I'm going to adopt a dog at night. What do you think is my fate with it?

If at the time of adoption, it is best not to have many such problems. You should have "love at first sight". When you look at the person who used to look at you most quietly and affectionately, it means that you are doomed to be separated. If you want a humane dog, you can see if its nose is deep. If it is deep, it means it is very human. Of course, the deeper the better.
