I have question guy's at sa mga naka pag breed na, first time kopalang kasi eh, kung APRIL 18, 2012 si madz pinanganak kelan ang eksaktong heat niya? first time palang kasi siyang mai-stud, can someone tell me the process at sign na malapit na siyang magka mens. The vet told me na silent type pala siya na belgian.
Please advise me, para additional knowledge na din and to correct things na male na alam ko.
PS: Malay niyo may mabuong business negotiation dito eheheheheh as a marketer everyone is considered as potential customer/ client hahahahaha 
Thanks!!! 
Like menstruation ng mga girls, the first heat of a dam may vary...
according to an article:
The first cycle will often depend on the size of the dog. Small breeds such, as Chihuahuas or Toy Poodles will come into heat between five and seven months. Large breeds like the Collie, Mastiff or Great Dane may have their first heat cycle at six months but it isn’t unusual for them to delay until they are a twelve to sixteen months. Larger dogs develop at a much slower rate than small dogs.
...
I was advised to stud my dog on her second heat cycle, skip the first... kawawa daw kasi. So from her first heat, I counted 6 months and voila,,, perfect timing
bring your pet to a vet after 9 days of proestrus (first blood) for a vaginal smear test,,, they'll give you the best dates to stud your dog,,,
