Dogs in heat
In general, there is a certain pattern of dog onset, but because of individual differences, some doggies have an emergency once a year, others twice a year, and a few doggies may have an emergency three times a year. So different dogs need different treatment。
I. The first rate
Dogs can reach their first-rate period in the 8-december age group, but some are younger than others because of the wide variety of varieties。
Ii. Seasons of onset
The female is a seasonal single-offer, usually one in march-may or autumn-november. Seasonal outbreaks of good dog breeding are less apparent. There's dogs who get in trouble two or three times a year。
Iii. Periodicity
The she-dog's onset cycle is divided into four periods, i. E. Pre-incident, pre-incident, inter-incident and post-incident。
1. Pre-incident period: placing of blood samples in the vagina of a female to the period of acceptance of a male to climb and cross mating. The pre-incident period lasts 3-16 days, with an average of 9 days, during which the female dog is excited but does not accept mating, external genital swelling and ovaries have ovaries。
2. Intermittent period: during the time of acceptance of the creeping of a female dog, the onset of a female dog is generally 4-12 days, usually 9-12 days. The first acceptance of male mating by a female dog is a sign of the onset of the heat. It is important to determine when the onset of the outbreak begins, as the ovulation occurs at short notice。
3. Period of onset: this is the period between the end of the mother's condition and the return of the genital organs to normal position. The female has a longer period of interrelation, because the ovulation can last about 75 days。
4. Post-incident: the female genitalia is static and lasts 50-60 days, with a single-infested dog per year, for almost a year。
The uterus is permanently at the disposal of the gestationary ketone during each full onset cycle, causing excessive intrauterine growth and cystic changes, as well as a high risk of infection, most of which can be found in older dogs。
