Horses and dogs are incompatible.
Affinity genera complement and promote each other. For horses and dogs, they belong to the "trinity" genus, and together with rabbits form the "trinity golden bureau". Therefore, according to tradition, horses and dogs belong to the same genus and can protect each other and cooperate with each other.
However, modern people do not pursue its traditional significance for the coincidence or conflict between genera, but pay more attention to the influence of relative personal fortune. Therefore, whether horses and dogs belong to the same genus is not an inevitable answer. Whether they are consistent depends on personal factors, such as date of birth and luck.
In a word, although according to the traditional view, horses and dogs belong to the same genus, everyone's situation is different and needs to be determined according to the specific situation. So if you want to know the coincidence between genera, you'd better know your birth date and fortune first, and then make corresponding analysis.
