, my sister and I have not talked to each other since then.

What should I do?
