My 8yr old son would really like a pet and he wants to get a dog, he told me 'it is only a small one and it is quite a clean breed' but I told him that dogs as house pets in Islam is haram But he still really would like one. My question is if there's any exceptions to having a dog a house pet considering its small, clean and doesn't leave fur everywhere?
Categorical impermissibility of pet dogs inside the house. Dogs may, however, be kept outside the main house as guards or hunting dogs etc. In your son's case, an alternate (permissible) pet may be suggested/introduced.
