Interesting Facts About Dog Reproduction

Sexual maturity or puberty comes in female dogs when they are about six months old. The breeds that are smaller in dimension usually go into heat or oestrus before six months of age, which can be as early as being four months old. In contrast, larger breeds or giant dogs would probably be a year or older before they come into heat.

Coming into heat is twice a year for most dog breeds, though this can vary. The variability would be greater when cycles first begin. Some females take about eighteen months and develop their regular heat cycles by two years.  In some females, three to four heat cycles in a year are common while in larger breeds the heat cycle comes once in 12 to 18 months.

When female dogs come into heat, this lasts for two or three weeks. There is a vulvar discharge which is the first signs of heat cycle beginning. Females start to pay attention to their vulva by licking it and it appears swollen. Once the discharge ceases and the swelling of the vulva reduces it returns to normal size. Signs of heat also comprise of vaginal bleeding.

Female dogs are receptive to male ones from the time the heat period begins but they are receptive only about 7 to 10 days later. Around this time the discharge is less bloodstained. Some female dogs can experience heavy bleeding of the vagina for which you might want to consult your vet to understand what needs to be done.

If you wish to de-sex your dog they can be taken in when they are in season though in most cases surgery is done about 8 weeks from the start of the last cycle.

Most female dogs are receptive by the 10th day of a heat cycle. At such a time ovulation occurs. Male dogs need to be at least six months of age or more to be ready for mating. Vets can perform tests for your dog in order to determine whether they are ready for mating. It is best to seek out a professional breeder in the area if you wish to get your dog mated successfully. In case you have a female dog, it needs to be taken to the male dog’s home as the latter is known to be more comfortable mating in their own turf. Breeders usually provide one or more mating chances for breeding to be successful.
