Why will my dog not go into heat?

Answer by  dhamotharant (7)

A female has a litter sometimes this rule does't apply and you may find she may't come into heat approx up to 9mths from the date she was firstmated. It takes quite a deal of time for the hormones to get their act together so to speak and even weather,other issues can contribute to females having regular heats or irregular ones.

I assume you mean you want to breed your dog. Female dogs (technical term is bitches) will not go into heat for the first year or two of life depending on breed (larger dogs take longer to go into heat). Bitches above the age of 6 or 7 can experience menopause and no longer breed.

It goes into heat every eight months, after periods then when it is not red anymore it will be in heat for the last five days, since fertile period varies after start of the heat cycle

Dogs only go into heat once or twice a year. Just give it time if your dog is in breeding age and eventually the dog will go into heat.
