Why will animal control put a dog down?

Animal control may decide to euthanize a dog for several reasons, primarily related to public safety and the animal's well-being. This can include instances where the dog poses a significant threat to people or other animals, has severe behavioral issues that cannot be rehabilitated, or is suffering from a serious medical condition that cannot be treated. Additionally, if an unadoptable dog is in a shelter with limited resources and space, euthanasia may be considered as a last resort to make room for other animals in need.
