Your next dog won't get sick for a few months, but it will get sick in a few days. So think carefully before raising this dog. Convince yourself not to keep it anymore. I thank you.
Well, you should be euthanized. Knock it to death with a stick and bury it. But don't give others trouble, or throw it away.
Don't throw it to small animal protection organizations, and don't throw your troubles to others.
