Sex

Although there is some variation, the first estrus cycle in female English Springer Spaniels usually occurs between 6 to 12 months of age. Depending on the dog, further cycles often happen every 6 to 12 months.

This is the first phase of ovulation. As a result of hormonal shifts, a pregnant female dog may exhibit behaviors such as increased urination, vulvar enlargement, and an increased desire to attract male canines. But at this point in her development, she is not interested in mating.

This part of the cycle is all about mating. A more amiable attitude toward male canines and an eagerness to mate are among the behavioral changes that characterize this condition. Color and consistency of the female's discharge are subject to alter. There is a range of 5–13 days during this phase.

Diestrus is the time after estrus when a woman's reproductive system is no longer susceptible to fertilization. It is possible to establish pregnancy at this period if mating has taken place. In such a case, the female will go into anestrus.

The reproductive cycle of female dogs, including Springer Spaniels, is characterized by distinct phases, one of which is anestrus.

During anestrus, the reproductive system of the female remains dormant, and she is sexually inactive. This period serves as a resting phase between the active reproductive cycles. Anestrus is crucial for the female's overall reproductive health and allows her body to recover before the next cycle begins. It is marked by a lack of interest in mating, and physiological changes occur to prepare for the subsequent stages of the reproductive cycle.

As the anestrus phase concludes, the proestrus cycle initiates the dog's readiness for mating. During this time, if a receptive female is in the vicinity, a male Springer Spaniel is likely to exhibit behaviors indicative of mating readiness. The dog's heightened interest in female canines becomes evident through various behaviors such as vocalizations, pacing, and increased sniffing.

These behaviors are driven by the dog's keen sense of smell, which allows them to detect the pheromones released by a female in estrus. The proestrus cycle marks the beginning of the dog's increased receptivity to mating and sets the stage for the subsequent stages of the reproductive cycle.

Springer Spaniels, known for their energetic and social nature, can be particularly responsive to the presence of a female in estrus.

The breed's eagerness to mate is expressed through their heightened interactions and behaviors that demonstrate their interest in the opposite sex.

This period of increased activity and attention to potential mates is a natural part of the reproductive cycle and plays a vital role in the continuation of the breed. Understanding and observing these behaviors is essential for responsible dog breeding and ensuring the well-being of both male and female dogs during the reproductive process.
