On average an unspayed bitch goes into heat every six months, though this can vary with individual dogs. A bitch's first heat will usually occur between six and 12 months of age, but could be as early as five months or as late as 24 months.
Please note that the American Kennel Club and fanciers of the various breeds always refer to a female dog as a "bitch." As in "my bitch had 4 puppies." The male dog is referred to as a "dog." The word "bitch"used in this way is not considered inappropriate.
First of all, let's do the math here. One year has 365 days, and the average estrous period of a cow is 21 days. So to find how many times a cow will go into heat in one year is 365/21 = 17 days. Thus, a cow (if not bred during that year) will go into heat 17 times in one year.
It is very possible. Most dogs come into heat 6 months apart, but some only go 4 months between heats. Those dogs can come into heat 3 times per year.
The number of times a year a dog goes into "heat" or estrus depends on the dog as an individual. The breed of the dog has no bearing on how often a female dog goes into "heat". ON average female dogs go into Estrus or "heat" twice a year
5-7 times a year, keep her locked up because every dog will be after her .
