Introduction to the signs of Kerry Blue Terrier in heat:

Like other dogs, Kerry Blue Terriers only go into estrus twice a year, usually from March to May in spring and September to November in autumn. When the female Kerry Blue Terrier is in estrus, her body Characteristic signs and behaviors will occur.

Pre-estrus: It is the preparation stage for estrus, which lasts about 7-10 days. The reproductive system begins to prepare for ovulation. The egg is close to maturity, the reproductive tract epithelium begins to proliferate, glandular activity begins to intensify, secretions increase, the vulva is congested, the vulva is swollen, flushed, wet and lubricated, and mucus mixed with blood flows. Male Kerry Blue Terriers often come by scent, but female Kerry Blue Terriers are not allowed to mate.

Estrus: It is the period when the signs of estrus are most obvious and mating is accepted, lasting about 6-14 days. The outside continues to swell and soften, the mucus flowing out becomes lighter in color, and the bleeding reduces or stops. Female Kerry Blue Terrier active or stopped. The female Kerry Blue Terrier takes the initiative to approach the male Kerry Blue Terrier. When the male dog climbs over, she takes the initiative to step down on her waist, face her buttocks towards the male Kerry Blue Terrier, tilt her tail to one side, and open and close her vulva to allow mating. 2-3 days after estrus, the female Kerry Blue Terrier begins to ovulate, which is the best period for mating.

Late stage of estrus: The swelling of the vulva subsides and gradually returns to normal. The temperament becomes quiet. Do not become quiet and do not allow male dogs to approach. It usually lasts for two months and then enters the anestrus period. If you are pregnant, the period after estrus is the pregnancy period.

Blood determination method.

During the female Kerry Blue Terrier's estrus, the female dog's vagina can secrete blood. Counting from the first drop of blood from the female dog's vagina in estrus, the first-time female Kerry Blue Terrier usually secretes blood on the 11th to 13th day thereafter. It is more appropriate to breed for the first time. It is more appropriate for multiparous female dogs to be bred for the first time on the 9th to 11th day afterward. For every 2 years of age or 4 litters of parity, the first breeding time will be advanced by 1 day. In short, the best breeding period for most female Kerry Blue Terriers is 9 to 13 days after the female Kerry Blue Terrier has blood dripping from her vagina. However, there are also a few multiparous female Kerry Blue Terriers who go into estrus for 5 to 6 days after giving birth many times. The vagina will stop bleeding immediately, and you can get pregnant on the 6th to 8th day of mating.

Method for determining the vulva.

If the date of vaginal bleeding of the female Kerry Blue Terrier is not found in time during the estrus period, the best breeding period can be determined based on the color change of the female dog’s vaginal secretions and the degree of vulva swelling. The initial color of the vaginal secretions of female dogs is red. The best breeding period is 2 to 3 days after the color of the vaginal secretions changes from red to straw yellow. In addition, when the female Kerry Blue Terrier is in estrus, the vulva will be swollen and congested obviously. When the vulva edema is significantly reduced and begins to soften, it is more suitable for breeding. You can also use your hands to open the female dog’s vagina and observe when the vaginal mucosa changes from dark red or red to light red or pink.When the color is good, breeding is more suitable.
