Outlaw the euthanasia of animals

It's completely cruel and unethical to kill (euthanize, put down, put to sleep, lay to rest, send off) animals because they aren't wanted, take up space, are ill, or have other problems. In an article I recently read, a military service dog was killed because he had problems and was 12 and a half years old. This is ridiculous! He could have lived and brought love to others longer. In order to fix this, we need to outlaw animal euthanization completely. This should not be tolerated!
