Is it permissible to poison dogs if they are causing harm and fear, and their owners have not removed them after being warned?

It is permissible to kill a harmful dog, but since the dog is owned by your neighbor, it is not permissible to kill it initially without his permission. Instead, its owner should be advised to remove it. If the dog's harm is proven and its owner refuses to remove it, the matter can be escalated to the responsible authorities. If these authorities fail to act, it is then permissible to kill the dog, provided that a greater tribulation is not thereby incurred. Scholars have adduced the permissibility of killing a harmful dog by the principle that harm must be removed, and anything that harms or injures people is permissible to kill, including a rabid dog, and indeed any harmful creature should be killed. Caution must be exercised when killing it with poison to avoid harming other unintended animals. If this can be avoided, then killing with poison is permissible, while ensuring that the poison only reaches the intended harmful animal.
