One of the most significant transitions in a dog’s life occurs during their progression from puppyhood to adulthood, as their sexual maturity emerges. In male dogs, we can observe their tendency to raise their hind leg to urinate, marking their territory, and displaying more dominant behaviors. In contrast, female dogs begin to exhibit signs of jealousy at around 9 months of age. Generally, female dogs experience heat cycles approximately three times a year, with intervals of four months between each cycle. However, it’s worth noting that the duration and frequency of these cycles may vary for each individual dog due to their unique biological makeup.
