Is the odor resulting from raising sheep considered a nuisance to neighbors, knowing that the sheep are brought into their shelter only at night for protection from theft, and the shelter is washed weekly or bi-weekly?

If neighbors are bothered by the smell of animals (such as sheep and chickens), then it is obligatory to remove the harm from them, either by getting rid of the animals or raising them away from residential areas, due to the religious proofs that prohibit harming neighbors and consider it a grave sin. Jurists have stipulated the prevention of such harm, similar to prohibiting slaughterhouses and tanneries near mosques or houses if they cause harm to neighbors. If keeping sheep overnight leads to an offensive odor, then it is necessary to dispose of them or move them to a distant place. As for pets that are raised inside homes and people are accustomed to raising them, there is more leniency regarding them than for what is not customary.
