1؎: Taking a wage for mating a male horse, camel, donkey, ox, goat, etc. with female animals is prohibited. However, if something is given as a favor and kindness without any prior condition, then accepting it is permissible. And lending the male animal temporarily (as a loan) is recommended (mustahabb). A group of scholars has also permitted taking a wage for this, so that the lineage (of animals) does not cease. But the majority of the Companions (radi Allahu anhum) and jurists, in light of these ahadith, hold its prohibition.
Explanation & Benefits
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)

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.
