1. Don't spread the news yourself, and don't let more people know that you have a "free" dog here.
Relatives still have to be given, because the relationship between relatives is more difficult to coordinate than that between friends.
Between friends, everyone wants it except your best brother. Why not? Count the remaining three: You can't refuse to warn your friend or other relatives that they are leaving, and this friend can't blame you. Why doesn't the remaining one come to a big draw? It will be easier for friends who want your little Teddy to get together and draw lots together.
As for the remaining two little teddy bears, it's up to you to deal with them yourself. If you want to sell it, if you don't want to sell it, just give it directly to your relatives or participate in the lucky draw.
