Is it a day for a dog to be euthanized when he is sick?

Dogs can only be kept! Can't kill! Lightning protection! There is a man in our village who has a bad heart and conscience at ordinary times. He has a dog and likes to bite people, so he decided to buy it back for home! No one who touches or bites will bite his grandson! Tell his grandson to tie it with a rope and buy a businessman. When his grandson was working, it rained heavily and thundered, killing him. There are ancient words written in the back pot, which have not been seen for some time. Later, he asked God that the child had killed people in his first two lives and killed dogs in his life! It's true! Hope to be cautious!
