Some breeds are more sensitive to these pheromones than others, with scent hounds like Beagles and Bloodhounds being particularly attuned to these scents. These breeds can detect the scent of a female in heat from over a mile away.

If you're trying to protect your pet from unwanted attention, it's essential to keep them indoors or in a securely fenced area when a female dog in the neighborhood is in heat. The scent of a female in heat can travel through walls and under fences, so a secure enclosure is crucial.
