The analogy to the permitted categories fails for house-guarding dogs because a thief can trick a dog guarding a house by feeding it something to remove it, allowing the theft to occur. This vulnerability does not apply to a wolf, which is mentioned as a point of comparison for efficacy. Furthermore, keeping a dog inside houses causes harm to passersby, unlike keeping them in the open desert.
