Your little story about the natural order of things is exactly why the Gay agenda is to brainwash children before they become sexually aware. They are stealing the innocence of childhood and replacing it with confusion and fear.
Well, it’s not only same-sex dogs who object.
My 60-lb female German Shepherd (God rest her great soul, whether you believe in God or not, never mind about animals...) was dominant and despite never being fixed, didn’t like being dominated.
My sister’s big 110-lb male when younger (not puppy, but close) once tried to “mount” her after they were standing quietly under our tree. She turned on him so hard and nearly bit his head off for that offense, you wouldn’t believe it. She drove him bumbling and rolling some 30 ft away. Never did she show such ferocity any other time. No wounds, but while he was a tough dog, he didn’t touch that subject again.
Was she thus homosexual? ;-)
