Shaykh Umar Farooq Saeedi
Benefits and Issues: Benefit. Islam desires to keep its society free from all those impurities and abominations which are characteristic of dog-worshipping societies. For this purpose, Islam has strictly prohibited its (the dog's) buying and selling.

´It was narrated that Abu Hurairah said:` "The Messenger of Allah (ﷺ) forbade the price of a dog and studding a stallion."
Maulana Ataullah Sajid
Benefit: Cows, buffaloes, goats, etc. are taken to a male (animal) for breeding purposes. The owner of the male animal charges a fee in exchange for mating. This is not correct; rather, this act should be done for the sake of Allah (fi sabilillah). However, if the owner of the female animal, of his own accord and without any demand, offers something, then it is permissible to accept it. See: (Jami' al-Tirmidhi, Book of Transactions, Chapter: What has been reported regarding the dislike of the fee for the stud of a male animal, Hadith: 1274)
