What is the ruling on trading in guard dogs that have special characteristics?
It is not permissible to sell dogs, and their price is not Halal (lawful), whether they are guard dogs, hunting dogs or any other kind. It was narrated on the authority of
Abu Mas`ud `Uqbah ibn `Amr (may Allah be pleased with him) that he said:
The Messenger of Allah (peace be upon him) forbade charging a price for selling a dog, the earnings of a prostitute, and the payment offered to a soothsayer.

(Agreed upon by Imams Al-Bukhari and Muslim).
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
