Spaying involves the surgical removal of the ovaries, which are responsible for producing hormones like estrogen and progesterone. These hormones are crucial for regulating the estrous cycle, which includes the urge to mate and the ability to become pregnant.
Therefore, after spaying, a dog's hormonal levels are significantly reduced, and the urge to mate is completely eliminated.
However, it's important to note that some dogs may still exhibit behaviors like mounting or humping even after being spayed. This behavior is often related to playfulness, excitement, or dominance, and not necessarily due to reproductive urges.
If you notice any concerning behavior changes in your dog after spaying, it's always best to consult with your veterinarian for proper guidance and advice.
