It begins on the first day when the female refuses the male. The dioestrus usually lasts 60 days.The vulva is almost no swelling and this little or no flow.
Anoestrus:
The anoestrus is a period of ovarian inactivity. The vulva is small. anoestrus lasts for about 4 months (possible variations between 1 and 7 months).
The monitoring of "hot":
This is for the master or mistress to learn more about her dog (the changes of mood, the duration of its cycle and characteristics ...).
* First, we must situate the beginning of "heat" by spotting the first day of the bloody vulvar discharge.
* Then, try to determine more accurately the day of ovulation (for a possible coupling). This occurs usually between the 10th and 14th days of heat.
clarification of vulval discharge and reflex posture can help, too, in determining the date of ovulation.
All these facts are noted on the health record of your dog to let you know if it has regular cycles. This may, however, inform the veterinarian if necessary.
Contraception:
* It may be temporary, with the action of a hormone treatment. It is the use of progestins in oral or injectable form, which temporarily stops the sexual cycle. On stopping treatment, fertility returns to normal. If it was initiated before puberty, the dog may remain sterile.
This contraceptive method is very valuable if one wants to wait until the dog has his first puppy. But beware, there may be side effects with this treatment. Ask your veterinarian.
* It may be definitive: it is contraception or surgical sterilization. This involves the removal of the ovaries and uterus. Any risk of heat, pregnancy or infection of the uterus is removed as well.
Tubal ligation also exists but is little used.
For some vets, this type of contraception must be practiced before the first heat for other practitioners, it is preferable that the dog had once had his "hot". Your veterinarian will be an excellent council in the matter.
It is noted that sterilization, whatever its mode, does not aggressiveness or changes in the character of the dog.
COUPLING:
Mating occurs during estrus. The dog must be presented to the female at the time of presumed ovulation, then to 10 - 12th day after the initial blood loss. To promote the chances of fertilization, it is desirable to have them mate at least twice 48 hours apart.
During mating, which lasts about 1 / 2 hours, the dog and the dog are contiguous to each other.It is important not to try to separate them, it could cause injury.
The days before mating, it is advisable to clean the genitals of male and female. For the female one wormed is desirable. Check with your veterinarian.
