how many months do it take a dog to get on heat?

Answer 1

your dog will probably go into heat for the first time between 6-8 months, and every 6 months after that.

Answer 2

My dog had her 1st heat aged 10 months and it lasted about 3 weeks. They get 2 a year.

Answer 3

How long is a piece of string?

But dogs are on-heat 24/7 by the age of 4 months.
It is bitches that “have a headache today, dear“ most of the time.

See http://www.naiaonline.org/pdfs/LongTermHealthEffectsOfSpayNeuterInDogs.pdf for factual information on the good & bad consequences of neutering at various ages, and then make up your mind as to the best time to neuter her in your household’s situation. My advice to people who can tolerate the blood spots and can GUARANTEE that she won‘t be able to get to a dog are to wait until 1 month after her first season, so that she will be about hormonally mature even though she is still far from physically and mentally mature.

The old wives’ tales, passed on by people who've never gone to the trouble of actually recording WHEN their bitches had each season, will tell you that the first season is at about 6 months old, lasts 3 weeks, and is repeated every 6 months.
That’s not quite rubbish, it just happens to apply to very few actual bitches so is close to a waste of time, rather like telling a gambler that one of the horses in the field will win the race (usually one does, but sometimes the race is abandoned, sometimes the winner is disqualified, but even if all goes well you haven't told the gambler WHICH horse will win).

The age depends on the breed, the bloodlines within that breed, the diet, the distance from the equator (hours of daylight influence it), and whether any other bitches happen to have just come on-heat.

The small breeds often start cycling earlier than the medium-to-large breeds.

In my breed:
Show lines tend to have their first season at 6-9 months old, working lines tend to start at 9-15 months old.
I’ve had one ****** start cycling at 4 months old - but her whole body-chemistry was on “Fast forward” and she died very young from cancer.
I’ve had bitches with heats 4 months apart, 5 months apart, 6 months apart. My current youngest ****** developed pyometritis about 3 weeks after a very-brief season and came back on-heat 3 months after the previous season.
I’ve had a ****** who got pregnant on her 3rd day on-heat; a ****** I sold was kept isolated for 28 days then 2 days later got pregnant by her boyfriend.
To complicate it further, the gap between winter heat and summer heat is NOT the same as between the summer heat and the winter heat! Since I learned to programme my computer I have had it tell me how far between seasons each ****** went. NOT nice & regular, I assure you!


Unless your ****** has top-dogs as her parents, and unless you prove her also a top dog by winning in the show ring and the obedience ring and/or field trials (you don’t say what breed she is), and unless you get all the health certificates appropriate for her breed and then find a stud who (a) has everything I’ve said so far in this sentence PLUS is perfect where she is just very good, then NEUTER HER! The world is not short of pooches, just short of excellent pooches with the attitudes & conformation required by whatever occupation that breed was created to perform. And yes – all REAL breeds were created to perform at least one task. Some, like the GSD, were developed to be capable of LOTS of tasks, but nevertheless a GSD is not a breed-worthy GSD unless it is capable of producing dogs that can do the primary task of a GSD:- boundary patrolling all day (farm dogs don’t keep “office hours”) to keep hungry sheep out of the unfenced crops, and deterring any human or canine predator interested in a free meal of lamb or mutton or thinking of threatening the farmer's family.
The world is ALSO short of people who actually fit that “good home” idea – ask ANY shelter or rescue person!
